Introduction
Product
Description
Upgradable Sounds
Halo contains a new collection of presets designed for music composition
in a wide variety of styles.These sounds are rich in harmonic texture and a
perfect complement to the Z-plane filters. Halo contains three additional,
user-upgradable sound SIMM sockets, allowing you to mix and match
sound sets according to your needs. New sounds can be added as easily as
plugging in a new 16MB or 32MB SIMM module. Each sound set has been
meticulously crafted to be the finest of its kind. Samples are expertly
matched across the keyboard and perfectly looped to create realistic instru-
ments which form the exceptionally playable presets.
1024 Presets & more
Halo contains 512 user presets and 512 factory ROM presets, but it can be
expanded with literally thousands of ROM presets.
(ROM presets are
automatically added when sound SIMMs are installed. As an example, a 32 MB
SIMM may contain up to 1024 ROM presets.)
Halo’s Sound Navigator makes it
easy to find the exact sound you want. It’s powerful, yet simple to use.
Velocity & Pressure Sensitive Keyboard
The five-octave, velocity sensitive keyboard with aftertouch allows you to
perform live or record via MIDI into an external computer/sequencer. The
keyboard action is extremely responsive, capturing all the subtle nuances of
your performance.
Multi-Function Controllers
Multi-function buttons allow you to trigger arpeggiators and notes inter-
nally or on any of your other MIDI devices. They can act as preset select
buttons or Beats Mute or MIDI Trigger buttons (latched or unlatched).
Four real-time controller knobs are also multi-function controls. These
knobs make it a snap to edit and modify internal preset parameters. The
controllers are fully programmable and can control internal preset or other
MIDI equipment. They can also be programmed to adjust multiple internal
parameters at once, allowing complex levels of control. For example, a
single knob can simultaneously turn up filter cutoff, while detuning one

sample, and adjusting the release time of the volume envelope. Virtually
every synth parameter in the Halo is controllable using the real-time knobs
or by any internal or external control source.
SuperBeats
Beats Mode is a whole new way to create dynamic, original music. With
Beats, you trigger, latch and unlatch synced loops and grooves from the
sixteen trigger keys. Simply select a
bts:
preset and go. Then use Halo’s
perfomance controls to alter and mutate the rhythm or the sound itself.
Multi-Channel Arpeggiators
Halo’s Rhythmic Pattern Generator/Arpeggiator can play up to 16 synchro-
nized arpeggiator patterns at once using a different sound for each! Patterns
can be edited using pattern flow commands such as: delay for 2 bars, play
for 4 bars, hold for 2 beats and repeat. You can program or download 100
user patterns in addition to the 200 factory patterns.
Ultra Powerful Synthesizer
The extremely flexible yet easy to use synthesizer makes it easy to build
sounds of any kind. Up to 4 four layers can be switched or crossfaded using
key position, velocity, real-time controllers or any modulation source. 64
voice polyphony ensures that you can play and sequence the most complex
material. Halo also contains 50 different 2nd to 12th order resonant &
modeling filters which are used to shape and modify over 1200 waveforms
contained in 32 megabytes (MB) of ROM.
Sixty-four modulation sources include three multistage envelopes and two
LFOs per layer, as well as full MIDI control over virtually every parameter.
The digital patch bay, with 24 cords per layer, (and 12 more cords per
preset) lets you connect modulation sources to 64 destinations in any
imaginable way. The patch bay also contains a set of arithmetic modifiers,
allowing you to create complex synthesis models. Synth parameters as well
as arpeggiator and BEAT tempos can be controlled from Halo’s internal
clock (or an external MIDI clock). Up to 8 LFOs and 12 envelopes can be
perfectly synchronized at different rates.
24-bit Effects
Once you have created your preset, you can add richness to your sound
using Halo’s 24-bit stereo effects. You can choose a different effects setup for
each preset from over 60 algorithms. Halo’s effects section is actually two
separate effects processors with control over each wet/dry mix level on four
effects sends. Effects Processor “A” contains primarily ambiance algorithms
like reverb and delays, while effects processor “B” contains primarily
spectral algorithms such as chorus, flange, phase, distortion, and delay.
Effects can be linked to each preset or used globally for increased flexibility.
Other features include multiple solo, voice assignment and performance
modes for expressive control, 12 user-definable alternate tunings, and, of
course, an extensive MIDI implementation.

grounding provides a path of least resistance for electric current, reducing
the risk of electric shock. This product is equipped with a cord having an
equipment-grounding conductor and a grounding plug. The plug must be
plugged into an appropriate outlet properly installed and grounded in
accordance with all local codes and ordinances.
Danger!
Improper connection of the equipment’s grounding conductor can result in
the risk of electric shock. Check with a qualified electrician or service
personnel if you are in doubt as to whether the product is properly
grounded. Do not modify the plug provided with this product. If it will not
fit the outlet, have a proper outlet installed by a qualified technician.

Interference
The equipment described in this manual generates and uses radio-
frequency energy. If it is not installed and used properly —that is, in strict
accordance with our instructions— it may cause interference with radio
and television reception.
This equipment has been tested and complies with the limits for a Class B
computing device in accordance with the specifications in Subpart J of Part
15 of the FCC rules. These rules are designed to provide reasonable
protection against such interference in a residential installation. However,
there is no guarantee that the interference will not occur in a particular
installation, especially if a “rabbit ear” TV antenna is used.
If Halo does cause interference to radio or television reception, you can try
to correct the interference by using one or more of the following measures:
•
Turn the television or radio antenna until the interference stops.
•
Move Halo to one side or the other of the television or radio.
•
Move Halo farther away from the television or radio.
•
Plug Halo into an outlet on a different circuit than the television or
radio.
•
Consider installing a rooftop antenna with a coaxial lead-in between the
antenna and television set.

Instructions
Power Switch & AC Receptacle
The AC power switch is located on the rear panel. There is no 110/220 Volt
power selector switch since Halo utilizes an auto-switching power supply
which accepts from 100V-250V, 50-60Hz.
MIDI Output
The Halo can control other MIDI instruments by connecting a MIDI cable
between the MIDI out of Halo and the MIDI Input of the other instrument.
The Right Main output
jack carries a mono mix of the
left and right channels when the
Left Main plug is not plugged in.
The Left Main output jack is a
stereo jack carrying both
channels when the right output
jack is empty.
Outputs
In order to reproduce Halo’s wide dynamic range and frequency response,
use a high quality amplification and speaker system and a stereo setup is
highly desirable The headphone output is the same as the Main output
signal. The headphone jack is located on the left side of the front panel.
Footswitch & Footpedal
Connect a momentary footswitch and a Control Pedal for additional
control. Halo auto-senses either normally-open or normally-closed switches
See page 15 for information about how the footpedal should be wired.

MIDI In/MIDI Out
Halo can be connected to a computer/sequencer via the MIDI In and MIDI
Out ports. Halo to playback complex multitimbral sequences.
Audio Outputs
Two pairs of programmable stereo outputs (Main and Sub 1) are provided.
The internal effects are available only on the Main outputs. Specific presets
(or MIDI channels) can be routed to one of these stereo pairs in order to be
processed further or mixed separately.
Footswitch & Footpedal
The footswitch input accepts either a normally-open or normally-closed
momentary footswitch. The footpedal input can sense either 0-5 volts on
the ring of a stereo jack or a pedal with the potentiometer wired as shown
at left. The footswitch and Pedal inputs are programmable in the
Controllers, Footswitch menu and the Preset Edit, PatchCord menu.

Selecting and Quick Editing Presets
The first four banks are USER locations that can be overwritten and used to
store your own presets. The presets that come stored in the USER presets are
duplicated in banks 0-3 of the “Halo” ROM bank, so feel free to overwrite
them with your own presets. You won’t be losing anything.
The ROM Card identifier is shown in the top right of the display. The preset
is identified in the bottom line of the main screen (the screen that appears
when you press the Mode/View Preset button).
Each bank of 128 presets is identified by a superscripted Bank Number to the
right of the preset number. The bank numbers reset to 0 at the start of each
ROM card you have installed. So with the “”HALO ROM installed, the USER
banks will go from 0-3, then start over from 0-3 for the Halo ROM banks.
The four User Banks can hold 512 custom presets. Feel free to overwrite these since the
factory user presets are duplicated in nonvolatile ROM.
To the right of the preset number and bank is the preset Category name
followed by the Preset Name.
To Change the Preset:
1. Select the main Preset Selection screen by turning off all the menu
buttons below the LCD.
2. The cursor will be located under the first character in the Preset Number
field. This is the “Home” position which is selected instantly when you
press the Home/Enter button. Pressing either of the two cursor buttons
repeatedly also gets you there.

Arpeggiator
Halo is totally amazing in its ability to run up to 16 arpeggiators at once!
Even two or three patterns at once can create very complex sequences and
dynamic landscapes of sound.
Here’s one way to access this ultra-powerful feature. There is one arpeg-
giator for each MIDI channel. First you’ll assign three of the Trigger Keys to
MIDI channels 01-03. Next, you’ll assign arpeggiator presets to these
channels. Then you’ll become addicted to this new way of making music.
Program the Trigger Keys
1. Press the Controllers button, then turn the data entry control until the
screen shown below appears.
2. Move the cursor to the lower line and turn the data entry control to
select “Play Note Events”. This sets the Trigger Buttons to play note
events instead of selecting Beats parts.
3. Move the cursor back to the top line and scroll to the screen shown
below.
4. Move the cursor until it is underneath the Latch field and turn Latch
mode On.
5. Move the cursor until it is underneath the Channel field (Ch) and set
the Channel to 01.
6. Move the cursor until it is underneath the Trigger field (T1) and
change the Trigger to T2 (trigger button 2).
7. Turn Latch On for trigger button 2 and set the channel to 02.
8. Change the Trigger to T3 (trigger button 3).
9. Turn Latch On for trigger button 3 and set the channel to 03.
Set up the Presets

The Halo front panel contains an LCD screen, 35 buttons, and 4 real-time
controller knobs. Functions are grouped logically and the controls are
arranged for ease of use.
Power Switch The power switch is located on the rear panel next to the AC power
receptacle.
Volume Control This control is the master volume control for all audio outputs. The Volume
Control does not affect any editing or user interface operations.
The front panel volume control is a digital attenuator. For maximum
dynamic range, turn this knob all the way up and control the volume from
your mixer or amplifier.
Channel +/- Buttons These very handy buttons, located to the left of the LCD, serve as a shortcut
to increment or decrement the MIDI Channel (in Preset mode), Layer (in
Preset Edit mode) or Step Numbers (in Arpeggiator Edit mode).
Data Entry Control The data entry control is a stepped, variable control switch used to change
parameter values. The wheel increments or decrements the current value

one unit with each click. This control incorporates acceleration, which
advances the value faster if the data entry control is turned quickly.
Cursor Buttons These buttons, located just above the Data Entry Control, move the cursor
to the next parameter on the display. (The cursor is a little flashing line
underneath one of the parameters in the display.) Press either cursor button
until the cursor is underneath the desired parameter. The cursor buttons
have an auto-repeat feature which advances the cursor when the button is
held continuously.
The cursor can be moved bidirectionally using the data entry control while
either cursor select button is held down (for example, press and hold the
right cursor button and turn the data entry control).
Pitch & Mod Wheels These two controls, located to the right of the keyboard, are performance
expression controls. The left “Pitch Wheel”, is spring-loaded and is
normally used to bend the pitch up and down while playing. The center
position is off. The pitch bend range is set using the “Pitch Bend Range”
parameter in the Global menu (page 84).
The right “Mod Wheel” is programmed to add vibrato in most of the
factory presets. Like all the controllers in Halo, the Mod Wheel can be
programmed to control any synthesizer parameter. See PatchCords on
page 102 and page 157 for more information.

Controllers Button The Controllers menu contains parameters that are related to the front
panel controller knob and button triggers. An illuminated LED in the
button indicates that you are in the Controllers menu. For more infor-
mation about the Controllers menu, see page 71.
Arp/Beats Button The Arpeggiator menu contains parameters that are related to Beats mode
and the Master Arpeggiator. Beats is a 16-track play-only sequencer that is
optimized for live performance and groove creation. An illuminated LED in
the button indicates that you are in the Arp/Beats menu. For more infor-
mation about the Arp/Beats menu, see page 43.
MIDI Button The MIDI menu contains parameters that are MIDI related. An illuminated
LED in the button indicates that you are in the MIDI menu. For more infor-
mation about the MIDI menu, see page 93.
MIDI Panic Button Pressing the MIDI and Home/Enter buttons simultaneously sends a MIDI
“All Notes Off” and “All Sound Off” for all 16 MIDI channels. This immedi-
ately kills all sounding notes internally and over MIDI.
Audition Button When the Audition button is pressed, the LED next to the button will
illuminate and a short “Riff” (programmed as part of the preset) will play.
The Riff is latched on and plays continuously until the button is pressed
again. Presets can be changed while Audition is latched on. See “Bank Select
Commands” on page 126 for more information on selecting banks via MIDI.
The top line of the Preset display changes to show the MIDI Bank Select
controller values needed to select the preset being auditioned. This handy
feature lets you know the exact Bank and Preset number.
Compare Button The Compare button allows you to toggle between an edited version of a
preset and the original, unedited version. When a preset has been edited,
the Save/Copy LED flashes. Press the Compare button, lighting its LED, to
hear the unedited preset. Press the Compare button again to hear the edited

has been changed. The MIDI A-L values are stored in the corresponding
Initial Controller Amount parameter in the Preset Edit menu (see “Initial
Controller Amount” on page 167). The Save/Copy button LED flashes to
remind you that the preset has been edited. “Quick-Edits” made to a preset
are lost if you select another preset before saving them.
The three rows of knobs always control the preset on the basic MIDI
channel (the channel showing on the preset select screen), when the
control switch is set to Quick Edit.
The labels (Filter Cutoff, Filter Q, Filter Attack, Filter Decay, etc.) printed on
these rows show how the factory ROM presets are programmed to respond.
(The controls may not exactly conform to the front panel labels depending on the
preset.) You can change the way a preset responds to MIDI A-L messages
from the Preset Edit menu (PatchCords). The knobs only generate a
message when you move a knob to a new value. The current value jumps to
the new value.

Beats Halo contains a 16-track play-only sequencer that is optimized for live
performance and groove creation. Halo contains dozens of special 16-part
Beats Riffs created by some of the best producers in the business. Beats Riffs
are normally used in conjunction with a “bts:” preset containing the appro-
priate percussion mapping, but any preset can be selected and used.
The Beats channel is selected from the Beats enable screen in the Arp/Beats
menu.
Here’s how it works. Each of the 16 parts is assigned to a trigger key on the
selected Trigger MIDI channel. Each part is brought in or out by pressing
that key. Keys can also be Latched (press the key once to turn the part on, press
it again to turn the part off). Other control keys allow you to Mute All Parts,
Clear All Parts, and Start & Stop the beat. The 16 parts are arranged in the
following manner:
For each Beats Riff, you have 2 Grooves, 4 Fills which correspond to the
four parts of the Main and Alternate groove, and 4 Instrument parts. By
adding and removing parts, you control the complexity of the groove.
__
__ Beats (bts:) Riffs are
special 16-part riffs made
especially for use with Beats
mode. A Riff without the bts:
prefix only has Part 1 recorded.
Each part can also be scaled by Key Velocity, allowing you to fade parts in
and out (if velocity is routed to volume) as you play, or can be Transposed
over a six octave range.
Each part can be assigned to any one of four Groups, which allow multiple
parts to be triggered from a single key. You can only access Groups using
the keyboard trigger keys. See the Factory Setup diagram on the next page.

