HX3 Mainboard
(Firmware version 5.4)
HX3.5 is a tonewheel organ emulation with all B3
features on a single board, creating the legendary
unmatched HX3 sound. Controlled via MIDI, it
offers selectable CC-sets for various keyboards.
Alternatively, it may be controlled directly by Fatar
keybeds as well as drawbars, switches and
buttons. HX3 provides unlimited polyphony,
presets, parameters tweakable by simple menus.
In addition, General MIDI sounds like piano and
strings are available.
As an option (extended licence required), the new HX3 RealOrgan engine is capable of emulating
all electromagnetic organs including the famous H100, combo organs, concert organs of the 70s
and 80s like Böhm Orchester and Wersi Helios. This implies up to 15 harmonics, up to 12
drawbars per manual with individual mixtures, including phasing rotor (WersiVoice), mechanical
and electronic keying available simultaneously. ADSR envelope available on all drawbars, also
H100 percussion and "Harp Sustain". Various tone generator waveforms selectable, for "cheesy"
combo organs as well as fully fledged concert organs.

Jack Connections
The HX3.5 mainboard features two 1/4" mono audio output jacks, two standard MIDI jacks, one
DC input jack, one USB connector and two accessory jacks for external usage.
SWELL PEDAL ¼” stereo jack. Expression pedal input is compatible with Yamaha FC-7
and similar expression pedals (direct connection preferred for speed/accuracy, but may
also be remote controlled by MIDI control change, controller 11). Plug connection: Sleeve =
ground / potentiometer start, ring = potentiometer tap, tip = potentiometer end.
FOOT SWITCH ¼” stereo jack. Single or double footswitch controls simulated rotary
speed: SLOW/FAST on plug tip, RUN/STOP on plug ring. Please use latching foot
switches; momentary (button type) switches are not supported. If single footswitch used,
Rotary is always on RUN (no plug ring, input grounded by plug sleeve).
MIDI IN/OUT factory default secondary MIDI input for additional lower manual, bass pedal
or MIDI controller. Internally jumpered to supply +5V/200ma to our Drawbar Controller
(phantom voltage). May be changed to act as MIDI OUT by internal jumper swap. See our
wiki page for details.
MIDI IN primary input from MIDI keyboard.
DC IN: Use stabilized DC wall wart 9 to 12V with at least 500mA current output, inner/outer
plug diameter 2.1/5.5 mm on DC input jack. Polarity: positive voltage on inner tip.
USB: USB B connector for MIDI over USB and GM Soundbank updates (optional).
AUDIO1/AUDIO2: Main audio stereo output. Output level is approx. 300 mV at full swell.
For full control of parameter settings, we recommend the use of our MenuPanel. Installing the
menu panel and other peripherals is described in the HX3.5 Installation Manual, which you
download from http://wiki.keyboardpartner.de/index.php?title=HX3.5_Installation_Manual. The
menu system for a standard organ configuration, using drawbars, our Panel16 switch button
board, and keybeds connected through our key scanning boards is described below.
Please note: Factory default programming is the MIDI expander firmware. By means of the HX3.5
Editor you may set up the HX3.5 mainboard conveniently for your organ configuration. See the
HX3.5 Editor User Manual for details.
Volume Control
Output level of all output channels is controlled by Master volume setting in menu or MIDI CC #7
“Volume”, whichever occurs last.
Organ's swell pedal position is controlled by an expression pedal or MIDI CC #11 “Expression”,
whichever occurs last. HX3 resembles a loudness curve similar to the swell pedal of a classic
tonewheel organ, so expression volume will not reach zero. We recommend connecting an
expression pedal Yamaha FC-7 or similar (1/4" jack, 10k to 47k total resistance) directly to the
HX3 module. By using an expression pedal rather than MIDI sweller control will be faster and
more precise.
MIDI CC #11 and #7 may be changed by menu to any other valid MIDI CC number.
Panel Buttons
Up to 64 buttons may be connected to the board; a standard organ uses at least 16. In standard
configuration, one Panel16 is needed. See
http://wiki.keyboardpartner.de/index.php?title=HX3.5_Installation_Manual#Panel16 for details.
Menu Panel
On power on, the presets/drawbar menu is present. Pressing the rotary knob twice briefly will let
you return to the presets/drawbar menu from any other menu position. The menu entry count
depends on licence, organ model, and menu configuration.
