Erica Synths super-enhanced Polivoks VCO uses the core of the original Polivoks VCO, but has plenty of modifications to adjust its performance to modular synth standards. 


Modifications:

  • Changed CVs to Eurorack standard 1V/Oct (original has inverted CVs)
  • Made all CV ins buffered in order to eliminate crosstalk and undesired detune (very few DIY kit producers buffer CV ins - mostly they are just summed on resistors). As result the VCO is surprisingly stable and tunes well.
  • Made optional adjustments to output signal amplitudes and offsets - you can have the original output signals (they are totally different waveform to waveform) or make them standard 10Vptp
  • The original Polivoks has an interesting peak in the triangle waveform - we introduced an optional filter to eliminate it or leave as it is
  • Significantly updated the pulse wave circuit and introduced PWM - it sounds insanely great!
  • Frequency range: from LFO to C8
  • Available output waveforms: triangle, saw, 4x pulse