Buttons (page 76) to the

Beats Controllers
Beats Controllers Beats can be controlled using the front panel real-time controllers or
external MIDI continuous controllers. Controllers are patched to Beats
via the Preset PatchCords located in the Edit menu. The following Preset
PatchCord destinations control Beats.
Beat Velocity Group 1-4 (BtsVelG1 -> BtsVelG4)
Parts assigned to one of the four Beats groups can have their velocity scaled
by the controller input. Since most “bts” presets have velocity controlling
volume, this control can be used to mix the relative levels of the Groups.
Beats velocity works as a percent addition. An input value of 0 (or no Cord)
means change the velocity by 0%. A full scale modulation setting of 100%
in the PatchCord adds 100% to the velocity value 100% + 100% = 200%. A
PatchCord setting of -100% subtracts 100% from the velocity (making it 0).
Beat velocity scalings are reset with a preset change.
Beat Xpose Group 1-4 (BtsXpsG1 -> BtsXpsG4)
Parts assigned to one of the four Beats groups are transposed by the
controller input. Transpose works by shifting the keyboard position and
not by changing the tuning of individual notes. Therefore, on a Beats
presets (bts), where different instruments are assigned to each key,
Transpose has the effect of changing the instrument used by a particular
part. This control ADDS to the Part Transpose set in the Beats Transpose
screen (page 53). Beat transpose offsets are reset with a preset change.
Beat Busy (BtsBusy)
The Mod 1 controller
knob is assigned to Beats Busy.
This destination determines which parts are enabled. Beat Busy will accept
either positive or negative values.
•Positive values Add parts to whatever parts are triggered
•Negative values Remove parts that are triggered.

OO
OO A PatchCord amount of
50% is enough to drive Beat
Busy to the maximum setting.
Suppose the pitch wheel (which can output both positive and negative values)
were connected to Beat Busy and four Key Triggers are down. As the pitch
wheel is moved from center to fully up, the remaining parts will be enabled
until the pitch wheel is fully up and all parts are playing. Moving the pitch
wheel from center to fully down, the four triggered parts are sequentially
removed until at the most negative position of the wheel, no parts are
playing.
OO
OO Hot Tip!
The Bidirectional Mod Wheel:
Set Mod Wheel to BtsBusy with a
Cord amount of +100, then add
a DC bias to BtsBusy with a Cord
amount of -50. Wheel now adds
or subtracts “Busyness”.
The Busy control acts on the Beats condition whenever the control is
changed. Playing more triggers without changing the Busy control simply
adds them until the Busy control is changed again, at which point it will
possibly add or subtract parts as needed.
The interaction between the Busy control, Triggers, Part Velocity and Group
Velocity can get complicated, but works according to this rule:
WHICHEVER CONTROL WAS LAST CHANGED TAKES OVER
When interacting with the Group Velocity scale control, the Busy control
ignores group velocity even when it is set to zero, enabling and disabling
parts as necessary. If the Group Velocity is changed after the Busy control, it
takes control, scaling parts as it deems necessary.
The Busy control does take the Part velocity into account when adding and
subtracting parts. If a part has a velocity of 0%, it is removed from the list of
parts that the Busy control adds or subtracts. Therefore, you can use the
Part Velocity control to remove parts you don’t want to hear.
OO
OO Cool Tip! Connecting
Key Pressure to Beat Busy at
50% increases BEAT complexity
the harder you press.
Beat Variation (BtsVari)
The Mod 2 controller
knob is assigned to Beats
Variation.
Beat Variation varies which Parts are brought in and out using the Beat
Busy control. Increasing this control mixes up the order in which Parts are
brought in and out, thus providing even more permutations to the Beat.
Played

Busy
Brings in Parts
Removes Parts
Positive controller values bring in new Parts and negative controller values remove

Beat Busy since it outputs negative as well as positive values.

moves the group of triggers up the keyboard by the designated number of
keys. Negative offsets move the trigger group lower on the keyboard.
Beats Keys Offset slides the entire group of beats triggers up or down the keyboard.
Beats Part Velocity Each note of a Beats Riff can have its recorded velocity scaled by a value
(from 0 to 120%) of the recorded velocity or the actual played velocity of
the trigger key can be used (trigger vel). For example, if a note’s velocity is
80, scaling by 110% will increase the note’s velocity to 88. This feature
allows you to control the mix of the different parts in advance or “on-the-

Arpeggiators
Arpeggiators An arpeggiator moves a pattern of notes sequentially over a range of the
keyboard. Halo has the unique ability to play a different arpeggiator on
each MIDI channel!
Arpeggiator settings can be defined as part of the preset (using the Arp
parameters in the Preset Edit menu), or globally in the Arpeggiator menu.
The preset and master arpeggiators have the same parameters which we
define in this chapter.
The Arp field in the main screen defines which arpeggiator settings will be
used. “M” uses the master Arpeggiator settings and on/off status (as defined
in the Arpeggiator menu). “P” uses the preset’s arpeggiator settings and on/
off status (as defined in the Edit menu). Choosing “On” uses the preset’s
arpeggiator settings regardless of whether or not it is turned on in the Edit
menu and Off turns off the arpeggiator regardless of the settings and status
specified in either menu.
__
__ SAVE your Arp setups
and name them using the “Save
Setup To” function located in the
Multi menu. See“Saving
Multisetups” on page 42.
All arpeggiators share Halo’s master clock and its current setting. The
master clock can be Halo’s internal clock or an external MIDI clock
(page 82). Although the arpeggiators use the master clock setting, the
tempo divisor can be unique for each arpeggiator setup.
Arpeggiator modes include up, up/down, forward assign, backward assign,
forward/backward assign and random as well as play Patterns. Patterns are
pre-recorded sequences of notes and rests. All key-on notes play the
pattern. For example, if you play a chord, all the notes in the chord play the
pattern in harmony. Halo contains 200 factory patterns and 100 user
definable patterns.

parameter is used in non-pattern mode only.
Following is a list of possible Note Values and the relative number of clocks
used for each.
Note value has no effect
when the mode is set to
“pattern.”

Arpeggiator Pattern
Speed
The Arpeggiator Pattern Speed parameter lets you change the playback rate
of Patterns by 1/4x, 1/2x, 1x (normal), 2x or 4x normal speed.
Pattern This field lets you choose the pattern used when the arpeggiator Mode is set
to “Pattern.” There are 200 factory programmed patterns and you can
create an additional 100 user definable patterns (see “Editing a User Arpeg-
giator Pattern” on page 67).

Master Arpeggiator Parameters
Velocity The Velocity parameter determines the velocity at which each note arpeg-
giates. Velocity can be defined by the velocity value specified (from 1
through 127), or by the actual velocity of the played note (played). Bear in
mind that velocity values do not have an effect on the sound unless the
preset is programmed to respond to velocity.
Controller Knob O is
programmed to control Arp
Velocity.
Gate Time The Gate Time parameter works together with the Note Value parameter.
Just as Note Value defines the length of a note, the Gate Time sets the
percentage of the Note Value time played. This can have a dramatic effect
on the sound depending on how the envelope generators are programmed.
Controller Knob P is
programmed to control Arp Gate
Time.
The note-on time is used
for the start-of-time when
calculating note durations. See
“Duration” on page 64.
With a Gate Time setting of 100% the note is held on until the next note
starts. The envelope generators never advance to the Release stages. With a
Gate Time setting of 50%, the note is released halfway through the note
cycle and the envelope generators proceed to their release stages until the
next note occurs. Refer to the following illustration.

Master Arpeggiator Parameters
Extension Count The Extension Count parameter specifies how many times the Extension
Interval is carried out. With an Extension Count of 0, the arpeggio plays
only the notes pressed. With an Extension Count of 1, the arpeggio plays
the notes pressed, then plays the same notes (in the same order), trans-
posed by the Extension Interval amount. The cycle is then repeated.
For example, with the Extension Interval set to 12 (an octave) and an
Extension Count of 2, and with the Arpeggiator Mode set to Fwd Assign, if
you played E2, then C2, then G2, the arpeggiated sequence would consist
of: E2, C2, G2, then E3, C3, G3, and then E4, C4, G4. The Extension Count
values range from 0 through 15. Refer to the following illustration.
Extension Interval The Extension Interval specifies the additional intervals played when you
press a key. For example, suppose you played C2 with an Interval of 7 (a
Major 5th), Up mode, and an Extension Count of 2. The arpeggio alternates
between C2 and G2.
The Extension Interval values range from 1 through 16.

Master Arpeggiator Parameters
Sync The Sync parameter defines when a note is played in relation to when the
key is pressed. When set to “Key Sync”, the note sounds the instant a key is
pressed. When set to “Quantized”, the note does not sound until the next
occurrence of the selected note value.
The following diagram illustrates how Key Sync and Quantize work.
Pre-Delay The Pre-Delay value determines how long the arpeggiator is delayed before
becoming active after the first “note-on.” During the pre-delay period,
notes are played normally (as if the arpeggiator was off). After the pre-delay
period has elapsed, the arpeggiator kicks in. Once you release all the keys
on the controller, the pre-delay starts over with the next note-on. In combi-
nation with the Duration parameter, Pre-Delay lets you create many more
variations in the arpeggio patterns. Please refer to the diagram on page 65.
You can play the preset normally as long as you don’t hold the notes longer
than the Pre-Delay. If you do, the arpeggiator starts in. When used in
conjunction with multiple arpeggiators, Pre-Delay allows you to offset the
time between the different patterns.

Master Arpeggiator Parameters
Duration This parameter defines how long the arpeggiator plays before stopping. The
Duration is specified in note values. Therefore if an arpeggio were running
at a 16th Note Value and the Duration were set to a whole note, the arpeg-
giator would play 16 steps before stopping. After the duration has elapsed,
the arpeggiator remains inactive until the key is released. If Duration is set
to Off, the arpeggio repeats as long as the notes are held (Infinite Duration).
Duration can be used to modify the patterns and increase the possible
pattern combinations and variations. Because this parameter limits the
length of arpeggiator play time, it can change the arpeggio pattern when
the Duration is less than the length of the arpeggio. You can set the
arpeggio to repeat continuously using the Recycle function described below.
Post-Delay This parameter is only relevant when both the “Duration” and “Recycle”
parameters are not in the “Off” state. The Post-Delay value determines how
long the arpeggiator is delayed after the Duration period. Please refer to the
diagram on page 65. During the post-delay period, notes are played normally
(as if the arpeggiator was off). After the post-delay period has elapsed, the
arpeggiator either jumps to the beginning of the Pre-Delay period or to the
beginning of the Duration period depending on the Recycle setting.
If the arpeggiator is playing an extension when the Duration expires, the
notes in the extension will continue to sound during the Post-Delay (and
Pre-Delay if on). On the next pass through the Duration period, the
extension continues where it left off.
Post-Delay increases the number of possible variations in the beat and
allows the recycle loop to be set to an exact measure of time.

Master Arpeggiator Parameters
Recycle Recycle enables the pattern or arpeggio to repeat. This parameter works
together with the Duration and Pre/Post Delay parameters to allow the loop
to be set to an exact measure of time. The “on/No-PreDelay” option
bypasses the predelay period. With Recycle turned Off, the pattern or
arpeggio stops at the end of the Post-Delay period.
Keyboard Thru When enabled, Keyboard Thru merges the notes not arpeggiated with the
notes being produced by the arpeggiator. This gives the effect of two parts
playing at once.
Latch With Latch mode On, any notes you play remain on until you press them
again. Latched notes can also be halted by turning Latch off in this screen,
or by turning off the Arpeggiator for the channel in the main screen.

Editing a User
Arpeggiator Pattern
Halo lets you create and edit your own arpeggiator patterns. Using the Edit
User Pattern menu, you can create up to 100 user patterns and each pattern
can be up to 32 steps in length.
When you edit a pattern, you are writing directly into memory—no Save
command is required (however, you must exit the Arp module). This is
different from the Edit menu where you must Save a preset before it will be
overwritten. If you want to modify an existing pattern and keep the
original, you must first COPY the pattern you want to edit to another
location using the function in the Save/Copy menu (See page 191). Refer to
the instructions below and the following parameter descriptions to create
your own patterns.
Bank 0 = User Patterns
Bank 1 = Factory Patterns
Bank 2 = Factory Patterns
To Select the Pattern to Edit:
OO
OO Before editing a Pattern,
select Master Arpeggiator (M) in
the main screen and set the
Arpeggiator to the Pattern you
are editing. This lets you hear
the Pattern as you edit it.
1. From the Edit User Pattern screen shown above, move the cursor to the
bottom line and select the pattern you want to edit. The Enter LED
begins flashing. Press Enter to move back to the Home position.
2. Select the next screen in the list, “User Pattern Edit”. This is where you
edit the currently selected pattern.
3. Move the cursor to the lower line of the display. For each step, you can
select: key, velocity, duration, and number of repeats.
Pattern Step Number You can set up to 32 steps for each arpeggiator pattern. This field selects
which step you will be editing from 1 to 32.
Key This parameter defines what happens during the current step. The Key
parameter can do one of five different operations. Following is a description
of each of the key functions and how to use them.

Key Offset
This parameter defines not the actual note of the arpeggiator playback, but
instead specifies the amount of offset, in semitones, from the original note
played. You can set a Key Offset from -48 to +48 for each step. For example,
if you play a “C” on the keyboard with the Key Offset amount for the first
step set to “+1,” the first step in the pattern will be “C#.”
Tie
This function extends the duration of notes beyond the values given in the
duration field by “tying” notes together. You can tie together any number
of consecutive steps.
__
__ IMPORTANT: The Gate
function in the arpeggiator
MUST be set to 100% when
using the tie function, otherwise
the tied note is retriggered
instead of extended.
Rest
Instead of playing a note, you can define the step as a Rest. The Duration
parameter specifies the length of the rest. Rests can be tied together to form
longer rests.
Skip
This command simply removes the step from the pattern. The Skip feature
makes it easy to remove an unwanted step without rearranging the entire
pattern. You’ll be happy to know that the velocity, duration and repeat
parameters are remembered if you decide to put the step back later.
End
This command signals the end of the pattern. Any steps programmed after
the step containing the End command are ignored.

Velocity Each note in the pattern plays using either a preset velocity value (from
1 through 127), or using the actual velocity of the played note (ply).
Note: Velocity values will not have an effect on the sound unless velocity is
programmed to do something in the preset.
Duration This parameter sets the length of time for the current step, defined as a note
value, based on the Master Tempo. The selectable note durations are
described below.
Repeat Each step can be played from 1 to 32 times. A repeat setting of “1” indicates
the step will be played one time (not repeated one time or played twice).
To Edit a User Pattern:
1. The first field in the Edit User Pattern field defines the pattern’s step
number. Start with the pattern Step 01.
2. Define the Key Offset, Velocity, Duration and Repeat values.
3. Repeat steps 1 and 2 until you have setup the desired number of steps
in the pattern.
4. Set the Key Offset to “End” on the last step in the pattern.