Turn the rotary know to select overall Overall Presets 0 … 15. Overall presets consist of voice
numbers for upper manual, lower manual, and pedal, tab switch settings (percussion, vibrato etc.),
volume and 122 tube amp gain as well as all other effects, except rotary run/fast/slow. LEDs are
indicating current percussion and vibrato setting.
Press the up/down buttons to step through the menu (autorepeat if you keep the button pressed).
Turn the rotary knob to change a parameter value. A white arrow indicates the selected entry
that may be altered.
Alternatively you may use the rotary knob to scroll through the menu. Press the rotary knob once
briefly. Up/down arrows are white (active) and parameter arrow is outlined (inactive) in this mode.
Press rotary knob again briefly to change an entry.
Scroll one step upwards in the menu to the Master Volume setting. Master Volume sets final
volume of all outputs. For best noise performance, higher values are desirable.
Scroll another step upwards to the TubeAmp Gain setting. TubeAmp Gain sets volume of the
internal rotary tube amp simulation from 0 to full (overdriven tube amp). The simulated Amp will
get into decent saturation on increased swell amount and higher gain values as seen on ‘real’ tube
amps. Amount of distortion is controlled by swell pedal.
A star appears on the display, if a parameter value has been changed and now differs from the
stored preset. To store values as preset, keep the encoder knob pressed until the prompt “Saved
to Preset #XX” appears on the display. (“XX” representing the current preset number).
Parameter values tagged by the letter C are part of a single preset. Values tagged by D apply to
all presets and are stored as defaults. Values tagged by U, L, or P are part of the current voice.
40 voices 0 … 39 are available for each manual and pedal. Voices 0 … 15 contain the organ
drawbar settings. Voices 16 … 39 select a General MIDI (GM) instrument. GM voices may be
predefined by use of the HX3.5 Editor application.
The current voice settings are stored along with the overall preset. Drawbar settings are being
stored as voices carrying the same number, while GM instruments will retain their selected
numbers.
Independent of the current overall preset you may select any stored voice by choosing its number
in the voice menu, and then modify the voice as you like and play it live or store it again along with
an overall preset.

The HX3.5 menu is arranged as a loop. So you may reach any menu entry by either pressing the
up or the down button. But it is a good idea to memorize the menu positions, enabling you to reach
frequently used entries located around the preset/drawbar entry more quickly.
Menu Upper/Lower/Pedal
Starting from the preset/drawbar menu, scroll one step downwards to the voice settings for upper
manual, lower manual, and pedal. The white arrow is pointing to the selected manual.
DrbXXXXXXXXXXXX – the voice menu indicates upper/lower or pedal drawbar settings as
numbers 0 … 8 (here represented as "X") for 12 drawbars (9 harmonics plus 3 mixtures).
For the GM voices the instrument’s name is being displayed instead.
Turn the rotary knob to alter a voice setting
Generator models
Scroll upwards, starting from the preset/drawbar menu, to the organ model settings. Several menu
entries are available with Extended Licence only (marked by italic letters in the schematic). Also
you have a choice of more organ models with the Extended Licence. The number of menu entries
depends on the selected organ model as well (default: B3). Menu entries available in H100 mode
are marked by H. Menu entries available in Electronic Gating (EG) or Versatile modes are marked
by E.
Navigate to the Generator menu entry to select the sound generation type:
B3 default (91 tones sound generator)
B3 old (as above, but more leakage, stronger key click)
M3/M100 (no foldback for higher tones)
H100 (96 tones sound generator)
LSI Sine (phase stable frequency dividing generator like Wersi/Böhm)
LSI Square (as above, more harmonics)
Conn SNG (free running single sine tone generator, 91 tones, not phase stable)
CheesyCombo (84 tones generator, phase stable frequency divider, „cheesy sound“, rich
harmonics
Organ models
The HX3.5 default setting (B3 mode) implies mechanical key contacts, 2 2/3’ or 4’ percussion, and
9 drawbars per manual.
Select H100 mode for the H100 organ model of the H100 including 3 additional mixtures. This
activates the respective drawbars. B3 percussion is de-activated in this mode, instead the
Perc/EG Mask settings are effective. By means of the Perc/EG mask you may assign percussion
individually to each available harmonic. Percussions always sounds without vibrato and phasing
rotor. This mode may be combined with all generator models. In addition to the H100 model the
following options are available:
H H100 2nd Voice – harmonics selected by Perc/EG Mask sound continuously at full level.
Percussion bypasses vibrato like on the H100. Combined with drawbar voices on vibrato
and 2nd Voice activated this results in a neat chorus effect.
