Sculpture Jitter generators in Logic Pro for iPad
Found in the Random Variations 1/2 sections of Sculpture are two jitter generators.
These special LFO sources 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.
Many sounds can benefit from small, random modulations to parameters. These can emulate the subtle variations that occur when particular instruments are played.
Tip: Jitter modulation of pickup positions as the target produces great chorus-like effects.
Random Variations parameters
The two Random Variations sections provide two jitter generators, for a total of four potential modulators when fully utilized.
Jitter 1/2 Bandwidth knobs and fields: Set the speed of the modulation (jitter) signal for each jitter generator.
Target 1/2 On/Off buttons: Turn each jitter generator on or off, independently.
Jitter Amount 1/2 knobs and fields: Determine the amount of modulation for each jitter source.
Target 1/2 pop-up menus: Choose modulation targets for each jitter generator.