Functions
This section describes how set up the Realtime Controllers on Halo.
Realtime Controllers are performance controls such as the controller knobs,
velocity & pressure sensitive keyboard, and the trigger buttons.
Keyboard Channel This option allows you to select which channel is controlled by the
Keyboard, Knobs as well as the Pitch & Mod Wheels. You can select any of
the 16 channels or “Basic”. If the “Basic” channel is selected, the keyboard
and knobs always control the preset showing in the Main screen.
in Quick Edit mode the
front panel knobs only control
the “Basic Channel”.
Keyboard Transpose This option allows you to offset the transposition of the keyboard in
semitone intervals. This is allows you to easily play in different keys with
the keyboard and lets you access different groups of instruments in a drum
map. The transpose range is ±36 semitones.
Local Control On/Off Local Control is used to disconnect the keyboard and controllers (knobs,
wheels, footswitches) from the sound generating section. Even though
disconnected from the internal synthesizer, the keyboard and controllers
are still transmitted over MIDI. Local Control is normally turned Off when
recording into an external MIDI sequencer (set sequencer to Echo Thru).
Played data and recorded data are merged in the computer sequencer and
then sent back to the module. This feature can also be used if you want to
control another MIDI sound generator from the keyboard and knobs
without playing internal sounds.

generated when you continue to press the keys after the note has been
played. Aftertouch can be a very useful controller for adding a bit of vibrato
or creating a volume swell. Aftertouch is routed to the Pressure source in
the PatchCord screen. This control allows you to turn aftertouch on or off
without having to modify each preset.
Footswitch Function The footswitch jack on Halo’s rear panel can be programmed to perform a
variety of functions. The footswitch jack is designed to accept a momentary
footswitches which shorts the tip and ground. Halo senses either normally-

MIDI Footswitch Assign
Note: Controllers 7 and 10 are already assigned to Volume and Pan for each
MIDI channel. Controllers 91 & 93 are the standard controller numbers for
reverb and chorus send amounts, but are not assigned.
Following are a few of the standardized MIDI Controller numbers as
defined by the MIDI manufacturers association. The controllers shown in
Bold are automatically routed to the destination (volume & pan) or have
their own PatchCord source. Others, such as Portamento Time, can be
routed using a PatchCord to have the desired effect.
MIDI Footswitch
Assign
Like the MIDI Controllers, you can assign three MIDI footswitches to MIDI
footswitch numbers. Footswitches numbers are from 64-79. Destinations
for the footswitch controllers are programmed in the PatchCord section of
the Preset Edit menu. The rear panel footswitch 1 is connected to
footswitch controller 1 in this screen. Pressing the footswitch transmits on
the MIDI controller number programmed here. Footswitches 2 & 3 route
incoming MIDI footswitch data to the PatchCord section of Halo.
Calibrate Controllers This screen allows you to calibrate the Pitch Wheel, Modulation Wheel,
Aftertouch, and Foot Pedal controller. The controls should be recalibrated
periodically in order to compensate for normal changes in the controls
themselves. If a control doesn’t seem to be responding properly, it may
simply need to be recalibrated.
The Controllers should
ALWAYS be calibrated after you
reinitialize user data. (And you
should always reinitialize user
data after updating the
operating system.)

To Calibrate the Controllers:
1. Press the Global button. Its LED will illuminate.
2. Turn the data entry control to select the “CALIBRATE CONTROLLERS”

3. Move the cursor to the lower line of the display and rotate the Data
Entry Control to select the control to be calibrated. The choices are:
•Mod Wheel •Pitch Wheel •Foot Pedal •Aftertouch
4. Press Enter to select a control, then follow the instructions given in the

(minimum through maximum), then press Enter.
5. In the case of the Pitch Wheel, you first move the wheel through its
min-max range and leave the wheel resting in its center position. Then
press Enter.
Tempo Controller This function allows a MIDI controller to change the Base Tempo of the
Master Clock. The Master Clock is used by the arpeggiators, clock divisor
PatchCords, tempo-based envelopes and synced LFOs. (See “Clock
Modulation” on page 106.) You can assign any controller number from 0-
31, mono key pressure, or the Pitch Wheel to change the Global Tempo.
A different controller can be used to change the tempo up or down. The
Pitch Wheel can be assigned to both the up and down parameters to vary
the tempo up and down from a single controller. If any other controller is
assigned to both the up and down parameters, Halo redefines the center of
the controller’s range as zero (so it acts like a pitch wheel).
MIDI Controller values are added to the Base Tempo with a range of ±64.
When the controller is set to “off” the tempo returns to its original setting.
Controllers are only recognized on the selected MIDI channel, unless Halo
is in Omni mode, in which case all channels are accepted. This control has
no effect when using an external clock.

Base Tempo
Base Tempo Halo contains an internal Master Clock which runs the arpeggiators,
synchronizes the LFOs when in tempo-based mode, controls the times of
tempo-based envelopes, and can be used as a modulation source in the
PatchCords section.
You’ll notice that there are two tempo values shown in the display.
•Base Tempo - This is the base tempo setting before being modified by
the Tempo Controller (if engaged). See “Tempo Controller” on page 81.
The Arp/Beats LED
flashes in time with the Base
Tempo.
•(Current Tempo) - This is the actual tempo! The current tempo is
equal to the base tempo modulated by the MIDI controller specified in
the Tempo Controller screen. If no MIDI Tempo controller message has
been received since the last Base Tempo change, the Current Tempo will
be equal to the Base Tempo.
To Change the Base Tempo:
1. Move the cursor to the lower line of the display.
2. Adjust the Base Tempo using the data entry control.

Parameters
Global setup parameters affect overall performance, range, and global
effects. This section describes the Global parameters and how to define
them.
Master Transpose/
Tune
The Transpose parameter transposes the key of all presets, in semitone
intervals. The transpose range is ± 24 semitones.
Master Tune adjusts the fine tuning of all presets so that you can tune Halo
to other instruments. The master tuning range is ± 1 semitone in 1/64th
semitone increments (1.56 cents). A master tune setting of “+00” indicates
that Halo is perfectly tuned to concert pitch (A=440 Hz).
Master Bend Range The Master Bend Range parameter sets the range of the pitch wheel. This
affects only presets that have their individual Pitch Bend range (defined in
the Preset Edit menu) set to Master. See page 160. The maximum pitch bend
range is ±12 semitones or one octave in each direction.

Defining Global Parameters
Mix Output The Mix Output parameter allows you to override the routing assignments
made in each preset and instead assign the outputs according to MIDI
channel. For each of the 16 MIDI channels, you can select Send 1-4, or
Preset. When Preset is selected, the output assignment defined in the Preset
Edit menu is used.
The Output Routing field (pointed to by the arrow) reflects the true
routing of Send 2 or Send 3 to either:
1) the effects processor input or… 2) the rear panel submix jacks.
Since the Sub 1 output is NOT being used, the signal is routed through the
effects processors, then on to the main outputs. If a plug were inserted into
one of the Sub 1 jacks the destination field would read “Sub1” for Send 2
and the dry signal would be routed directly to the Sub 1 outputs on the
back panel.
Send Routings
Send 1 - Main Outputs
Send 2 - Subout 1 or Main Outs
Send 3 - Main Outs
Send 4 - Main Outputs
The Sends function as effect processor inputs (effect sends). Send 2 is also
used to route sounds to the Sub 1 outputs on the back panel. When a plug
is inserted into the associated Submix jack on the back panel, the Dry
portion of the Send is disconnected from the effects processor and the
signal is routed directly to the output jack. The Arrow points to the actual
output routing. If you don’t want the wet portion of the signal in the main
mix, turn down the Send Level. The entire Send is disconnected from the Effects
Processors even if only one plug is inserted into the Submix jack.
The four Effect Sends allow you to get the most out of the two effect
processors. For example, with Effect B set to an echo algorithm, you could
route one MIDI channel to Send 3 and set the effect amount to 80%.
Another MIDI channel could be routed to Send 4 with an effect amount of
only 5%. This is almost like having two different effects!
The Mix Output function is also useful when sequencing since it lets you
route specific MIDI channels to specific Sub outputs (on the back panel)
where there they can be processed with EQ or other outboard effects.

Master Effects
Master Effects The digital effect processors can be programmed as part of the preset (using
the Preset Edit menu) so that effects will change along with the preset.
However, there are only two effect processors, and so you cannot have a
different effect on each preset when in Multi mode.
The Master Effects settings assign the effect processors “globally” for all
presets to provide a way to use the effects in Multi mode. Detailed infor-
mation is presented in the Effects chapter (see Effects on page 173).
Effects Mode The FX Mode page enables or bypasses the effects. When the FX Mode is set
to “bypass,” the effects are turned off on a global scale. This includes Effects
programmed in the preset.
Effects Multi Mode
Control
The routing scheme for the two stereo effects processors provides a lot of
versatility. When in multi mode, you can “use master settings” which
applies the Master effects settings to all 16 MIDI channels.
If you want more control, you can use the “channel” setting which applies
the effects settings of the preset on a specified channel to all the other
channels. Changing the preset on the specified channel changes the effect.
If you are in Omni or Poly modes this parameter is disabled and the
message in parentheses explains that Halo is currently in Omni mode.

MIDI SysEx Packet
Delay
The MIDI SysEx Packet Delay command lets you specify the amount of
delay between MIDI SysEx packets going out of Halo so that your computer
sequencer can record this large chunk of data over a longer period of time.
On playback from the sequencer, the SysEx data will be fed more slowly
into Halo so that the its input buffer does not overflow, causing an error.
Many sequencers allow you to “Time Stamp” SysEx data as it is recorded.
This is the preferred mode for recording SysEx data.
The packet delay range is from 0 through 8000 milliseconds. A delay value
of zero allows full speed MIDI transfer. If you are experiencing data trans-
mission errors, try increasing the delay value until the problem disappears.

2. Place the sequencer into record mode, then Send MIDI Data.
To Receive MIDI SysEx Data from an External Sequencer:
Simply play back the sequence containing the SysEx data into Halo.
MIDI Mode MIDI Mode selects one of the three MIDI modes: Omni, Poly or Multi.
The MIDI Mode Change parameter specifies whether mode changes made
through an external MIDI controller are accepted or ignored.
The MIDI modes are as follows:
Omni
Responds to note information on all MIDI channels and plays the preset
currently displayed in the main screen.
Poly
Responds only to note information received on the currently selected MIDI
channel (on the preset selection screen) and plays that channel’s associated
preset.
Multi
Responds to data on any combination of MIDI channels and plays the
specific preset associated with each of the MIDI channels. You must select
multi mode for multitimbral operation.

Programming Basics
This chapter explains how Halo sounds are constructed and contains
important background information on how to create your own custom
presets.
Your initial involvement with Halo will most likely be using the existing
presets and selecting MIDI channels. While the factory presets are very
good, there are some things you will probably want to change eventually,
perhaps the LFO speed, the filter frequency or the attack time. You may also
want to make your own custom presets using complex modulation
routings. This module will do far more than you ever imagined and there
are whole new classes of sound just waiting to be discovered.
Each preset can consist of up to four instrument layers. Each of the four
layers can be placed anywhere on the keyboard and can be crossfaded or
switched according to key position, velocity, or by using a real-time control
such as a wheel, slider, pedal, LFO or envelope generator. A preset can also
be “linked” with up to 2 more presets creating additional layering or splits.
Halo has an extensive modulation implementation using two multi-wave
LFO’s (Low Frequency Oscillators), three multi-stage envelope generators
and the ability to respond to multiple MIDI controllers. You can simulta-
neously route any combination of these control sources to multiple desti-
nations.
There are 512 user locations (USER Banks 0-3) available to store your own
creations or edited factory presets. It’s easy and fun to edit or create your
own unique presets.

Modulation
Modulation To modulate means to dynamically change a parameter, whether it be the
volume (amplitude modulation), the pitch (frequency modulation), and so
on. Turning the volume control on your home stereo rapidly back and
forth is an example of amplitude modulation. To modulate something we
need a modulation source and a modulation destination. In this case, the
source is your hand turning the knob, and the destination is the volume
control. If we had a device that could turn the volume control automati-
cally, we would call that device a modulation source.
Turning the volume control back and forth on your home stereo is an example of
Amplitude Modulation.
Halo is designed so that each of the variable parameters, such as the
volume, has an initial setting which is changed by a modulation source.
Therefore in the case of volume, we have an initial volume that we can
change or modulate with a modulation source.
Two main kinds of modulation sources on Halo are Envelope Generators and
Low Frequency Oscillators. In the example above, an envelope generator
could be routed to automatically turn the volume control as programmed
by the envelope. Or, a low frequency oscillator could be routed to turn the
volume up and down in a repeating fashion.
Positive modulation adds to the initial amount. Negative modulation
subtracts from the initial amount.
Summing Nodes
All the modulation inputs on Halo are summing nodes. This means that
you can connect as many modulation sources as you want to an input (such
as Pitch or AmpVol). Modulation sources are simply added algebraically—
connecting two knobs one set to -100 and the other set to +100 yields a net
value of zero.

Modulation PatchCords
Random Sources Random modulation sources can be used when you want the timbre of the
sound to be “animated” in a random or non-consistent manner.
•Key Random 1 & 2 generate different random values for each layer
which do not change during the note.
•The White & Pink Noise Generators produce varying random values.
Both white and pink noise sources are low frequency noise designed
for control purposes. Either noise source can be filtered even more by
passing it through a lag processor.
•The Crossfade Random function generates the same random value
for all layers in a preset. This source is designed to be used for cross-
fading and cross-switching layers, although you may find other uses.
Modulation
PatchCords
When setting up modulation with the Halo, you define a modulation
source and a modulation destination. Then, you connect the source to the
destination using “PatchCords.” Halo’s PatchCords are connected in the
software. Halo has 24 general purpose PatchCords for each layer.
The controller Knobs
assignments printed on the front
panel are the system defaults.
You can change any of these
assignments using the Real-time
Controller Assignment page in
the MIDI menu (see page 94 for
details).
You can connect the modulation sources in almost any possible way to the
modulation destinations. You can even modulate other modulators. Each
PatchCord also has an amount parameter which determines “how much”
modulation is applied to the destination. The modulation amount can be
positive or negative. Negative values invert the modulation source.

Envelope Generators
Envelope
Generators
An envelope can be described as a “contour” which is used to shape the
sound over time in a pre-programmed manner. There are three envelope
generators per layer and all of them are the rate/level type.
This is how the rate/level (time based) envelopes work: When a key is
pressed, envelope starts from zero and moves toward the Attack 1 Level at
the Attack 1 Rate. As soon as it reaches this first level, it immediately begins
the next phase and moves toward the Attack 2 level at the Attack 2 rate. As
long as the key is held down, the envelope continues on through the Decay
1 and Decay 2 stages. If the key is still held when the envelope reaches the
end of Decay 2, it simply waits there for you to release the key. When you
release the key, the envelope continues into the Release 1 and Release 2
stages, stopping at the end of the Release 2 stage. Halo’s envelope gener-
ators provide great flexibility for programming both complex and simple
envelopes.
__
__ If two adjacent segments
have the same level in a “time-
based” envelope, the segment
will be skipped. Adjacent
segments must have different
levels for the rate control to work.
ADSR mode: To create
a standard ADSR envelope: Set
Atk1, Atk2 & Dcy1 Level to 100,
Rls 1 & 2 level to 0, and Atk2,
Dcy1, Rls2 Rates to 0. Program
Atk1, Dcy2 and Rls1 segments
as you wish. See page 201.
All three envelope generators have the six stages described above. The
Volume Envelope generator controls the volume of the voice over time.
The Filter Envelope generator is a general purpose envelope most often
used to control the filter frequency. Unlike the Volume Envelope, however,
the Filter Envelope can have a negative level value as well as a positive
level. There is also an Auxiliary Envelope generator which is a general
purpose envelope. The Auxiliary Envelope is identical to the Filter Envelope
and can have negative as well as positive levels. You can adjust the time of
each stage to create myriad envelope shapes, which in turn shape the
sound over time.
OO
OO By routing the Auxiliary
or Filter Envelopes to control the
pitch (PatchCords) you can
easily hear the shape of the
envelopes you are creating.
•Volume envelopes contour the way the volume of a sound changes
over time determining how we perceive that sound. For example, a
bell struck with a hammer is instantly at full volume, then slowly dies
away. A bowed violin sound fades in more slowly and dies away
slowly. Using Halo’s Volume Envelope, you can simulate the different
types of natural instrument volume envelopes by programming them
appropriately.