H H100 Harp Sustain – activates the Harp Sustain Effect, 4‘ harmonics fading, polyphonic,
no vibrato. Independent of 4‘ drawbar und 4‘ percussion
Perc/2ndV Vol – percussion volume and 2nd Voice volume.
H E Perc/EG Mask – select harmonics for the
percussion/2nd Voice circuit. Each “o”-symbol represents a
harmonic from 16’ up to Mixture 3. The selected harmonic
that may be activated by turning the encoder is underlined. If activated the respective “o”symbol is filled white.
H E UpperDB Mix1 … UpperDB Mix3 – Upper manual mixture drawbar settings. Mixtures
are made up of up to 3 higher harmonics with their individual levels. Please note: Differing
from the original H100 the HX3.5 provides three mixtures rather than two.
Select Electr Gating (H100 mode OFF) to substitute “mechanical” keying, which generates a key
click, by “soft” electronic keying. This is the way to model the entirely electronic organs of the 80s.
In this mode three additional mixtures are available; the respective drawbars are active. A ADSR
envelope is applied to the harmonics selected by means of the Perc/EG Mask. Set up the ADSR
envelope by using the following parameters:
E Upper Attack – attack time of the upper manual envelope.
E Upper Decay – decay time of the upper manual envelope.
E Upper Sustain – sustain level of the upper manual envelope.
E Upper Release – release time of the upper manual envelope.
E Upper ADSR Hrm – sets harmonic breakup of individual harmonics over time.
In addition, the following options are available for Electr Gating:
E EG Mask to Dry – harmonics selected by Perc/EG Mask are bypassing vibrato and
phasing rotor “dry”.
E EG Mask to Percussion – harmonics selected by Perc/EG Mask are being switched to
ADSR, the EG Envelope Drawbars are enabled as polyphone percussion drawbars.
H E UpperDB Mix1 … UpperDB Mix3 – Mixture drawbars for the upper manual. Mixtures
are made up of up to 3 higher harmonics with their individual levels.
H E Perc/EG Mask – select harmonics for full ADSR envelope instead of simple on/off.
Each “o”-symbol represents a harmonic from 16’ up to Mixture 3. The selected harmonic
that may be activated by turning the encoder is underlined. If activated the respective “o”symbol is filled white.
The fourth keying mode is called Versatile Mode and it is obtained by activating both H100 Mode
and Electr Gating at the same time. In this mode you determine by setting the Perc/EG Mask, if
the respective harmonic is triggered by mechanical keying (OFF) or electronic keying (ON). The
options EG Mask to Dry and EG Mask to Percussion are available as well. The ADSR settings
apply to the harmonics that are set to ON in the mask.
Lower Manual
Scroll downwards starting from the preset/drawbar menu to the vibrato und drawbar settings for
the lower manual. Drawbars settings will be saved as voice presets for the lower manual.
The keying mode setting (mechanical or electronic keying) also applies to the lower manual. In
H100 mode you have three additional mixture drawbars, in EG mode the ADSR settings are
available for the lower manual.
H E LowerDB Mix1 … LowerDB Mix3 – Lower manual mixture drawbar settings. Mixtures
are made up of up to 3 higher harmonics with their individual levels. Please note: Differing
from the original H100 the HX3.5 provides three mixtures rather than two.
E Lower Attack – attack time of the lower manual envelope.
E Lower Decay – decay time of the lower manual envelope.
E Lower Sustain – sustain level of the lower manual envelope.
E Lower Release – release time of the lower manual envelope.
E Lower ADSR Hrm – sets harmonic breakup of individual harmonics over time.
E LowerADSR Ena – select harmonics for full ADSR envelope instead of simple on/off.
Each “o”-symbol represents a harmonic from 16’ up to Mixture 3. The selected harmonic
that may be activated by turning the encoder is underlined. If activated the respective “o”symbol is filled white.
Pedal
Pedal drawbars including ADSR settings are saved to active pedal voice preset.
Pedal Attack - pedal ADSR envelope attack time.
Pedal Decay - pedal ADSR envelope decay time
Pedal Sustain - pedal ADSR envelope sustain level
Pedal Release - pedal ADSR envelope release time (often called string bass “sustain” on
other organs)
Pedal Harmonc – sets harmonic breakup of individual harmonics over time. Set to lower
values to obtain a „picked bass“ effect.
