Sculpture Jitter generators
Many sounds can benet from small, random modulations to parameters. These can emulate the
subtle variations that occur when particular instruments are played.
The two jitter generators are special LFO sources that are 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.
Note: Jitter modulation of pickup positions as the target produces great chorus-like eects.

Rate knobs: Rotate to set the speed of the modulation (jitter) signal for each jitter generator.
•
Jitter On/O buttons (1 and 2): Turn each jitter generator on or o, independently.
•
Target 1 and 2 pop-up menus: Choose modulation targets 1 and 2, for each jitter generator.
•