Envelope Generators
Tempo-based Envelopes
Tempo-based envelopes are based on Time which is controlled by the
Master Tempo (located in the Global menu). The Master Tempo rate scales the
time of the Tempo-based envelope segments. The Master Tempo can be set
to use an external MIDI clock so that the envelope times can be synchro-
nized to external sequencer or arpeggiator tempo changes. See page 82.
Envelope Repeat
The Envelope Generators can also be made to repeat. When the envelope
repeat function is On, the Attack (1&2) and Decay (1&2) stages will
continue to repeat as long as the key is held. As soon as the key is released,
the envelope continues through its normal Release stages (1 & 2).
Only the Filter and
Auxiliary Envelopes have the
repeating feature.
The diagram above show how the looping envelopes work. When the key is
pressed the envelope goes through its regular Attack 1, Attack 2, Decay 1
and Decay 2 stages. In non-looping mode, the envelope would hold at the
end of the Decay 2 stage until the key was released. In looping mode
however, it jumps back to the Attack 1 stage and repeats the first four
stages. It continues to loop through these four stages until the key is
released where it immediately jumps to the Release 1 stage.

Low Frequency Oscillators (LFOs)
Low
Frequency
Oscillators
(LFOs)
A Low Frequency Oscillator or LFO is simply a wave which repeats at a slow
rate. The Halo has two multi-wave LFOs for each channel. The LFO
waveforms are shown in the following illustration.
By examining the diagram of the LFO waveforms, you can see how an LFO
affects a modulation destination. The shape of the waveform determines
the result. Suppose we are modulating the pitch of an instrument. The sine
wave looks smooth, and changes the pitch smoothly. The square wave
changes abruptly and abruptly changes from one pitch to another. The
sawtooth wave increases smoothly, then changes back abruptly. The
sound’s pitch follows the same course. Controlling the pitch of an
instrument is an easy way to hear the effects of the LFO waves.
Try combining the
Pattern LFOs, or controlling the
amount of one with another, or
combining them with the clock
divisors.
Like the Auxiliary Envelope, LFOs can be routed to control any real-time
function such as Pitch, Filter, Panning, or Volume. A common use for the
LFO is to control the pitch of the sound (LFO -> Pitch). This effect is called
vibrato and is an important performance effect. Many presets use this
routing with the modulation wheel controlling “how much” LFO
modulation is applied. Another common effect, Tremolo, is created by
controlling the volume of a sound with the LFO (LFO -> Volume).

Programming Basics
Clock Modulation
You might use the LFOs to add a slight bit of animation to the sound by
routing the LFO to control the filter. For this effect, set the LFO “amount”
low for a subtle effect.
When a PatchCord amount is a negative value, the LFO shape is inverted.
For example, inverting the sawtooth wave produces a wave that increases
abruptly, then smoothly glides down.
Clock
Modulation
You can use the Master Clock as a modulation source, to trigger the Filter or
Auxiliary Envelope generators, trigger Sample Start, synchronize the LFOs,
or directly as a square wave modulation source. The Clock source is
available in eight divisions (octal whole note, quad whole note, double
whole note, whole note, half note, quarter note, eighth note, sixteenth
note). You can use the different rates separately or in conjunction to create
complex “synchro-sonic” rhythm patterns. You can also use a MIDI Clock
as the Master Clock to synchronize to an external MIDI device such as a
drum machine or sequencer. (See Master Tempo in the Global menu.)
Envelopes are triggered
on the positive going edge of the
clock. LFOs are triggered on the
negative going edge of the clock.
Clocks are routed exactly like the other modulations sources using the
PatchCords. The PatchCord Amount MUST be positive (+) for the clock to
pass. By modulating the PatchCord Amount, you can route the divided
clocks using real-time controllers or other modulation sources.
When an LFO is triggered by a clock, the LFO wave resets to zero every time
the clock wave goes low. If the LFO rate is close to the clock rate, the LFO
virtually synchronizes with the clock. If the two rates are far apart, the
waveform of the LFO will be mildly or radically altered.
The tempo of the master
clock is set in the Global menu.
LFO Trigger causes the LFO to reset each time the clock waveform goes low.

Clock Modulation
LFOs can also be perfectly synchronized with the clock at any of 25 note
divisions. This allows you to create very cool “synchro-sonic” effects that
work perfectly at any tempo. Choosing one of the note divisors in the LFO
rate screen selects the synced LFO function.
There are many possibilities for clock modulation and retrigger. For
example, you can create a repeating six segment curve of any shape by
triggering the Filter or Auxiliary Envelope generators with the clock. A few
other possibilities are listed below.
•Turn different voice layers on and off using different clock divisors.
•Switch between Auxiliary and Filter Envelope retriggering using a
slider or footswitch.
•Retrigger LFOs or Envelopes using noise or other LFOs to create
random or semi random effects.
•Alter the LFO waveform by modulating the rate of a triggered LFO.
•Route multiple clocks with different divisors to the same destination
(such as pitch) to create complex patterns. (Hint: Adjust the PatchCord
Amounts.)
Adding these two clocks together in equal amounts produces a stairstep waveform.
Adding multiple clocks with unequal amounts produces complex repeating patterns.

Modulation
Destinations
The PatchCords section of the Preset Edit menu is where you connect
sources to destinations. Each PatchCord has an amount associated with it
which controls how much modulation is applied.
The PatchCords screen above and the diagram below show how
modulation sources are connected to destinations. The modulation sources
can control any of the destinations in the layer.
All the modulation
destinations are summing
nodes. This means that you can
connect as many modulation
sources as you want to a
destination. Modulation sources
are simply added algebraically
— connecting two sources, one
with a value of -100 and the
other with a value of +100 yields
a net value of zero.
•Note-on modulation sources, such as key, velocity and gate output a
single value at note-on time. Realtime modulation sources such as
LFOs, envelope generators and modulation wheels output
continuously changing values.
The possible modulation routings are completely flexible as shown in the
diagram above. Multiple sources can control the same destination, or a
single source can control multiple destinations.

Modulation processors are devices which can modify modulation sources

Switch
Outputs a digital “1” when the input is greater than “0”.
Summing Amp
Lets you add several modulation signals together before applying them to a
destination. This processor can save PatchCords when routing the output
to multiple destinations.
Lag Processors
Slows down rapid changes in the input signal. The output “lags” behind the
input at a pre-programmed rate. There are two lag processors, Lag 0 and Lag
1. Lag 1 has a longer lag time than Lag 0.

This function inverts negative input values and outputs only positive
values. This device is also called a full wave rectifier.

Processors start working as soon

Layer Modulation Processors
take effect only when a key is

Like the Layer Lag processors (described on page 109) the Preset Lag slows
down rapid changes in the input signal. The output “lags” behind the input
at a pre-programmed rate. Unlike the layer level lag processors, the preset lag
takes effect as soon as the preset is selected. In contrast, the layer level lag
processors begin acting only after a keyboard key has been depressed. The
Preset Lag also has a Lag Amount input which controls the lag time. Positive
lag amounts increase the lag time. A MIDI controller (front panel knob) is
commonly used to control lag amount.
The preset lag can be used to “spin-up” and “spin-down” an LFO which
controls some other effect, perhaps left/right panning, pitch, or the filter. A
MIDI footswitch could be used as the input to the lag which acts to slow
down the instantaneous change of the switch. The slowly changing output
value is then routed using a layer patchcord to crossfade between layers or
change the speed of an LFO.

The preset ramp instantly resets when all notes have been released and the

(+ or -) determines if the ramp will be positive or negative going. The value

small values produce slow ramps. Multiple inputs can be connected to the
ramp rate (just like all the other destinations in Halo).
The patch below shows an application for the Preset Ramp which generates
an adjustable decay envelope ONLY on the first note played to bring in the

Preset Modulation Processors
Using the
Modulation
Processors
Modulation processors are inserted into a modulation routing as shown in
the following diagram.
The modular analog synthesizers of yesteryear were incredibly flexible,
partly because processing devices could be connected in any order.
Modulation processors are designed according to this modular concept.
They can be linked and used in a wide variety of ways limited only by your
imagination. Consider the following example:
The patch illustrated above is programmed by setting the PatchCord
screens as shown below.
This particular modulation shifts the overall pitch up a fifth when the key
velocity exceeds 64. Velocities below 64 play at normal pitch. Notes with
velocities of 64 and above are raised a perfect fifth. The Velocity “~” source
scales the played velocity around zero. In other words, low velocities (below
64) will have negative values and high velocities (64 and above) will be
positive. A velocity of 64 would be zero. The Switch module only outputs a
“1” if the input value is greater than zero. This digital “1” value can be
scaled through the attenuator on the PatchCord to raise or lower the pitch
by any amount. In this case, a scaling value of +22 raises the pitch by a
perfect fifth. The amount of the PatchCord on the input to the switch is
unimportant because ANY velocity value equal or greater than 64 will flip
the switch. If the input PatchCord amount were a negative value however,
the action of the velocity would be reversed and velocities less than 64
would raise the pitch and velocities equal or greater than 64 would play the
original pitch.

But what if you want the velocity switch point to be something other than
64? Thanks to modulation processors, it can be done. Here's how.
Connect the DC level to the input of the switch along with the velocity
value. Note that more than one modulation source can be applied to the
input of a processor.
DC offset adds a fixed value based on the PatchCord Amount setting. If
applied to the switch along with the velocity, it changes the velocity value
required to trip the switch. By setting the DC amount to a negative
amount, higher velocity values are required to trip the switch. Setting the
DC value to a positive value would bring the velocity switch point down.

More Examples To derive a smooth random function you could route the Pink Noise
generator through one of the Lag Processors. A smooth random wave is
useful in small amounts to add a degree of natural variation to timbre when
routed to filter cutoff. Normal pink noise is low pass filtered audio
frequency noise with a 3 dB/octave slope to give equal energy per octave.
Halo pink noise is actually more like very low frequency filtered noise, but
it is perfect for use as a random control source.
The Quantizer can generate interesting whole-tone scales when envelope
generators or LFOs are routed to the input. The quantizer turns a smoothly
changing input signal into a series of steps. By routing the output of the
quantizer to Pitch and adjusting the PatchCord amounts, you can control
both the number of steps and the pitch interval of each step.
The input PatchCord amount controls how many steps will be generated.
With a sawtooth wave (LFO+) feeding the input and the PatchCord amount
set to 100%, sixteen steps are generated. The output PatchCord amount
controls the size (or interval) of the steps.
Try setting up the following patch exactly as shown below using your
favorite preset as a starting point.

To understand how a filter works, we need to understand what makes up a
sound wave. A sine wave is the simplest form of sound wave. Any
waveform, except a sine wave, can be analyzed as a mix of sine waves at
specific frequencies and amplitudes.
Any waveform can be analyzed as a mixture of sine waves.
One way to represent complex waveforms is to use a chart with frequency
on one axis and amplitude on the other. Each vertical line of the chart
represents one sine wave at a specific amplitude and frequency.

What is a Filter? Most sounds are complex waves containing many sine waves of various
amplitudes and frequencies. A filter is a device which allows us to
remove certain components of a sound depending on its frequency. For
example, a low-pass filter lets the low frequencies pass and removes only the
high frequencies as illustrated in the following diagram.
A filter that lets only the high frequencies pass is called a high-pass filter as
illustrated in the following diagram.

Dynamic Filters
A filter which only lets a certain band of frequencies pass is called a
band-pass filter.
A notch filter is just the opposite of a band-pass filter and is used to
eliminate a narrow band of frequencies.
Another control found on traditional filters is called Q or resonance. A
lowpass filter with a high Q emphasizes the frequencies around the cutoff
frequency. The following chart shows how different amounts of Q affect
the low-pass filter response. In terms of sound, frequencies around the
cutoff tend to “ring” with high Q settings. If a filter with high Q is slowly
swept back and forth, various overtones are “picked out” of the sound and
amplified as the resonant peak sweeps over them. Bells and gongs are real
world examples of sounds which have a high Q.

Dynamic Filters
Another characteristic of a filter is the number of poles it contains. Tradi-
tional synthesizer filters were usually either 2-pole or 4-pole filters. The
Halo has selectable 2, 4, and 6-pole low-pass filters. The number of poles in
a filter describes the steepness of its slope. The more poles, the steeper the
filter's slope and the stronger the filtering action. The tone controls on your
home stereo are probably one-pole or two-pole filters. Parametric equalizers
are usually either two-pole or three-pole filters.
In terms of vintage synthesizers, Moog and ARP synthesizers used 4-pole
filters, Oberheim and Eµ synthesizers were famous for their 2-pole filter
sound.
Using a filter, we have a way to control the harmonic content of a sound.
As it turns out, even a simple low-pass filter can simulate the response of
many natural sounds.
For example, when a piano string is struck by its hammer, there are initially
a lot of high frequencies present. If the same note is played softer, there are
fewer high frequencies generated by the string. We can simulate this effect
by routing keyboard velocity to control the low-pass filter. The result is
expressive, natural control over the sound.
If you use an envelope generator to control the cutoff frequency of a filter,
the frequency content can be varied dynamically over the course of the
note. This adds animation to the sound as well as simulates the response of
many natural instruments.

Parametric Filters A more complex type of filter is called a parametric filter or Swept EQ. A
parametric filter allows control over three basic parameters of the filter. The
three parameters are: Bandwidth, Frequency and Gain. The Bandwidth allows
you to select the width of the range of frequencies to be boosted or cut, the
Frequency defines the center frequency of the bandwidth, and the Gain
parameter either boosts or cuts the frequencies within the selected band by
a specified amount. Frequencies not included in the selected band are left
unaltered. This is different from a band-pass filter which attenuates
(reduces) frequencies outside the selected band.
The parametric filter is quite flexible. Any range of frequencies can be either
amplified or attenuated. Several parametric sections are often cascaded in
order to create complex filter response curves.
If four parametric filter sections were cascaded, it would be possible to
create the following complex filter response.
Many natural instruments have complex resonances which are based on
their soundboard or tube size. The resonance shown above would be impos-
sible to create using a normal synthesizer filter.

The Z-Plane Filter A Z-plane filter is a filter which can change its function over time. In a
Z-plane filter, we start with two complex filter types and interpolate
between them using a single parameter. See the following diagram.
The Z-plane filter has the unique ability to change its function over time.
Filters A and B represent two different complex filters or “frames.”
Changing a single parameter, the Morph, changes many complex filter
parameters simultaneously. Following along the Morph axis you can see
that the filter response smoothly interpolates between the two filters. This
is the essence of the Z-plane filter. Through the use of interpolation, many
complex parameters are condensed into one manageable entity.
Consider, as an example, the human vocal tract, which is a type of complex
filter or resonator. There are dozens of different muscles controlling the
shape of the vocal tract. When speaking, however, we don't think of the
muscles, we just remember how it feels to form the vowels. A vowel is really
a configuration of many muscles, but we consider it a single object. In
changing from one vowel to another, we don't need to consider the
frequencies of the resonant peaks. You remember the shape of your mouth
for each sound and interpolate between them.
This Z-plane filter sweep can be controlled by an envelope generator, an
LFO, modulation wheels or pedals, keyboard velocity, key pressure, and so
on. In fact, any of the modulation sources can control the Z-plane filter.
Because creating the complex filtering is difficult and very time consuming,
we have created 50 different filters and installed them permanently in ROM
for your use. You simply select and use the filters in a manner similar to
choosing an instrument. Because there are so many types of instruments
and filters to choose from, the number of possible permutations is
staggering.

Signal Flow
Signal Flow Going back to the Signal Path diagram for a single channel we can
reexamine the complete signal path.
Instrument
This is the sampled sound wave. The pitch of the instrument can be
modulated by any modulation source. The sample start point can be
changed only at the time the note is played.
Z-Plane Filter
The Z-Plane Filter is used to shape the harmonic content of an instrument.
The filter envelope is commonly used to shape the harmonic content
dynamically over time but the filter frequency can be modulated by any
source. The Q parameter can be modulated only at note-on time. There are
50 types of filters available. See “Halo Filter Types” on page 148 for a
complete list of the filters.
Digitally Controlled Amplifier (DCA)
Together with the Volume Envelope, the DCA is used to shape the volume
contour of a sound. The DCA can be controlled by any modulation source.
Velocity is often used as a modulation source for the DCA so that the harder
you play, the louder the sound becomes.
Pan
Adjusts the balance of sound to the left and right channels. Pan can be
modulated by any modulation source.