Defaults Group
Step downwards to various default settings; change to desired value by turning incremental
encoder knob. Save changes to current overall preset by pressing knob for more than 2 seconds.
ToneTrimPot – mimics TONE pot on simulated AO28 amp; well, a little bit more on high
values.
TubeAmp Insrt – activates 122 amp simulation, otherwise amp is bypassed. TubeAmp
Gain has no effect if off.
SpkrSim Insrt – activates rotary cabinet simulation, otherwise horn/rotor simulation is
bypassed (recommended for use of external rotary cabinet).
Phasing Upper – activates Phasing Rotor (PHR) for the upper manual (insert effect)
Phasing Lower – activates Phasing Rotor (PHR) for the lower manual (insert effect)
Phasing Mode – selects Phasing Rotor options:
o We/Boe – toggles between Wersivoice (ON) and Böhm Phasing (OFF)
o Ensemble – Strings effect using multiple modulation
o Celeste – deep modulation with feedback
o Fading – slow phasing effect
o Weak – soft modulation, may be combined
o Deep – deeper modulation, may be combined
o RotFast – Rotary effect, fast
o PHR Ramp up – Ramp up effect for rotary slow/fast, may be combined
A slow rotary effect is in place if no option is selected. Weak, Deep, RotFast und RampUp
may be combined with this effect. You obtain two more vibrato effects by selecting We/Boe
and Ensemble or Ensemble and Fading at the same time. These effects may serve as
additional vibrato channel for the H100 emulation, for example.

Split Configuration
Keyboard split default is “pedal mapped to lower manual” on first 25 keys (console organ pedal
range, two octaves). Default split modes may be changed by menu:
Split Manual – switches split mode on or off.
Split Point – sets split point (when split is on) as key number (24 is second „C“ on manual).
Split Mode – default split setting on power-up, engaged when split set to ON.
o
'PedalToLower', map pedal to lower manual up to split point
o
'LowerToUpper', map lower to upper manual up to split point
o
'PedalToUpper', map pedal to upper manual up to split point
o
'LowerToU +1', map lower to upper manual up to split point, transpose lower +1
octave
o
'LowerToU +2' map lower to upper manual up to split point, transpose lower +2
octave
Split point and split mode may also be changed by one of the following procedures:
o Pedal to Lower: Press a single key on lower manual key while switching SPLIT on
to obtain a custom split point (useful for playing pedal bass lines on dual manual
keyboards without bass pedals).
o Lower to Upper: Press a single key on upper manual while switching SPLIT on to
map lower to upper manual up to this key (useful for playing 16’ bass lines or 4’
accompaniment chords on single manual keyboards).
o Pedal to Upper: Press two keys simultaneously on upper manual while switching
SPLIT on to map pedal to upper manual up to highest of both keys pressed (useful
for playing pedal bass lines on single manual keyboards without bass pedal).
o Lower to Upper +1: Press three keys simultaneously on upper manual while
switching SPLIT on to map lower to upper manual up to highest of all keys pressed.
Lower notes range is transposed one octave up (useful for left-hand 8’
accompaniment chords on single manual keyboards).
o Lower to Upper +2: Press four keys simultaneously on upper manual while
switching SPLIT on to map lower to upper manual up to highest of all keys pressed.
Lower notes range is transposed two octaves up (useful for left-hand 16’
accompaniment chords on single manual keyboards).
Generator Group

Updates/Scripts
Update installation instructions and firmware images are made available through our HX3.5
Repository on https://github.com/keyboardpartner/HX35. Follow instructions given on the Github
page.
Setup File – Selection of an update oder setup script from a SD card. For details please
see http://wiki.keyboardpartner.de/index.php?title=HX3.5_DSP-Updates
Factory Reset
To retrieve the factory defaults, press the MenuPanel encoder knob when powering on until
“Factory Reset” prompt appears, then confirm by pressing “up” button. Note: A factory reset will
void your presets.
Serial Numbers and Licences
HX3 is protected against forgery by licence numbers. If not set appropriately after firmware
update, HX3 will refuse to work after 2 minutes. Licences may be re-installed by means of the
HX3.5 Editor at any time.
Please contact KeyboardPartner to obtain a valid licence key. We need your serial number (issued
on startup and by HX3 Editor application) to generate new licences for you.
MIDI Control
The HX3.5 mainboard accepts MIDI key on/off events (default: channel 1 to upper manual, 2 to
lower manual, channel 3 to bass pedals) as well as various MIDI CCs with selectable compatibility
sets. MIDI dynamics slightly affect key click noise. SysEx data other than its own is always
ignored.
