Polivoks VCG Oscillator - 12HP


The Polivoks VCG is a classic analog voltage-controlled oscillator with a sawtooth core and 1 volt/octave response. Features saw, triangle, and PWM outputs and a plethora of modulation inputs. Both linear and exponential FM are available, and the frequency control has an octave switch. This design is fully calibrated and thermally stabilized, and boasts an aggressive modulation character despite its stability. The triangle waveform is particularly characterful.

This device is part of the IRON CURTAIN ELECTRONICS system and is created in collaboration with Vladimir Kuzmin, the designer of the original POLIVOKS synthesizer. The module uses original Soviet integrated circuits in the exponential converter and temperature compensation circuits to preserve the character of the Polivoks design.