MIDI Channels & Real-time Controls
MIDI Channels
&
Real-time
Controls
The MIDI real-time controllers may seem confusing at first, but they are
really very simple once you understand them. You already know that there
are 16 MIDI channels per MIDI cable. Each MIDI channel uses three basic
types of messages; note on/off, preset changes, and continuous controller
messages. Halo can also send real-time control information, which simply
means control occurring in real-time or “live.” Real-time control sources
include such things as controller knobs, pitch wheels, modulation wheels,
control pedals and aftertouch. These are used to add more expression or
control.
The front panel control knobs send out real-time controller information on
separate continuous controller numbers. There is a set of 32 continuous
controller numbers for each MIDI channel. Some continuous controllers,
such as modulation wheel, volume, and pan have standardized numbers.
For example, volume is usually sent on continuous controller #7. The front
panel controller knobs on are pre-programmed to control the Halo.
The following MIDI
controls are automatically routed
in Halo:
Pitch Wheel pwh
Modulation Wheel 01
Pedal 04
Volume 07
Pan 10
Expression 11
Any MIDI controller can be routed to any modulation destination. First,
you have to know which controller numbers your keyboard transmits. Most
modern MIDI keyboards let you select a controller number for each control
on the keyboard. For example, it may let you select a number from 0-31 for
the data slider. The realtime controller numbers that the keyboard
transmits must match the numbers Halo is receiving, otherwise nothing
will happen when you move the controls.
Suppose you wanted to send the four data knobs on another keyboard via
MIDI to Halo. Halo can handle up to 16 MIDI controllers (A-P) of your
choosing. “MIDI A-P” are simply names for the internal connections that
link external MIDI continuous controllers to the PatchCord section of Halo.
There are two parts to the connection. First, MIDI controller numbers are
assigned to the letters A-P in the Controllers menu. Next, the letters A-P are
connected to synthesizer control parameters in the PatchCord section of
the Preset Edit menu. The PatchCord Amount scales the amount of each
controller by a positive or negative value.
The factory presets have the MIDI A-P controls connected to standard
synthesizer functions (marked on the front panel). By choosing any four of
the 16 standard functions, the four sliders on your keyboard will work the

MIDI A-P are internal connections which simultaneously carry front panel controller knob
data and MIDI continuous controller data.
The front panel controller knobs work just like MIDI real-time controllers.
The four controller knobs can be assigned to the first 12 letters A-L. The
front panel knob and incoming MIDI controller messages assigned to that
letter, both control the same parameter that you select in the PatchCord
screen. Letters M-P can be used to route 4 more external MIDI controllers.

Bank Select
Commands
When the original MIDI specification was developed, no synthesizer had
more than 40 preset locations. At that time being able to select up to 128
presets didn’t seem like much of a limitation. So it was that the original
MIDI specification provided for the selection of up to 128 presets.
Musicians wanted MORE presets and so the MIDI specification was later
amended to include Bank Select Commands. It was decided that Bank
Select Commands would use Continuous Controllers 0 and 32 to allow the
selection of up to 16,384 banks of 128 presets (over two million presets).
Because Bank Selects are implemented using Continuous Controllers, the
Bank Selections can be made per channel. (This is getting better and better.)
For each MIDI channel, you can select any of 16,384 banks and then one of
the 128 presets in the bank. Of course no synthesizer has 16,384 banks
(yet), but hey, it’s nice to know it’s possible (for that really BIG project).
Continuous Controller (CC) 0 is the MSB (most significant byte) and CC 32
is the LSB (least significant byte). Normally you send both the MSB and LSB
controllers to implement a bank change.
When you press the
Audition button, the Bank Select
MSB and LSB are displayed on
the top line of the display.
Halo remembers the MSB and the LSB that were last sent (or last changed
from the front panel). For example, if you have already set the Bank MSB to
04, you need only send the LSB to change banks within the Halo sound set.
See the MIDI Bank Select chart below.
The selected bank remains selected until you change it (either via MIDI or
by changing the bank from the front panel). Standard MIDI Program
Change commands select from 128 presets within the selected bank.

The routing can be performed according to MIDI channel from the Mix
Output screen in the Global menu. Simply assign each channel to the
desired output.
To route a particular preset to a Send, first go to the Mix Output screen in
the Global menu and set the MIDI channel to “use preset”.
Next set the Mix Output routing in the preset to the desired output (for
each layer). Yes, you can send each layer to a different send if you want.
By sending different amounts of presets to the effects, subtle or striking
effects can be achieved using the two effect processors. This feature allows

Defining the Velocity Crossfade Range
The Fade fields define the velocity crossfade range for the currently selected

value. The second defines the Fade Out range for the high velocity value.
With soft playing, Layer 1 sounds. As you play harder, Layer 1 gradually fades out and
Layer 2 fades in. When the keyboard is played hard, Layer 3 plays.
To Set Up a Velocity Crossfade Between Layers:
Set the velocity fades so that layer 1 fades out with higher key velocity,
while layer 2 fades in. At a velocity of 64, the two sounds are equal volume.
You may want to adjust the fade in and fade out points to achieve a natural
sounding crossfade. These parameters vary depending on the sounds.

Defining the
Real-time Crossfade
Range
The Real-time Crossfade window lets you control the volume of the four
layers using a real-time controller such as a front panel knob, a pedal or an
LFO or Envelope generator. The controller is defined by the PatchCord
parameter (see “PatchCords” on page 157).
The Fade fields define the crossfade range in velocity for the currently
selected layer. The first Fade field defines the Fade In amount for the low
Real-time Control value. The second defines the Fade Out amount for the
high Real-time Control value. The Fade value range is from 0 to 127.
After the Ranges and Fades have been adjusted for each layer in the Real-
time Crossfade screen, you must assign a real-time controller to RTXfade
(Real-time Crossfade) on each Layer in the PatchCord screen. Set the
PatchCord Amounts to +100.
To Set Up a Real-time Crossfade Between Two Layers:
As the real-time control (knob, pedal, LFO, etc.) is increased, Layer 1 fades
out as Layer 2 fades in. This example only uses two of the possible four
layers. Refer to the screen diagrams below.

5. Define the High and Low range of each Layer. In this example the entire
range of 0-127 is used.
6. Define the Fades for each Layer. This is just an initial setting. The Range
and Fade parameters may have to be adjusted later to get a smooth

7. Press Home/Enter and use the data entry control to advance to the
PatchCord page. Select Layer 1.
8. Select the modulation source for the crossfade (knob, pedal, LFO,
Envelope) and set the destination to RTXfade. Set the Cord Amount to
+100.
9. Select Layer 2. Select the same source and destination for the crossfade
and set the Cord Amount to +127.
10. Play the keyboard while adjusting the real-time controller. Go back to
the Real-time Crossfade screens to fine tune the crossfade if necessary.
Decreasing the fade size will narrow the region where both layers are
sounding.
To Randomly Cross-Switch Between Four Layers:
In certain situations, you may want to switch between several layers
randomly. Crossfade Random is a modulation source specifically designed
to handle this situation. Unlike the other random sources, Crossfade
Random generates one random number for all layers each time a key is
pressed.
To set up a four layer Cross-Switch, simply assign each of the four layers to
a different Real-time Crossfade range, then assign XfdRnd to RTXfade in
the PatchCords for each layer.

Transposing the Instrument
8. That’s it! Now set each Layer up the way you want. Try radically
different instruments, filter settings, or tunings. Or you can make each
layer just slightly different for a more natural effect. Try adjusting the
Fades or overlapping the ranges if you want more than one layer to play
at once.
Transposing the
Instrument
The Transpose parameter lets you transpose the key of the current layer’s
Instrument. Transpose works by shifting the keyboard position in semitone
intervals relative to middle C. Use this parameter to transpose different
layers apart by semitone intervals. For example, by transposing one layer by
+7 semitones, it will track other layers at a perfect fifth interval.
The range of transposition is -36 to +36 semitones.

Tuning
Tuning The Tuning parameter changes the pitch of the key in semitone and 1/64
semitone intervals.
Use the Coarse field to shift the tuning by semitone intervals. Use the Fine
field to shift tuning by 1/64 semitones (or 1.56 cents) intervals.
Background: Transpose vs. Coarse Tuning
Transpose works by shifting the keyboard assignment of the Instrument (as
if you were sliding the keyboard up and down with the Instrument
remaining in the same position). Coarse Tuning keeps the instrument
placement on the keyboard and actually tunes the samples up using a
digital process called interpolation. Use Course Tuning on drum instru-
ments to change the pitch while keeping sample placement constant.
Coarse Tuning can also be useful to slightly change the timbre of the
instrument.
Amplifier This parameter sets the initial volume and pan position of the current layer.
These values can be changed using any Real-time Controller set up in the
PatchCords. The value range for the volume is from -96 dB to +10 dB. 0 dB
is the default setting. Routinely turning the volume up to +10 dB is not
recommended because it doesn’t allow other modulation sources to
increase the volume further.
This field determines the initial Pan value for the current layer. The value
range for Pan is from 64L to 0 (left) and 0 to 63R (right). Pan adjusts the
volume into the left and right output channels relative to the Pan setting in
the main Preset Select screen (see “Channel Pan” on page 39). So, if you, for
example, set the Pan value in the Preset Select screen to 64L and set this
Pan value to 63R, the actual pan amount would be 0 as these two pan
parameters are relative to each other.

Volume Envelope
Volume Envelope An envelope can be described as a “contour” which is used to shape the
sound over time. The Volume Envelope controls the volume of the sound in
the current layer over time. The way the volume of a sound evolves has a
profound effect on how we perceive the sound.
Each instrument has its own Factory preset Volume Envelope setting. The
Volume Envelope allows you to program your own envelope settings.
Selecting the Mode
The Mode field determines whether the layer will use the instrument’s
default envelope (Factory) or use the user-programmed Volume Envelope.
There are three mode options and repeat.
OO
OO Factory Mode is useful
for Instruments containing
multiple drums, since each drum
can have its own envelope
settings.
A factory drum kit envelope
actually contains a separate
envelope for every voice on every
key instead of a single global
envelope.
•Factory: Uses the factory preset envelope contained in each instrument.
If you select the “Factory” mode, the Volume Envelope parameters are
disabled and the factory defined settings are used instead.
•Time-based: Defines the Volume Envelope rates from 0 to 127 (approxi-
mately 1 ms to 160 seconds). The Master clock has no affect on time-
based rates.
__
__ If two adjacent segments
have the same level in a “time-
based” envelope, the segment
will be skipped. Adjacent
segments must have different
levels for the rate control to work.
•Tempo-based: The Volume Envelope times vary based on the master
tempo setting. Note values are displayed instead of a number when the
time corresponds to an exact note value. Tempo-based envelopes are
useful when using external sequencers and arpeggiators because the
envelope rates compress and expand according to the Master Tempo set-
ting, keeping the envelopes in sync with the sequence or arpeggio.
Tempo-based envelope rates change according to the Master Tempo rate.

Volume Envelope
Defining the Volume Envelope
See the Programming
Basics section of this manual for
detailed information about how
the Envelopes work.
The Volume Envelope controls the volume of the layer over time. The
Volume Envelope has six stages to the contour: Attack 1, Attack 2, Decay 1,
Decay 2, Release 1 and Release 2. When a key is pressed, the Envelope goes
through the first four stages. If you continue to hold down the key, the
envelope holds at the Decay 2 level. When the key is released, the envelope
continues through the Release stages ending at the Release 2 level.
As soon as the Attack 1 level is reached, the Attack 2 phase begins. When
the Attack 2 Level is reached, the Decay 1 phase begins. When the key is
released, the envelope immediately jumps to the Release 1 stage, then the
Release 2 stage finally ending at the Release 2 level.
If you have selected the factory mode, the Volume Envelope parameter
screen looks like the following illustration.
__
__ If the Release 2 level is set
at a value other than zero, the
note will continue to sound after
the key is released. This might be
useful for drone effects, but the
channel won’t stop sounding
until all channels are used up.
On the Volume Envelope, levels can only be set to positive values.
The value range is from 0 to +100.

Chorusing the Layer
Chorusing the Layer Chorusing “thickens” the sound by doubling the sound in stereo and then
detuning it. Every layer with chorus turned on uses twice the polyphony
for that layer.
__
__ WARNING: Because it
works by doubling instruments,
Chorusing halves the number of
notes you can play.
The first field in this screen turns Chorus On or Off and allows you to adjust
the amount of detuning (1 to 100%). The Width parameter controls the
stereo spread. 0% reduces the chorus to mono and 100% provides the most
stereo separation.
Sound Start Offset
and Delay
Sound Start sets where the instrument begins playing when you hit a key.
Setting the Start Offset amount to “0” plays the sample from the beginning.
Higher values move the Sample Start Point further into the sample toward
the end. There is also a PatchCord source which can be used to change the
Sound Start point at note-on time.
Controlling the Sound Start using Key Velocity (< Amt -) brings in the attack of the wave
only when you play hard. This is especially effective with percussion instruments.
Delay defines the time between when you hit a key (note-on) and the onset
of the current layer’s note and the start of the envelopes (if applicable).
Delay values below zero are Tempo-based values, meaning the time is based
on the Master Tempo setting. Note values are displayed by adjusting the
Delay Time value below zero. The sound will be delayed by the selected
note value based on the master clock.

This function turns keyboard transposition On or Off for the current layer.
With Nontranspose “on,” the keyboard will not control the pitch of the

sound effects which you may not want to track the keyboard.
Solo Mode Provides the playing action of a monophonic instrument such as a lead
synthesizer by preventing more than one note from sounding at once.
There are eight different solo modes provided. Try setting up different
layers with different solo mode and glide rates or combine solo mode with
polyphonic playing modes.
OO
OO In order to define a
monophonic glide (see the
Portamento parameter), you
must be in Solo mode.
The Solo modes are:
Multiple Trigger: Last note priority. No key-up action. Retriggers
envelopes and samples when a key is pressed.
Melody (last): Last note priority. No key-up action.
First solo note: Envelopes start at Attack segment from zero. Samples
start at the beginning.
If previous note is releasing: Envelopes start at Attack segment, but from
current level. Samples start at the beginning.
When playing “Legato”: Envelopes continue from current segment and
level. Samples start at the loop or the beginning if unlooped.
Melody (low): Same as Melody (last), but with low note priority. Newly
played keys which are higher than the lowest solo key held do not sound.
Melody (high): Same as Melody (last), but with high note priority. Newly
played keys which are lower than the highest solo key held do not sound.
Synth (last): Similar to Melody (last) but this mode has key-up action.
When you release the currently sounding solo key while holding other keys
down, the highest held solo key sounds in a Legato fashion.

highest held solo key sounds in a Legato fashion.
Fingered Glide: Same as Synth (last), except that Glide is disabled when
playing Staccato, enabled when playing Legato.
Assign Group Use the Assign Group parameter to assign a certain number of channels to
each layer. By assigning all voices in the preset to assign groups, important
parts are protected from being “stolen” by more recently played keys. Or
you can assign a voice, such as an open high hat, to a mono channel so it is
cancelled by a closed high hat on the same mono channel. Layers rotate
within their assigned “bin” of channels, not interfering with other bins.
The modes are:
Poly All: Notes are played polyphonically with dynamic channel
assignment using all 64 channels.
Poly 16 A-B: Two bins of 16 channels each. Notes are played polyphoni-
cally with dynamic channel assignment using no more than 16 channels.
Poly 8 A-D: Four bins of 8 channels each. Notes are played polyphonically
with dynamic channel assignment using no more than 8 channels each.
Poly 4 A-D: Four bins of 4 channels each. Notes are played polyphonically
with dynamic channel assignment using no more than 4 channels each.

