TIMBRE knob
The controls the VCO’s wave shape to alter its harmonic content.
The slope and pulse width vary simultaneously in a trapezoidal shape.
The effect on the waveform is illustrated in the diagram to the left.
TIMB. CV jack
Patching a CV input to this jack has the same effect as turning the TIMBRE knob.
Both the knob and the jack can be used simultaneously.
TIMB. CV responds well when controlled by an envelope or LFO, adding smooth
modulations to the VCO waveform’s harmonic content.
