Random Variations
Many sounds can benefit from the use of random modulations to parameters. These
can emulate small variations that occur when particular instruments are played.
Jitter 1 and Jitter 2
The two jitter generators are special LFOs, designed to produce continuous, random
variations—such as those of smooth bow position changes. The jitter generators are
equivalent to general purpose LFOs set to a noise waveform.
To activate the routing of the jitter generators, click on the 1 or 2 buttons.
Note: Jitter modulation of pickup positions as the target produces great chorus-like
effects.
 Rate knobs: These knobs set the speed of the modulation (jitter) signal for each
respective jitter generator.
 Target 1 and 2: These menus define modulation destinations 1 and 2.
 Amount 1 and 2: These sliders determine the amount of modulation for each jitter
generator.
Note On Random
The two note on random generators are intended for random variations between
different notes/voices. Their values are randomized for each note, and remain constant
until the voice is released. Such randomizations are useful for adding interest/
thickening the sound when played polyphonically. It is also useful for emulating the
random variations a player introduces when playing an instrument—even when
repeating the same note.