Glide
Glide Glide creates a smooth transition from one note to the next instead of the
normal instantaneous change in pitch when a new key is pressed. This
effect is commonly heard on slide guitars, synthesizers and violins.
The front panel Glide Button LED comes on when the any layer of the
current preset has a glide rate greater than 0.000 seconds (regardless of if a
PatchCord is connected or not). Pressing the button turns the LED and
glide off. Pressing the front panel glide button when all layers are set to a
glide of 0.000 turns glide on with a rate of 0.142 seconds/octave.
The Glide Rate parameter defines the time it takes to glide to the new pitch
(the larger the value, the slower the glide rate) The glide rate value range is
from 0 through 32.738 seconds (zero means off).
The Glide Curve describes how the glide accelerates as it slides between
notes. Because of the ear’s non-linear response to pitch, a linear glide
sounds slow at the beginning and speeds up toward the end. Exponential
curves actually sound smoother and more linear. Eight exponential curves
are provided. Choose one that suits your style.
Glide can be either polyphonic or monophonic depending of the state of
Solo Mode.
To Set up a Glide Rate Knob:
1. Set at least one layer to the minimum setting of 0.002 sec/oct. (This
forces the Glide LED to come on.)
2. Connect the MIDI controller of your choice to Glide Rate on the layers
you’d like to glide. Adjust the Cord Amount for the desired range.
3. Disconnect the MIDI controller from whatever else it was connected to
before you started mucking about.
4. The Glide button turns Glide on/off and the knob controls the rate.

Z-Plane Filters
Z-Plane Filters A filter is a device which changes the output of a signal (sound) by
removing certain elements of the signal based on the frequency and
amplitude. The “Order” of a filter defines the number of filter elements it
contains. The more elements, the more complex the filter.
Halo contains 50 different types of E-MU’s celebrated Z-plane filters. In
addition to the standard Low pass, High pass and Band pass filters, Halo
contains Swept Octave Equalizers, Phasers, Flangers, Vocal Formant Filters,
and digital models of classic synthesizer filters.
In the filter chart below you will notice that the “Order” of the filters varies
from 2 to 12 order. Higher order filters have more sections and can produce
more complex formants. Halo can produce 128 filters of up to 6th order or
64 filters of 12th order complexity. Therefore, if you decided to use all 12th
order filters, Halo would be limited to 64 voices.

Filter Envelope
Filter Envelope The Filter Envelope is normally used to control the filter frequency and has
six stages. Unlike the Volume Envelope, the Filter Envelope must be
patched to the Filter Frequency using a PatchCord. In this respect, it can be
thought of as a general purpose envelope generator which is normally
patched to control the filter. The Filter Envelope Levels can be negative as
well as positive.
There are three mode options:
•Time-based: Defines the Filter Envelope rates from 0 to 127 (approxi-
mately 1 ms to 160 seconds). The Master clock has no affect on time-
based rates.
•Tempo-based: The Filter Envelope times vary based on the master tempo
setting and are displayed in values such as 1, 2, 3, etc. Note values are
displayed instead of a number when the time corresponds to an exact
note value. Tempo-based envelopes are useful when using arpeggiators
and sequencers because the envelope rates compress and expand accord-
ing to the Master Tempo setting, keeping the envelopes in sync with the
music. See the illustration on page 104.
•Envelope Repeat: The Envelope Generators can also be made to repeat.
When the envelope repeat function is On, the Attack (1&2) and Decay
(1&2) stages will continue to repeat as long as the key is held. As soon as
the key is released, the envelope continues through its normal Release
stages (1 & 2). For more information see page 104.
To Turn on Envelope Repeat:
1. Move the cursor until it is underneath the Mode field as shown below.
2. Turn the data entry control clockwise. The lower line changes to:

Defining the Filter Envelope
See the Programming
Basics section of this manual for
detailed information about how
the Envelopes work.
The Filter Envelope controls the filter frequency of the layer over time. The
Envelope has six stages to the contour: Attack 1, Attack 2, Decay 1, Decay 2,
Release 1 and Release 2. When a key is pressed, the Envelope goes through
the first four stages. If the key continues to be held, the envelope holds at
the Decay 2 level. When the key is released, the envelope immediately
jumps to the Release 1 stage, then the Release 2 stage finally ending at the
Release 2 level.
The default PatchCord
settings connect the Filter
Envelope to Filter Frequency but
the envelope can be routed to
any real-time control destination
using a PatchCord.
Auxiliary Envelope The Auxiliary Envelope is a supplementary general purpose envelope that
can be routed to any real-time control destination in the PatchCords. It is
identical to the filter envelope generator. See “Filter Envelope” on page 151
for full details.

Low Frequency Oscillators (LFOs)
Low Frequency
Oscillators (LFOs)
A Low Frequency Oscillator or LFO, is simply a wave that repeats at a slow
speed. Halo has two LFOs per layer identified on the display as LFO1 and
LFO2.
An LFO can be routed to any real-time control destination using a
PatchCord. LFOs have a myriad of uses, some of which probably haven’t
been thought of yet. The following examples show a few common uses.
•Control the pitch of the sound (LFO -> Pitch). This effect is called
“vibrato” and is an important performance tool. Many presets use this
routing with the modulation wheel controlling “how much” modula-
tion is applied.
•Create a “tremolo” effect by routing the LFO to control the volume
(LFO -> AmpVolume).
•Add a bit of animation to the sound by routing the LFO to control the
filter. Set the PatchCord amount low for a subtle effect.
The LFOs have five parameters: Shape, Sync, Rate, Delay and Variation.
Shape
LFO waveforms have different shapes. The shape of the waveform deter-
mines the effect of the LFO. LFOs have traditionally been used to add
vibrato or repeating movement to a sound. These new shapes offer a lot of
new programming possibilities.
If you modulate the pitch of an instrument, it’s easy to visualize the shape
of the waveform. For example, the sine wave has a smooth, rolling shape
that changes the pitch smoothly. The square waveform changes between
two pitches abruptly. A sawtooth waveform increases the pitch smoothly,
then abruptly changes back down. The available waveforms are shown
below.
L1 LFO1 SHAPE SYNC
sawtooth key sync
154 ENSONIQ
Preset Edit Menu
Low Frequency Oscillators (LFOs)
Sync
The Sync field specifies whether the LFO is synchronized to a key stroke or
is Free Running. Key Sync starts the LFO wave at the beginning of its cycle
each time you press a key on the controller. In Free Run mode, the LFO
wave begins at a random point in its cycle each time you press a key on the
controller.
Rate
The Rate field determines the LFO speed in absolute frequency rate values
or tempo-based note values. All values equal to or greater than zero specify
absolute frequency values from 0.08 Hz to 18.14 Hz.
LFO Tricks & Tips:
•The Random LFO wave is truly
random and is different for
each voice and layer.
•The Pattern (Pat) waveforms
will sound the same on
different layers and voices.
•Sine + Noise is very useful for
simulating trumpet and flute
vibrato.

Low Frequency Oscillators (LFOs)
Values less than zero specify tempo-based rates. If you modulate the rate of
a tempo-based LFO, the rates will jump between the tempo-based note
values with each PatchCord increment of “1”. As an example: if the LFO
rate was set to 8/1 and you patched the Mod Wheel to control rate with a
PatchCord amount of +1, turning the Mod Wheel to maximum would
change the LFO rate to 4/1d. Refer to the chart below.

Delay
The Delay parameter defines the amount of time between hitting a key on
the controller and the onset of the LFO modulation. Delay can be used to
simulate an effect often used by acoustic instrument players where the
vibrato is brought in only after the initial note pitch is established. The
following illustration demonstrates how delay works.
All Delay values equal to or greater than zero specify absolute time rates
from 0 to 127. Values less than zero specify Tempo-based mode. Refer to the
previous table for times and tempo-based rates.
Variation
LFO Variation sets the amount of random variation of the LFO each time
you press a key on the controller. This creates a chorus or ensemble effect
since each note played has a slightly different modulation rate. The higher
the value entered, the greater the note to note variation in the LFO.
The Variation value range is from 0 through 100.
__
__ Variation is disabled
when a Tempo-Based LFO is
selected.
LFO variation changes the rate of each note to create an “ensemble” effect.

PatchCords
PatchCords PatchCords tie everything together by connecting modulation sources to
destinations. Each PatchCord has its own Amount control which can be
positive or negative (negative amounts invert the signal). In addition, the
PatchCord amounts themselves can be controlled by any modulation
source. Halo provides 24 patches for each layer.
There are three permanently connected control routings: volume envelope
to amplifier, pitch wheel to pitch and key to pitch. All other connections
must be made using the PatchCords.
Each patch has an amount field which determines how much modulation
is applied to the destination. The modulation amount can be positive or
negative. Negative values invert the input. The amount value range is from
-100 to +100.

Modulator Polarity
You will notice that some of the modulation sources have symbols
following their names. For example, there are three Velocity modulation
sources, Vel +, Vel ±, and Vel <.
“+” Modulation: Uses only the positive half of the range, adding to the
current value. For example, if the filter frequency were set to 100 and you
patched Vel+ to the filter, the filter frequency would increase from 100 as
velocity was applied.
“±” Modulation: Uses both sides (full) range and both adding and
subtracting from the current value. For example, if the filter frequency
were set to 100 and you patched Vel ± to the filter, the filter frequency
would decrease from 100 with key velocities of 63 or less and increase from
100 with key velocities of 64 and above. Therefore with medium velocity,
the Filter frequency is approximately where you set it at 100.
An LFO ± works the same way; on the positive half of the cycle it increases
the initial amount and on the negative half of the cycle it decreases the
initial amount. With a ± modulation source, a value of 64 equals 0.
“<” Modulation: Uses only the negative half of the range, subtracting
from the current value. For example, if the Amplifier Volume were set to
+3 dB and you patched Vel < to AmpVol, the volume would be at +3 dB
only when maximum key velocity were applied. Lower key velocities would
scale back the volume. In general, < modulation is the proper choice when
modulating Volume.
++ modulation ADDS to the
initial value. (Normal)
< modulation SUBTRACTS
from the initial value
± centers around Zero.

Pitch Bend Range
Pitch Bend Range Specifies the Pitch Wheel range in semitones for the current layer. Pitch
Wheel is a standard synthesizer control which is transmitted as a MIDI
continuous controller message used (normally) to bend the pitch up and
down.
The PitchBend range is from 0 to +12 semitones or “Master.” A setting of
“0” turns the pitch wheel Off for the current layer. The Master setting uses
the Pitch Bend range defined in the Global menu.
Mix Output This feature allows you to program the Effect Send as a part of the preset.
Note that for this feature to work, the Mix Output setting in the Global
menu MUST be set to “Preset” on the selected MIDI channel. If you want to
define output routing by MIDI channel, set it up using the Mix Output page
in the Global menu. See “Mix Output” on page 86 for more information.
The Sends function as effect processor inputs (effect sends). The Output
Routing field shows the true routing of the Sends to the Main output.
To Control the Mix Output from the Preset:
1. Move the cursor until it is underneath the Layer field and change the
Layer using the data entry control.
2. Move the cursor until it is underneath the FX Send Routing field and
change the Send (1-4) using the data entry control.
3. Locate the MIX OUTPUT screen in the Global menu.
4. Set the MIDI channel you are using to “use preset”.

FXA Parameters
FXA Parameters The FXA parameters are Decay, High Frequency Damping, and the FxB to
FxA send. Decay sets the length of time it takes an effect to fade out. HF
Damping causes the high frequency energy to fade away more quickly
during the reverb decay. FxB to FxA controls the amount of the “B” effect
sent through effect “A”. This allows you to place the two effects in series
and create setups such as “distortion through reverb” among others. Please
refer to the Effects chapter for more information about the effects.
FXA Send Amounts These parameters set the effects amounts for each of the four stereo effects
busses.

FXB Parameters
FXB Parameters The FXB parameters are Feedback, LFO Rate and Delay. Feedback sends the
output of the effect back into the input. This creates multiple echoes on a
delay effect and intensifies a chorus or flange effect. LFO Rate allows you to
change the speed of the modulation oscillator for flange and chorus effects.
Delay sets the length of the delay line. This affects the time between
echoes, or the tone of flange effects.
FXB Send Amounts These parameters set the effects amounts for the four stereo effects busses.
Preset Patchcords Preset PatchCords give you real-time control of global parameters. The
effect processors are a powerful synthesis tool and this feature lets you
control and use them in exciting new ways. For example, you can dynami-
cally adjust the effects mix during a sequence or live performance.
There are many exciting performance possibilities using Preset PatchCords
to control Arpeggiator parameters and Effects Sends. The front panel knobs
15 & 16 are usually connected to Arp parameters in factory presets marked
“arp:” Be sure to try out these controls
There are 12 Preset PatchCords per preset with a source, a destination and
an amount control. The amount can be set from -100 to +100. The Preset
PatchCord controls are added to the FX Send Amounts set in the Global or
Preset Edit menus. In other words, multiple sources connected to destina-
tions are summed.

Initial Controller Amount
Initial Controller
Amount
This parameter sets the initial value of MIDI controllers A-P when the preset
is first selected. The front panel Control Knobs can be thought of as front
panel MIDI controllers because in the Halo, they are treated just as if they
originated from an external MIDI device. Refer to the following diagram.
There are 4 Initial Controller Amount screens (A-D, E-H, I-L, M-P).
External MIDI controller numbers are assigned to the Letters A-P in the
MIDI menu. The Initial Controller Amount value is sent to the PatchCord
destination when the Preset is first selected. If you move the Control Knob,
then that value replaces the initial value. If MIDI controller data is received
it will similarly replace the knob or initial setting.
The Initial controller amounts can be set from 000-127 or they can be
turned Off. If set to Off, the current controller value is used when the preset
is first selected. Setting the Initial Amount to “off” uses the values from the
previously selected preset.

Keyboard Tuning
Keyboard Tuning In addition to the standard equally divided octave tuning, Halo contains
twelve factory programmed tunings and 12 user-definable tunings. The
Keyboard Tuning parameter selects which tuning is used by the current
preset. The User Tuning tables are defined in the Global menu.
The factory Keyboard Tuning tables are described in the following table.
Refer to “User Key Tuning” on page 92 in the Global Menu chapter for
instructions on how to define your own Keyboard Tunings.
Tuning Tables Description
Equal Temperament Standard Western tuning
(12 equally spaced notes per octave)
Just C Just intonation. (Based on small interval ratios. Sweet
and pure, non-beating intervals.)
Vallotti Valotti & Young non-equal temperament. (Similar to 12
tone equal temperament. Each key has a different
character for a given scale.)
19-Tone 19 tone equal temperament. (19 notes per octave.
Difficult to play, but works well with a sequencer.)
Gamelan 5 tone Slendro and 7 tone Pelog. (Javanese. Pelog are
white keys, Slendro are black keys. Exotic tunings of
Gamelan flavor.
Just C2 Allows you to play the following chords in the key of C:
C, E, F, G, A, B, C#m, D#m, Em, F#m, G#m, Am, Bm
Just C-minor Allows you to play the following chords in the key of C:
C, E, F, G, A, B, Em, Am, Bm, C#m, D#m, G#m
Just C3 Allows you to play the following chords in the key of C:
C, D, F, Bb, C#m, Dm, Em, F#m, G#m, Am
Werkmeister III A “well” temperament developed in the 17th century.
Although you can play in all keys, each key sounds
slightly different.
Kirnberger Another well temperament developed by Johann
Philipp Kirnberger where no pitch is more than 12
cents off from equal temperament.
Scarlatti A variant of Meantone tuning which was used from the
15th to 18th centuries.
Repeating Octave Middle C octave is repeated up and down the keyboard.
Link with a preset in equal temperament to form
unusual inversion up and down the keyboard.
User 1-12 Define your own tuning tables (Global menu).

