Polivoks Generator circuit. Sawtooth-core VCO with 1V/octave tracking, manual octave switch, voltage-controllable pulse width modulation, and both linear and exponential frequency modulation. This is a unique analog suboctave divider circuit, used in the Soviet "LIDER" guitar floor effects unit. This design is different from most octave effects because the divided signal has a strong resemblance to the input, instead of a square wave. A wet/dry mix control and a stability filter have been added for modular convenience and deviant audio behavior.
