About this item

  • Triangle, saw and pulse wave outputs
  • Manually adjustable and CV controlled pulse width
  • Great tracking across 8 octaves
  • Exponential FM input with attenuator
  • Synchronization input


The fully assembled module.The core of the VCO is borrowed from the famous Russian synth Polivoks VCO and in exponential converter we use the original matched transistor IC that was used in Polivoks.Features:Triangle, saw and pulse wave outputsManually adjustable and CV controlled pulse widthGreat tracking across 8 octavesExponential FM input with attenuatorSynchronization inputOctave switch – 5 octavesSkifffriendly designWe have significantly updated schematics:Introduced +10V regulators for greater stability of operation,Adjusted signal amplitudes to match requirements of contemporary modular synths and made all output signals available simultaneously,Redesigned CV inputs to accept positive CV signals,Introduced PWM circuit with manual and voltage controlled pulse width,Introduced synchronization input, so you can sync the VCO to other VCOs.Technical specifications:Audio output amplitude: 10VptpOctave range: C0 – C8Panel width: 12HPModule depth: 35mmPower consumption: 34mA@+12V, 36mA@12V

The 1v/Oct is a huge pain to adjust, and even after warming up for half an hour or more, then putting it on a meter for several hours, trying to adjust the travel between octaves, etc.. it just doesn't maintain the tracking. You will go up a semitone at each octave, minimum. It has decent sound, but the tracking is hard to deal with. I guess it's a good drone oscillator.