Preset Edit Menu
Keyboard Tuning
The Just C Tuning Tables
Well Tempered and Just were standard keyboard tunings up until the 20th-
century when the current “equal tempered” scale became prevalent. In an
equal tempered scale, the octave is equally divided into 12 parts. In Just or
Well Tempered scales, the 12 notes are separately tuned to produce pure
chords. However, in Just tunings you are limited to playing certain chords
and if you play the wrong chord it may sound very BAD!
Halo implements the
MIDI Tuning Dump protocol
which allows you to create
tuning tables on your personal
computer and download them
via MIDI. There are several
computer applications available
on the internet which let you
create and download tuning
tables via MIDI.
Halo allows you to modulate between keys by providing you 12 user tuning
tables. Tuning tables can be changed as you play using a program change
(create several presets with the same sound and different tuning tables), by
MIDI SysEx command (using a programmable MIDI footswitch or other
device), or using a continuous controller (link 2 presets and crossfade
between them using a controller).
The Just C2, Just C min, Just C3 Tuning Tables
These new tuning tables take the concept of just intonation a step beyond
previous products. Fully explaining the mysteries of just intonation is
beyond the scope of this manual, but the subject is covered exhaustively in
Hermann Helmholtz’s On the Sensations of Tone, available at most libraries
and bookstores.
The new tables are called Just C2, Just C3, and Just C Minor. Try playing in
the key of C/Cm using each table. You’ll quickly discover both the wonders
and the frustrations of just intonation! In Just C, for example, you’ll find
that the chords C, Em, F, G, and Am sound beautiful. If you hold one of
these chords, you’ll hear no “beating”. After playing for a few minutes,
switch back to Equal Temperament for a rude awakening!
At this point you might wonder why anyone would use Equal Temper-
ament to begin with. For the answer to that question, play a D, Dmi, or Bb
chord!.The intervallic ratios that make the C & G chords sound so pure
make the D chord sound horribly out of tune. That's why we had to include
Just C3. In this tuning, D, Dmi and Bb sound in tune, but the G chord will
sound wrong.
Each of the 4 tables allows you to play a different group of common chords
in just intonation. Sadly, there is no single 12 note tuning that will allow all
of the common chords to be in tune, and of course that's why they
invented the equal temperament tuning system that we use today.
Just C
Play these chords: C, E, F, G, A, Cm, C#m, Em, F#m, Gm, Am
Just C2
Play these chords: C, E, F, G, A, B, C#m, D#m, Em, G#m, Am, Bm
Just C2 minor

Preset Links
Preset Links You can link presets to other presets to create layering or keyboard splits.
The current preset can be linked with up to two other presets (Links 1 & 2).
Each linked preset can be assigned to a specific range in order to create
keyboard splits or can be assigned a velocity range to switch links according
to key velocity. In addition, you can specify Volume, Pan, Transpose and
Delay settings for each Link. The modulation parameters specified in each
preset remain in effect for each preset in the link.
Links provide an easy way to create new sounds by combining the existing
presets. Or, you can create your own custom stacked presets with up to 12
layers! We’re talking LARGE sounds here. Of course Links can also be used
when you just want to stack up two sounds.
As an example, let’s stack two presets to create a big sound. Start with a
preset you like, then go into the Links screen and start scrolling through
the preset list while you play to hear both presets together. When you find
a winner, simply Save the preset and you’re finished!
•You can “Split” the keyboard up to 12 ways by using combinations of the
Layers and Links.
•By adjusting the Velocity for the link, you can bring in the link by
playing hard.
•Transposing the Link can radically change the sound.
•The delay parameter lets you create surprise effects, echoes or cascades of
sound as you continue to hold the keys.

Preset Tempo Offset
Preset Tempo Offset This function allows you to double or halve the Master Tempo as it applies
to this preset. When playing or sequencing several presets in Multi mode,
the Master Tempo may be too fast or slow for one preset. Using this feature,
you can adjust the tempo for the misbehaving preset. The Tempo Offset can
use the current tempo or be set to half or twice the current tempo.
Audition Riff
Selection
A Riff is a short pre-recorded musical phrase which can be anything from a
single note to a full 16-track sequence. This function allows you to assign a
Riff to a Preset. The Preset Riff will be used when the front panel Audition
button is pressed.

OO Listening to the Riffs is a
quick way to learn the sounds in
Halo. If a preset has hidden
tricks or controllers, these will be
shown off in the Riff.
The Riffs themselves cannot be modified.
Play Solo Layers When constructing multilayer sounds it is often useful to turn off one or
more of the layers so you can hear what you’re doing! This feature allows
you to temporarily solo individual layers or listen to them in any combi-
nation. This screen differs from the other Preset Edit screens in that it is
NOT saved with the preset. The values reset each time you exit the Preset
Edit menu.
Solo is activated by setting any layer to On (On = the layer is being Soloed).
Any layers set to On will play and any layers set to Off will be muted. If all
layers are set to Off, then Solo mode ends and all layers play normally.

Overview
Halo has two stereo effects processors. When playing presets one at a time,
the two processors can be programmed as part of the preset. When the
MIDI Mode is set to “multi,” the Halo uses a global effects assignment
(Master Effects). The diagram below shows how the effects are integrated
into the signal path using a parallel effects send/return model, similar to a
mixing console.
The Effects Sends On a mixing console you can control the amount of signal each channel
Sends to the effect bus. This allows each channel to be placed in a slightly
different “sonic space” which creates an airy, open sound.
Halo uses this basic concept, but works in a slightly different manner. There
are four effects busses: Send1-Send4. Each preset or each MIDI channel (you
determine which), can be directed to one of the four busses. Each effect
processor has four Send Amounts which allow you to set the wet/dry mix
on each of the four busses going into the effect. A setting of 0% is
completely dry (no effect). A setting of 50% contains an equal mix of
affected and normal (dry) signal.

Effects Overview
Send 2 is also used to route sounds to the Sub 1 outputs on the back panel.
When a plug is inserted into the associated Submix jack on the back panel,
the Dry portion of the Send is disconnected from the effects processor and
the Dry signal is routed directly to the output jack. The Arrow (->) in the
display points to the actual output routing. The Dry Send is disconnected
from the Effects Processors even if only one plug is inserted into a Submix pair.
The Effects Send is programmed for each layer in the Preset Edit menu.
These routings can be overruled in the Global menu Mix Output screen by
changing the submix setting from “preset”, which uses the preset routing,
to Send1-Send4. In the diagram below, MIDI channel 1 is programmed to
obey the preset routing, which in this case is Send 1.
Individual layers or entire MIDI channels can be routed to any of the four busses.
The four Effect Sends allow you to get the most out of the two effect
processors. For example, with Effect B set to an echo algorithm, you could
route one MIDI channel to Send 3 and set the effect amount to 80%.
Another MIDI channel could be routed to Send 4 with an effect amount of
only 5%.
The Mix Output function is also useful when sequencing since it lets you
route specific MIDI channels to specific Sub outputs (on the back panel)
where there they can be processed with EQ or other outboard effects.

Effect Types
Decay
The Decay parameter is used when setting “A” type effects. Decay sets the
length of time it takes an effect to fade out. When setting up reverb effects,
Decay controls the room size and the reflectivity of the room. For larger
room sizes and greater reflectivity, set the Decay value higher. When setting
up delay effects, the Decay parameter controls how many echoes are
produced or how long the echoes last. The greater the value, the more
echoes and longer lengths of time.
The Decay value range is from 0 through 90.
High Frequency Damping
The HF Damping parameter is used when setting “A” type effects. High
Frequency energy tends to fade away first as a sound is dissipated in a room.
the HF Damping parameter adjusts the amount of damping applied to the
signal’s high frequency elements which, in turn, changes the characteristics
of the room. Rooms with smooth, hard surfaces are more reflective and
have less high frequency damping. Rooms filled with sound absorbing
materials, such as curtains or people, have more high frequency damping.
The value range for High Frequency Damping is from 0 through 127.
Feedback
The Feedback parameter is used when setting “B” type effects. The Chorus
and Flange effects have a controllable feedback loop after the delay
element. Feeding back a small amount of the signal intensifies the effect by
creating multiple cancellations or images. Higher feedback values increase
the amount of the Feedback loop.
The Feedback value range is from 0 to 127.
LFO Rate
The LFO Rate parameter is used when setting “B” type effects. Both Chorus
and Flange effects use a Low Frequency Oscillator (LFO) to animate the
effect. LFO applied to a chorus effect creates the slight changes necessary
for a realistic choral effect. Applied to a flanger effect, the LFO moves the
comb filter notches and adds animation to the sound.
The LFO Rate value range is from 0 to 127.
Delay
Flanging, chorus and echoes are all based on a delay line where the signal is
delayed by some time period and then mixed back with the unaltered
signal. This parameter specifies the how much time passes before you hear
the delayed signal. On some effects, this value cannot be changed. In this
case, the field contains a dash.
The Delay value range is from 0ms to 635ms.

In Multi mode, the two effects processors can be controlled from the Master
Effects settings or they can follow the effects settings of the preset on a
special MIDI channel. The effect settings on this special channel will be
applied to all the other MIDI channels. This allows the effects to be
changed during a sequence simply by changing the preset on a specified
MIDI channel.
To Program the Effects by Channel Number in Multi Mode:
1. Press the MIDI menu button. The LED illuminates and the MIDI menu

the actual channel number from 1 through 16) using the data entry
control.
5. Press Enter to save the settings and return to the main screen.
Effect B Into Effect A The output of effects processor B can be routed into effects processor A.
This connects the effects in series instead of their normal parallel configu-
ration. Two effects connected in series sound very different than the same
two effects in parallel. For example, a chorus patched through reverb can
turn a bland string section into a lush wall of sound. The B –>A amount can
also be controlled for even more flexibility.
To Send the Output of Effect B through Effect A:
In this example, 100% of Effect B will be sent into Effect A.

Reverb Reverberation is a simulation of a natural space such as a room or hall. The
reverb algorithms in Halo simulate various halls, rooms and reverberation
plates. In addition, there are several other reverb effects such as Gated
Reverbs, Multi Tap (early reflections), Delay and Panning effects. There are
two adjustable parameters on the reverb effects - Decay Time and High
Frequency Damping.
Decay time defines the time it takes for the reflected sound from the room
to decay or die away. The diagram below shows a generalized reverberation
envelope.
After an initial pre-delay period, the echoes from the closest walls or ceiling
are heard. These first echoes, or the early reflection cluster, vary greatly
depending on the type of room. Roughly 20 milliseconds after the early
reflection cluster, the actual reverberation begins and decays according to
the time set by the Decay Time parameter.
High frequency energy tends to fade away first as a sound is dissipated in a
room. The High Frequency Damping parameter allows you adjust the
amount of high frequency damping and thus change the characteristics of
the room. Rooms with smooth, hard surfaces are more reflective and have
less high frequency damping. Rooms filled with sound absorbing materials
such as curtains or people have more high frequency damping.

General Descriptions of the Reverb Types
Room: Programs simulate small rooms with high frequency absorption

Plates: Simulates plate type reverbs with their tight, dense, early

Hall: Presets recreate the open, spacious ambience of large concert halls.
Gated Reverbs: Add ambience only while the original signal is still
sounding. As soon as the signal falls below a threshold, reverb is cut off.
Delay: Programs can be used to create echo and doubling effects.
Multi Tap: Programs consist of the reflection cluster only without the
reverb decay.
Halo Operation Manual 185
Effects
General Effect Descriptions
Chorus The function of a chorus device is to thicken the sound or to make one
voice sound like many. This effect is usually created by mixing one or more
delayed versions of the signal with the original. The delay times used are
too short to be perceived as an echo, but long enough so that comb filtering
does not occur. In addition, the delay time is varied via a low frequency
oscillator to simulate the random differences which occur when multiple
instruments are playing together. A slight amount of feedback improves the
effect by creating multiple images of the sound as it recirculates again and
again.
All the choruses are true stereo using two separate delay lines controlled by
a single set of controls. The delay times are slightly different for each
channel and the LFO phase is inverted on one channel to help contribute
to the overall chorus effect. The LFO Rate and Depth settings are critical to
achieving a realistic effect, with faster LFO rates generally requiring less LFO
amount and vice-versa.
Doubling When a copy of a sound delayed by about 26 milliseconds is added back to
the original, two audio images are perceived by your brain. When the
delayed image is slightly varied or modulated, the illusion of two voices is
created.
Slapback Slapback is a single short echo in the range of 50-60 milliseconds. A sound
delayed by this length of time is perceived as a discrete and separate image
which is useful for a thickening effect or as a pre-delay for reverb simulating
a hard, reflective surface such a gymnasium wall.
Stereo Flanger A flanger consists of a short audio delay line whose output is mixed
together with the original signal. Mixing the delayed and original signals
results in multiple frequency cancellations called a comb filter. Since the
flanger is a type of filter, it works best with harmonically rich sounds.
This is the frequency response of a Comb Filter.
Flanging was originally created using two tape recorders playing identical
recordings. By exactly synchronizing the two decks and then slowing the
speed of one by grasping the tape reel flanges, the flanging effect was born.
186 ENSONIQ
Effects
General Effect Descriptions
The Halo flanger is a stereo device consisting of two separate delay lines
controlled by a single set of controls. A Low Frequency Oscillator (LFO)
varies this initial delay setting, changing the frequency of the notches and
adding animation to the sound. LFO Rate controls the rate of change and
LFO Depth controls how much the LFO changes the delay.
The Feedback control sends some of the delayed signal through the delay
line again. When feedback is used the comb filter notches are deepened.
Delay Delay is an effect which can be used for doubling, reverb pre-delay, or
echoes.
Delay Time is variable from 0-635 mS and controls the time between
echoes. Feedback and determines how long the echoes continue sounding.
“Infinite” delay effects are also possible without the risk of runaway.
Stereo Delay Similar to delay except that the delay line outputs a stereo signal from the
mono input. The two output signals are a few milliseconds apart to create a
stereo image. The delay times are variable from 0-635 mS.
Panning Delay A panning delay is similar to the normal delay lines except that the echoes
bounce back and forth between the two stereo speakers.
Dual Tap These are delay lines where the signal is “tapped off” at two unevenly
spaced locations. When feedback is used, multiple complex echoes are
produced. The fraction in some of the algorithm names (i.e. 1/3, 1/4) refers
to the time ratio between the taps.
Vibrato Basically, this a delay line modulated by an LFO, but with none of the
original signal added in. The LFO modulation creates a Doppler shift and a
resultant cyclical pitch shift. The vibrato created in this manner sounds
very different than vibrato created by frequency modulating the sample.
Distortion Distortion uses a technique called “soft-clipping” to create additional
harmonics in the signal. As the level increases, the top of the waveform
becomes somewhat squared. As the level increases further, it transforms
into a true square wave.
Soft clipping gradually squares the edges of the waveform as the amplitude is increased.

There is so much you can do with the Halo it would be impossible to
describe it all. This chapter is will give you a few ideas for programming
your own custom sounds and contains step-by-step instructions to help
you get started. In order to get the most from this chapter, we recommend
you actually try each example.
Editing Presets One of the easiest ways to make a new preset is to edit an existing preset.
This is also an excellent way of becoming familiar with Halo. If you don’t
like what you hear, simply select a new preset, then Halo reverts to the
original sound. Changes are not permanent until you Save them (see
“Saving a Preset” on page 187).
Let’s experiment and modify a few parameters of an existing preset. We’ll
start with functions that have an obvious effect on the sound: Instrument
Select, Tuning, and Chorus.
Changing the
Instrument
Changing the instrument is the easiest and most dramatic way to modify
an existing preset.
To Change the Instrument for the Current Layer:
1. Choose any cool preset, then press the Preset Edit button.
2. Press the #1 Jump button twice to jump directly to the Instrument
page. See “Preset Menu Jump Keys” on page 36.
OO
OO The Preset Edit Jump
Buttons are located in the
“Command Functions” section
of the front panel.
3. Move the cursor down to the bottom line (using a Cursor button).
4. Use the Channel button to turn select the various layers. Use the data
entry control to turn OFF all layers except L1. This allows you to hear
the different instruments by themselves.
5. Play the keyboard as you scroll through the various instruments.

