Contents
This upgrade adds three Banks with 18 presets and 23 new modules to the 4000 or 4500. 4000 users
without the optional sampler (standard in the 4500) will see sampler presets in Banks 32-34 but will
not be able to use them.
The Ultrashiftertm is the first of a new generation of pitch shifters specially designed for vocal use. It
may give interesting results on other material but this cannot be guaranteed.

Presets
95 Ultrashifter Presets
1. Ultra AutoCorrect
This preset is a diatonic ultrashifter set as a pitch corrector, allowing you to choose which of the 12
notes are to be quantized (corrected). There is a meter displaying your source (input) as well as the
output of the analysis correction.
A diatonic pitch shifter shifts the musical pitch of an audio signal while maintaining the proper harmonic
relationship to a desired key. The pitch shifter takes care of finding out what note is being played and
automatically adjusts the amount of pitch shift so that the shifted note remains in key. Alternatively, it could be
viewed as ‘quantizing’ the pitch, or ‘pulling’ it to the nearest note in the scale.
A normal or non-diatonic shifter will shift each note by the same interval, putting some notes out of key.

2. Ultra Cents
This preset allows you to choose the amount of shift as a value in cents (100 cent to a semitone). It
has an automatic  parameter, which will get you in the ballpark, but you should be aware
that all signals are different and the automatic value is meant only as a guideline. The automatic
formant value will be displayed, allowing it to be manually overridden, but will revert to its automatic
formula as you change the shift amount. So - choose the shift amount first, and then fine tune the
 value for best results.
3. Ultra Cents 2
This preset is the same as 'Ultra Cents,' but has an purely manual  parameter.
4. Ultra Interval
This preset is similar to 'Ultra Cents,' in that it has an automatic  parameter, but differs in
that the shift amount is set as an interval. Note that the three Interval presets are non-diatonic and
therefore will not keep an interval within a 'scale' - for example, shifting up a 'perf5' means that the
output will always remain 700 cents above the input.
5. Ultra Interval 2
This is the same as 'Ultra Interval,' but has a manual  parameter.
6. Ultra Interval 3
This version adds the  and  parameters, giving possible formant and tuning
values for each possible interval choice over the entire range. These allow you to pre-select the
perfect formant and tuning for each interval, enabling you to vary the interval on the fly and know
that the color of each will sound as consistent as possible.

Presets
7. Ultra Diatonic
This preset has an automatic  parameter. Being diatonic, it allows the chosen  to
remain in the selected scale and key. There is also a  parameter, which allows you to select
scales that are not equal tempered.
8. Ultra Diatonic 2
The same as 'Ultra Diatonic,' but with a manual-only  parameter.
9. Ultra Diatonic 3
The same as 'Ultra Diatonic,' but this version adds the  and  parameters.
10. Ultra UserScales
This version has an automatic  parameter. In an effort to keep these presets unencumbered
with too many parameters, we split off these three 'user scale' presets for those who want to create
their own custom scales. To define a scale you must use at least five or more notes where the first
becomes the 'key'. They must be in ascending order within an octave range from lowest note to the
highest. If there are less then five notes, or more than seven, the user scale will be ignored and a
major scale interval pattern used. You have been warned !
11. Ultra UserScale 2
This is like 'Ultra UserScale,' with a manual  parameter.
12. Ultra UserScale3
This version has the  parameters.
13. RoboticVoice
This preset requires a shift amount in cents. There is a manual  parameter, with, in the
addition, a  parameter. This new parameter reduces the possible range of inflection, giving a
machine-like character to the output.

Ultrashifter preset parameters:
 

this chooses the amount of shift, expressed in cents or as an interval,
depending on the preset..



The wet/dry signal mix.



The amount of delay on the shifted signal including the built-in 50mS
processing delay.



The amount of delay added to the dry signal. Note that setting this higher
than  makes the shifted voice occur first, tricking the ear when you
are adding harmonies.

Presets


The combined left/right panning of shifted and dry signal. 100%=shift
left/dry right.



A percentage value that will globally alter the formant or 'character' of the
shifted signal.



A percentage value that alters the formant for a specific interval chosen.



In non diatonic 'Interval' presets, this is an global offset added to the
 parameter.



The final displayed value of  and ,  and
, or the cent value of an  selection.

source
 

Optimises the shifter by selecting upper and lower (source) limits.



The type of source material. Default, Male Speaking, Male Singing, etc.
This gives an automatic selection of   params.



Can be used to tune the vocal characteristics for troublesome material such
as telephone or radio sources.

scale/calibration


In a diatonic shifter, this is the amount below which no quantization or
‘pulling’ of the note occurs.



How fast quantization responds in a diatonic shifter. Measured as mS per
100 cents.



Selects the type of scale desired.



Selects the first or tonic note of the scale.



Selects the type of tempering. Our normal western tuning is equaltempered, where the octave is split into 12 equal steps of 100 cents each.
This control allows other schemes to be selected.



In diatonic presets, this chooses the pitch of A= measured in Hz (The
normal modern standard is A-440).



Portamento, or how much time it takes to glide from one interval to
another, measured as mS per 100 cents. The greater the change, the longer
it takes to get there.



In the ‘AutoCorrect’ preset, this parameter allows you to choose whether
or not you want to quantize (correct) for each of the 12 notes,

Presets


In the 'UserScale' presets, this is where you create your scale.

