Capabilities 1

Voltage-Controlled Oscillatorvco
Digital VCO implementing three synthesis algorithms (VOSIM, summation synthesis, phase modulation) with dual pitch control and four tone controls.251

Jacks 4 — 3 in / 1 out

NameSignalVoltageDescription
Inputs (3)
Pitch Acv0V to 8V1V/octave pitch input for oscillator A; cross-normaled with Pitch B input.251
Pitch Bcv0V to 8V1V/octave pitch input for oscillator B; cross-normaled with Pitch A input.251
Synctrigger≥2VResets the state of the oscillators on a rising edge; used for sync modulation. Added starting at serial 700.251
Outputs (1)
Outaudio—AC coupled audio output.251

Parameters 10

NameTypeRangeBehavior
Algorithmswitch—Selects which of the three synthesis algorithms is used: VO (VOSIM-based), SS (summation synthesis), or PM (phase modulation).251
Dampknob—A tone control. Behavior is algorithm-specific; consult per-algorithm documentation.251
Foldknob—A tone control. In all modes controls the threshold of the wavefolding.251
Masterswitch—Controls sync between the two oscillators. Middle position: both free-running. A position: oscillator B syncs to oscillator A. B position: oscillator A syncs to oscillator B.251
Modknob—A tone control. In all modes controls phase modulation between the two pitch oscillators.251
Morphknob—A tone control. In all modes controls the waveform of the oscillator, continuously varying between sine, triangle, and saw.251
