The VCO-13 is a superwave oscillator.
The octave button changes the base frequency in octave increments and has a range of 4 octaves.
The tune knob changes the base frequency by +/- 12.00 semitones.
The wave button changes the waveform to sine, triangle, or sawtooth.
The detune knob detunes the 7 internal oscillators.
The scale knob varies the frequency modulation amount from 1-10 octaves.
The mix amount knob blends between 1 and 7 internal oscillators.
Frequency modulation input.
Keyboard note value input in 1 volt per octave.
Mix modulation input.
Sine, triangle, sawtooth
MIDI note C0 (16.35 hz) to C9 (16.74 khz)
+/- 10 octaves
The VCO-13 has 7 internal oscillators.
Each oscillator is slightly detuned from one another which creates a full rich sound.