Both MIDI jacks act as MIDI inputs with equal priority for connection of two master keyboards or
keyboard and bass pedal. Connecting a third MIDI device requires a MIDI Merge Interface. MIDI
OUT transmits all MIDI CC controller data according to NI B4 standard, independent of selected
MIDI receive CC set.
All HX3 functions that are relevant for the organ player may be remote-controlled by MIDI
commands.
Connect MIDI Out of your MIDI controller or master keyboard to HX3 MIDI input. HX3 does not
introduce any audio latency, so delays are only due to MIDI transmission.
Since MIDI is a one-way interface, HX3 cannot determine the setting of any MIDI controller value
until you touch/use it once. As default, all HX3 controllers are OFF. Do not use any controller
button or drawbar unless HX3 is ready to accept its data; it is a good idea to power up HX3 first
and later your MIDI master keyboard or master controller.
HX3.5 supports MIDI over USB through its USB port connected to a USB host, typically a PC. The
USB connection is also suitable for controlling HX3.5 by the HX35 Editor application, firmware
updates via MIDI SysEx, and DSP updates via DFU data transfer.
The USB port and MIDI IN 2 cannot be used at the same time. Please remove any cable from
MIDI IN 2 before using the USB port.
MIDI CC #7 (default, CC number variable) controls master volume. MIDI CC #11 (default, CC
number variable) controls swell pedal/expression if no expression pedal connected to HX3. If you
use your HX3-attached swell pedal, any MIDI expression message will be overwritten. If the
attached swell pedal is not actuated, MIDI expression messages are accepted.
Note: Some MIDI controllers as well as organ keyboards (like Hammond® XK and SK series)
allow 2nd and 3rd harmonic percussion ON at same time. HX3 implementation regards "2nd ON"
as "Percussion ON" tab in this case.
See Commons Group section to select the desired MIDI CC set. Factory default is Native
Instruments B4, which provides the most versatile command set.
More details including tables of all valid MIDI commands are to be found in the KeyboardPartner
library article “Using HX3 with MIDI controllers”.

How to …
How do I store drawbar settings as preset?
Once you have adjusted the drawbars just keep the rotary knob pressed until “Saved to Preset
#XX” appears on the display. (“XX” representing the current preset number). Drawbar settings are
stored as voice along with the overall preset carrying the same number.
Voices may be selected individually by their numbers. Alter the voice number to recall other
drawbar settings for the manual the voice is assigned to, while all other settings will remain
unchanged as stored in the preset. If you recall the preset the voice will regain its former settings.
How do I copy a stored voice to another preset?
In the menu, select the voice to be copied. Keep the rotary knob pressed until “Save Voice to
Preset #XX” appears on the display. (“XX” representing the target preset number). Turn the rotary
knob to select the target preset number to desire. Press the rotary knob until “Saved to Preset
#XX” appears on the display.
How do I copy a stored preset to another preset?
Press the rotary knob twice to navigate to the preset/drawbar menu. Select the preset you wish to
copy. Keep the button pressed until “Save Preset #XX to #XX” appears on the display. (“XX”
representing the current preset number and the target preset number, respectively). Turn the
rotary knob to select the target preset number. Press the rotary knob until “Saved to Preset #XX”
appears on the display.
How do I access the General MIDI instruments?
In the menu, select the voice for the manual you wish to assign a GM instrument to. Turn the
encoder knob to select a voice number in the range of 16…39. These are the available GM voices,
which may be preassigned using the HX3.5 Editor. You may store the selected GM voice as
preset just like the drawbar settings. However, the GM voice will retain its voice number.
How do I store my TubeAmpGain setting as preset?
You may store the TubeAmpGain setting as well as any other effect parameters as part of the
active preset by simply keeping the rotary encoder knob pressed until “Saved to Preset #XX”
appears on the display. (“XX” representing the current preset number). However, Rotary Motor
ON/OFF and Rotary FAST ON/OFF are always live and not part of a preset.
In which way does the live preset 0 differ from other presets?
Traditionally, the live preset 0 is not a real preset, but instead applies the current “live” settings of
the drawbars and control switches. If you select a preset different from 0, your live settings will
remain stored. If you return to preset 0, the live settings will be recalled and the current drawbar
settings will be applied. In addition to that, the HX3.5 preset 0 preserves other parameter settings,
which are cannot be set “live” by drawbars or other controls. It also determines the power-up
settings.