Preset Programming
Editing Presets
To Change the Instrument for any Layer in the Preset:
6. Use the Channel Select buttons to select another layer.
7. Find another instrument that sounds good when combined with the
previous instrument selected.
8. Repeat steps 6 and 7 if you want to add additional layers (although two
layers will be enough for these experiments).
Now let’s play with the tuning.
Changing the Tuning
of an Instrument
Tuning the selected layer of the preset changes the pitch of the key on the
controller. If the numbers are “00,” it means that the instruments are tuned
to concert pitch (A=440 Hz). The Coarse tuning value represents whole
semitone intervals. The Fine tuning value shifts the pitch in 1/64 semitones
(or 1.56 cents).
To Tune the Instrument of the Current Layer:
1. Press the #3 Jump button twice to jump directly to Tuning page.
2. Move the cursor to the Coarse field (using the cursor button).
3. Set the value to +12 to shift the pitch up a whole octave. To shift the
pitch in smaller units than a semitone, use the Fine field.
Try tuning one of the instruments to a perfect fifth above the other by
setting the Coarse value to +7.
Tuning an instrument far out of its normal range completely changes the
character of the sound. For example, if you tune a bass guitar up 2 octaves,
it's going to sound rather petite. On the other hand, if you tune it down 2
octaves, you can probably rattle plaster off the walls! Experiment with
radical pitch shifting. You'll be surprised at the results.

Chorus This is an easy one. Chorus works by doubling the instruments and
detuning them slightly. The larger the chorus value, the more detuning
occurs. The Width parameter controls the stereo spread. A Width value of
0% reduces the chorus to mono, a value of 100% provides the most stereo
separation. Chorus is useful when you want to “fatten up” a part quickly
and easily.
To Chorus a Layer:
__
__ WARNING: Since it
works by doubling the
instruments, Chorusing halves
the number of notes you can
play on Halo.
1. Press the #5 Jump button to jump directly to the Chorus page.
2. Use the cursor buttons to advance the cursor to the Chorus field (the
first field in the bottom line of the display). Use the data entry control
to turn on chorus.
3. Select a Width value based on the amount of detuning you want.
Smaller numbers mean less detuning, larger ones more.
You can select various amounts of chorusing for each of the instruments,
just play around with the Chorus and Width parameter until you like what
you hear.
Volume Envelope Every sound you hear, whether it’s a piano note, a drum, or a bell, has a
characteristic volume curve or envelope. This Volume Envelope shapes the
volume of the sound which grows louder or softer in various ways during
the course of the sound. The volume envelope of a sound is one of the clues
our brain uses to determine what type of sound is being produced.
An envelope shapes the sound or volume of the sound over time. The
envelope generators in Halo all have six stages to the contour: Attack 1,
Attack 2, Decay 1, Decay 2, Release 1 and Release 2. When you press a key
on the keyboard, the envelope goes through each of the first four stages,
advancing to the next stage when the defined Level for each is reached. As
long as you continue to hold the key down, the envelope continues
through the first four stages holding at the end of the Decay 2 level until
the key is released. When you release the key, the envelope jumps to the
Release stages (no matter where the envelope is when you release the key)
ending at the Release 2 level.

Every instrument in Halo has it's own predetermined volume envelope
which is used when the Volume Envelope parameter is set to “factory.” By
setting the Volume Envelope to “time-based” or “tempo-based,” we can
reshape the instrument's natural volume envelope any way we want. By
reshaping the volume envelope of a instrument, you can dramatically
change the way the sound is perceived. For example, you can make
“bowed” pianos or backward gongs. The diagrams to the left show the
characteristic volume envelopes of a few common sounds.
In preparation for this experiment choose almost any of the standard organ
presets which sustain as long as the key is held down. Go to the Instrument
page and set it to “None” on all layers except Layer 1. Now you’re ready to
play with the Volume Envelope.
Adjusting the Volume Envelope (the easy way):
Many sounds don’t require a complex six-segment envelope. Over the
years, a simpler Attack-Decay-Sustain-Release envelope, or ADSR, have
become standard. The front panel controller knobs on Halo have been
preprogrammed to adjust these four volume envelope parameters. A
diagram of this standard ADSR envelope is shown below.
1. Front panel knobs E-H are routed to the volume envelope parameters.
This is the easiest way to change the volume envelope settings.
2. Press the front panel Controller button E-H to select: Amp Attack, Amp
Decay, Amp Sustain, Amp Release.

3. Increase the Amp Attack knob and play a note. The attack controls the
time it takes for the sound to reach the Attack level when a key is
pressed and held.
4. Increase the Amp Release knob. Note the effect as you release the key.
The Release stages controls the time it takes for the sound to die away
when a note is released.
5. Try out the Sustain & Release knobs. The Sustain knob control the
volume LEVEL after the Decay phase has finished and while the key
continues to be held. As soon as you release the key, the Release phase
begins.
To Create a Complex Volume Envelope:
1. Go to the Volume Envelope mode screen, by pressing the “Amp” jump
button twice, and set the Volume Envelope mode to “time-based.”
2. Now move on to the next screen to set the Volume Envelope
parameters.
Front panel knobs 5-8
are routed to the volume
envelope parameters and thus
affect the settings. You may
want to disconnect the
PatchCords to gain total control
of the envelope parameters.
(Alternately, you can create a
completely blank preset and start
from there.)
3. Increase the Attack 1 time value and play a note. The attack controls
the time it takes for the sound to reach the Attack level when a key is
pressed and held.
4. Move the cursor to the first field in the bottom line and use the cursor
buttons to advance to the Release pages.
5. Increase the Release 1 and 2 times. Note the effect as you release the key
on the controller. The Release stages controls the time it takes for the
sound to die away when a note is released.
To Setup the Volume Envelope as an ADSR:
The classic synthesizer ADSR (Attack-Decay-Sustain-Release) envelope is
easy to create using the Halo six segment envelope generators. The trick is
to only use segments: Attack1, Decay2, and Release1.
1. Set Atk1, Atk2 & Dcy1 levels to 100.
2. Set Rls1 & Rls2 levels to 0.

3. Set Atk2, Dcy1 and Rls2 rates to 0.
4. Program the Atk1, Dcy2 and Rls1 segments as you wish. Decay 2 level is
your Sustain level.
Working with Filters The filters make it possible to remove certain components of the sound. A
low pass filter removes the high frequency components or put another way,
it “lets the low frequencies pass.” A high-pass filter removes the low
frequency components from the sound letting only the high frequencies
pass. See “Halo Filter Types” on page 148 for a complete list of Halo’s filters
and their descriptions.
In preparation for the next tutorial, set up the Halo with a single
instrument layer on Layer 1.
1. Go to the Instrument screen (Preset Edit menu) and select Instrument
#140 - wav:Sawtooth 1. This is a harmonically rich sound. Since filters
work by removing or accentuating certain frequencies, we want to
make sure that we have a lot of frequencies to start with.
1. Advance to the Filter Type screen using the data entry control. Select
the Classic 4th order filter.
Front panel knobs A & B
are routed to the filter
parameters and will affect the
initial settings made here.
1. The Filter Frequency and Q (resonance) are preprogrammed to the front
panel controller knobs A & B. This is the easiest way to change the
volume envelope settings.
2. Press the front panel Controller button A-D to select controls A-D
The Frequency parameter determines the filter cutoff frequency or the
frequency the filter uses as the highest frequency allowed to pass. If you
play the keyboard now, you should hear the raw sound. Slowly decrease
the filter cutoff frequency value as you play the keyboard. The sound

gets more and more dull as you remove more and more high
frequencies from the sound. At some point, the sound completely
disappears. (You have filtered out everything.) The chart on the
following page illustrates what you just did.
3. Turn the filter back up to full, then adjust the Q.
4. Set the Q about halfway up, then adjust the Cutoff as you play the
keyboard. As you change the Cutoff, notice that the sound now has a
sharp, nasal quality. A high Q boosts or amplifies the frequencies at the
cutoff frequency (Fc).
Adding the Filter Envelope
Now let's modulate the Filter Frequency with the Filter Envelope. The Filter
Envelope is a device that can automatically change the filter frequency
during the course of the note. Before we define the Filter Envelope, we need
to patch the Filter Envelope to the Filter Frequency.
To Setup the Filter Envelope:
1. Go to the PatchCord screen by pressing the Cords Jump Key.
2. Move the cursor to PatchCord #3. This patchcord is preprogrammed to
connect the Filter Envelope to Filter Cutoff Frequency.
3. Move the cursor to the last field in the lower line. This is the Amount
field. The Amount field determines the amount of modulation applied.
Set this value to +100.

9. Change the attack rate and note the change in the sound.
10. Set the envelope parameters as shown in the following table.
With the above setup, the filter sweeps up, then Decays back down to
the Decay 2 Level until you release the key. Then it sweeps down at the
Release rates. Play with the envelope parameters for awhile to get a feel
for their function. (If you're having trouble understanding the Envelope
Generators, please refer to the Programming Basics section in this
manual.)
Changing Filter Types
Go back to the Filter Type screen shown below and move the cursor down
the lower line of the display. Change the filter type while playing the
keyboard. There are 50 different filter types.
These filters are extremely powerful and have been carefully crafted to offer
maximum flexibility and musical control. You may want to change the
Envelope (PatchCord) Amount, Q and/or the Filter Frequency to get the
right sound for each filter and instrument. These three controls, coupled
with the Filter Envelope, are perhaps the most important controls on any
synthesizer. Take the time to learn how they interact with each other and
you will be able to create sounds beyond imagination.

Envelope Repeat
The Envelope Generator can also be made to repeat. When the envelope
repeat function is On, the Attack (1&2) and Decay (1&2) stages will
continue to repeat as long as the key is held.
To Make the Filter Envelope Repeat:
1. Go to the Filter Envelope Mode screen shown below.
2. Move the cursor to the Mode field.
3. Turn the data entry control clockwise. The Mode field will change to
Repeat as shown below.
4. Move the cursor to the on/off field and turn Envelope Repeat On.
5. Play a key on the keyboard. You should now hear the envelope
repeating.
6. Go back to the envelope parameter page and adjust the Attack 1&2,
and Decay 1&2 parameters. The repeating envelope cycles through
these four stages as long as the key is held.
Practice Modulating •Try modulating the pitch with the Filter Envelope generator.
•Use Velocity to modulate the Filter Envelope PatchCord or the Filter
Frequency. This brightens the sound as you play harder.
•Program the LFO to modulate Filter Frequency and Volume (Patch-
Cord screen).
•Modulate the LFO with the other LFO, with Velocity, and with the
Pitch Wheel.
•Examine the Factory presets to learn how they’re constructed. There
are lots of cool synthesis tricks you can use in your own presets.
•We’ve programmed the front panel knobs our way, but since they’re
completely programmable there’s no reason why you can’t create
your own custom controls.
•Think of ten exotic modulation routings, then try them out.
Experimentation is the key to learning how to control Halo.

Troubleshooting A common source of confusion when working with the filter envelope is
that the Attack or Release parameters might not seem to be working
correctly. If you are not getting the expected result, try to analyze the
situation. There will be many times when you will have to stop for a
minute and think, “What am I trying to do and why isn't it working?”
When this happens (and it will), don't panic. Troubleshooting is a normal
part of the synthesis process. Simply examine the various parameters and
try to be as analytical as possible as you solve the problem. The solution is
usually simple. (“The filter is already wide open and can't open any more.”
or “Another PatchCord is connecting something to the parameter and
affecting it.”) Learning to play any instrument takes a little patience and
practice.
Referring to the diagram below which shows the Halo signal flow, notice
that the DCA comes after the Filter. The DCA controls the final volume of
the sound, so if the filter's release is longer than the release for the DCA,
you won't hear it, because the DCA has already shut off the sound.
You’re getting the general idea by now. Remember not to select a new
preset before saving the current one or all your changes will be lost (the
preset reverts to the last saved version). If you want to save your creation,
select the Save/Copy menu and select a destination preset location for your
masterpiece, then press Enter.
Because you can save your work, it’s worth spending time to get the sound
just right. When designing sounds you become an instrument builder as
well as a musician. With Halo you can design the custom radical instru-
ments you’ve always wanted!

Installing Sound SIMMs
Installing
Sound SIMMs
Halo can be easily expanded to contain up to 128 MB of sound data
(4 SIMMs).
Remove the ROM Hatch Cover:
1. The sound SIMM sockets in Halo are located beneath a small hatch on
the bottom panel. Unplug power from the unit and carefully turn it
keyboard-side down on a soft, padded surface.
2. The ROM hatch is a 125cm x 140cm rectangle secured by four screws.
(You can’t miss it.) Remove the four phillips head screws securing this
hatch and place them and the hatch cover where they won’t get lost.
To Remove ROM SIMMs (if necessary):
1. Orient the unit so that the rear panel is facing you. Ground yourself by
touching a grounded object. (Such as the chassis of another piece of
equipment connected to the wall socket with a three-prong power plug.)
2. On each end of the SIMM socket there is a silver or plastic tab. Use a
screwdriver or a ball point pen to squeeze the tabs toward the outside of
the socket while gently nudging the SIMM toward the right side of the
unit. The old SIMM should “hinge” to the right and can now be
removed.

2. Tilt the SIMM up
so that both tabs

Halo Operation Manual 233
Appendix
Installing Sound SIMMs
Install a New ROM SIMM
1. Ground yourself by touching a grounded object, then remove the
memory SIMM modules from the static protected packaging.
2. Notice that one end of the SIMM connector is notched. This notch
Install the SIMM closest to the LEFT side first. (When the rear of the unit
is closest to you.)
3. Gently set the SIMM deep into the SIMM socket at a 45º angle with the
notch toward the keyboard. Without forcing the insertion, let the board
rest in the socket as deep as it will go. It should rest naturally in place at
this 45° angle. See the following diagrams.
4. While applying a slight downward pressure on the top of the SIMM to
keep it from popping out of the socket, tilt the SIMM board into a
vertical position. You should hear an audible click. Make sure both sides
of the silver tabs have latched.
Reassemble the Unit
5. Replace the hatch cover and the four screws. The screws are all
identical.
Test It
The installation is almost finished.
1. Turn the unit right-side up and plug in the power cord.
2. Turn on power.
3. Place the cursor under the ROM field of the Main screen and turn the
data entry control to verify that the new sound ROM has been recog-
nized.
4. Play the presets on the new ROM banks and verify that they sound OK.
Problems?
1. Disconnect power immediately.
2. Open the unit, and try re-seating the ROM SIMMs. Take care that the
RAM SIMMs are properly installed in the sockets. If you’re still having
problems, return the unit to its original configuration and call EMU /
ENSONIQ Customer Service at (831) 438-1921. Telephone support
hours are 8:00-5:00 PST, Monday through Friday.

NOTES: * Halo can transmit and receive ANY continuous controller number
from 1 to 95. Because of Halo’s powerful synth engine, many of
the standard MIDI controllers can be user programmed to provide
the desired function. A “Yes” response in this chart means that a
controller is programmed by default in Halo.
Controller 79 is hard-coded to the Mix Output parameter.
0=Use Preset, 1=Send 1, 2=Send 2, 3=Send 3, 4=Send 4
Controller 80 is hard-coded to the Arp Status parameter.
0=Off, 1=On, 2=P (preset), 3=M (master)
Value of 0 = reset all except vol & pan; value of 127 = reset all
Other: Pan: -64 = hard left, +63 = hard right

There is only one edit buffer which is used by the current preset (the preset
shown in the display). You can edit only one preset at a time via SysEx
commands, although these presets can be edited independently of the
current preset edited using the Front Panel. Remote Preset selection is
independent of the edit buffer. Changing the current preset erases the edit
buffer.
