Modulation

The source families available from Add Modulation Source, MIDI Learn, and OpenSoundControl Learn, one tab each. See Modulation Matrix for how a source gets assigned to a parameter in the first place.

LFO	A repeating or one-shot waveform generator, 12 waveforms including 6 noise types.
Envelope	An ADSR envelope, triggered by a MIDI note, an audio threshold, or another LFO’s phase.
Time	A monotonic accumulator: rises or falls at a steady rate, unbounded.
Macro	A named, freely assignable value, bindable to a MIDI CC.
Audio-Reactive	Live audio level: L/R, 8 named frequency bands, or 4 user-defined bands.
CV/Gate	Up to 12 channels of external control voltage / gate input.
MIDI	CC values.
MIDI Note	Velocity, Aftertouch, Pitch Bend, and NRPN.
OpenSoundControl	Address-based UDP input.