96 Midiclock Presets
1. Midiclock Test
This is a simple program to illustrate the use of the MIDICLOCK module described on page 14.
2. Midiclock Delays 2640
These bpm style delays have stereo input and output. Midiclock sets the bpm, and you select a note
value for each delay as a rhythmic value (whole note ~ 1/32 note) which is then also displayed as a
time in mS. Global ,  and  parameters make control easy, while the
 parameter lets you set the glide speed so that tempo changes can be glitch free.
3. MidiClock FM Panner
This stereo panner is extremely easy to use and very colorful. 'FM' refers to frequency modulation,
which is where one lfo (low frequency oscillator) modulates the frequency of a second lfo. To tune it,
you select a  for the panning (which is then also displayed as a frequency value in Hz), an  parameter selecting the amount of secondary modulation and lastly the  or frequency
of the secondary modulation, also as a rhythmic value. It is a great way to spice up foreground or
background tracks.
4. MidiClockTremPong
This one combines a tremolo effect (selected as a rhythmic value) with a simple but powerful delay
scheme. The delay consists of a predelay feeding the ping-pong, which has a clean feedback path
outputs through a pair of ring modulators. You choose the delay time as a rhythmic value and the
pre and  times are displayed as time values in mS. Because of the structure, the first
delay heard is twice the time of the subsequent 'pongs'. The  and  params are set up
for a natural chorus or beating effect to color the delays. The result is very easy to use, and a
powerful combination effect.

97 Dither Presets
1. Dither Test
This simple program allows you to dither its output to 16,18 or 20 bits. Either rectangular or
triangular dither may be selected. Preset designers may want to include this program’s functionality as
part of a larger preset, especially for mastering purposes.

C_MASTER

GROUP: CONTROL MATH

Master control math scaling module

mst

v2.2

This module allows a single knob to generate a number of linked outputs, each one of which has a different relationship to the input. The aim of this
module is to allow a single knob or input to control many different parameters in a controllable way.
The variable number of outputs are scaled numbers, between outStartN and outStopN (inclusive) based on the input's position between inStart and
inStop (inclusive). OffsetN is added to the result, which is then forced between the boundaries of outStartN and outStopN for outputN. Thus as the
input traverses its full range (between inStart and inStop) each output will traverse its full range (between outStartN and outStopN) with an optional
OffsetN.
As an example, if the input is at instart, the value of output3 will be outstart3 + offset3. If this value is lower than outstart3 it will be set to outstart3,
similarily if is is higher than outstop3 it will be set to outstop3.

GATE2

GROUP: DYNAMIC

Audio Noise Gate with sidechain input.

gat

This module implements a noise gate function with a separate sidechain input, allowing the dynamics of one signal to control another. This feature will
typically be used to remove background noise resulting from processing, with the sidechain input connected before the process, and the signal input
being the processed signal.
If the sidechain input is below a specified threshold it will silence (gate) the output. Adjustable attack and release times control how fast the gate will
turn on or off. Suitable use of these makes the gating function much less audible.

SCALES

GROUP: MISCELLANEOUS

scl
This module implements an advanced version of diatonic pitch shifting and pitch correction. It will determine the pitch shift required to stay in key
given a desired interval and will also determine the shift needed to correct an out of tune note. It does this by using the given pitch to determine what
note of the current scale is being played. It will then use this information along with the selected scale, interval tuning, etc., to figure out how much
pitch shift to apply.
This module is part of the diatonic processing for the UltraShifter(tm). It performs processing which is used by the ultrashifter module and as such is
unlikely to be useful by itself.

Controls how much the pitch may move outside the range of the
current note before the current note is changed to reflect that pitch.
Hystersis can prevent the oscillating between adjacent notes that can
occur when the pitch is in between two notes. Notes are typically 100
to 200 cents apart so 50 cents of hystersis would allow the pitch to
wander a lot before a higher or lower note was recognized.
Controls how rapidly the pitch is corrected to bring it into tune. The
numeric value gives the time for the pitch to change 100 cents. Actual
pitch correction values will be much less than 100 cents and hence
will be performed more rapidly.
Controls the smallest error in pitch that will be corrected - if the pitch
deviates from a true note by less than this amount, no correction will
be made. This value may be used to let vibrato through or to enable
correction only on notes that are badly out of tune.

ULTRASHIFTER

GROUP: PITCHSHIFT

Formant Correct Pitch Shifter

ush

This module can pitch shift a vocal two octaves up or one octave down while maintaining a natural vocal quality. It can also alter the overall formant
structure of a vocal signal independently of any pitch shift. Ultrashifter is optimized for vocal signals although it may be suitable for other monophonic
source material.
Due to the extensive processing performed by this module, the input signal will be delayed a total of 50 milliseconds (a delayed dry signal is available
for mixing in the 4000). By comparison, Eventide’s other pitch shifters typically delay the signal 20-25mS.
This module must be connected to the sourceanalyzer module in order to function. The combination of these two modules will use ALL the available
DSP power on a 4000 - no other signal handling modules can be added. However, a simple mixer is included for wet/dry mixing and panning.
The Orville version omits the mixer but has a number of other enhancements and thus the combination uses about 50% of an Orville DSP.
This module is very complex and is intended for experts only. The less experienced user may be well advised to tweak the existing presets, rather than
trying to build new ones. Note that the Orville and 4000 versions are NOT compatible - a 4000 Ultrashifter(tm) program will NOT run on an Orville.
