The Mod (modulation) controls let you easily create sophisticated modulation settings for shaping a Part. Modulation wheel and pressure (aftertouch) can be used as modulation sources.
Normally, the modulation wheel provides a periodically repeating modulation such as vibrato, and aftertouch provides a static offset to the selected destination such as volume or filter swells.
