NameSignalVoltageDescription
Damp cv 0V to 5V Tone control CV input; behavior varies by algorithm. [8]
Fold cv 0V to 5V Tone control CV input; in all modes controls the threshold of the wavefolding. [8]
Mod cv 0V to 5V Tone control CV input; in all modes controls phase modulation between the two pitch oscillators. [8]
Morph cv 0V to 5V Tone control CV input; in all modes controls the waveform of the oscillator, continually varying between sine, triangle and saw. [8]
Pitch A cv 0V to 8V 1V/octave pitch input for oscillator A; cross-normaled with Pitch B input. [8]
Pitch B cv 0V to 8V 1V/octave pitch input for oscillator B; cross-normaled with Pitch A input. [8]
Sync trigger ≥2V Resets the state of the oscillators on a rising edge; used for sync modulation. Added starting at serial 700. [8]

NameTypeRangeMin FWBehavior
Algorithm switch [8]
Damp knob Tone control knob; behavior varies by selected algorithm. [8]
Fold knob Tone control; in all modes controls the threshold of the wavefolding. [8]
Master switch Controls oscillator sync: middle position = both free running; A = oscillator B syncs to A; B = oscillator A syncs to B. [8]
Mod knob Tone control; in all modes controls phase modulation between the two pitch oscillators. [8]
Morph knob Tone control; in all modes controls the waveform of the oscillator, continually varying between sine, triangle and saw. [8]
Pitch A knob Coarse and fine knobs offset the pitch of oscillator A; also controlled by 1V/octave CV input. Cross-normaled with Pitch B. [8]
Pitch B knob Coarse and fine knobs offset the pitch of oscillator B; also controlled by 1V/octave CV input. Cross-normaled with Pitch A. [8]
Voltage supply selector menu_setting Selects whether the processor runs from the 5V or 12V Eurorack power rail. Running on 5V reduces noise and load on the 12V bus. [8]
