Erica Black Polivoks VCF on Modulargrid
Authentic emulation of famous Soviet Polivoks synth VCF circuit with extended cutoff knob and eliminated clicks.
This is one of the most authentic sounding emulations of the famous Soviet synth, the Formanta Radio Factory Polivoks.
The original Russian ICs K140UD12 are used in the sound circuit. We did several updates to adapt the VCF for contemporary modular synth demands. Independently buffered inputs, extended Cutoff knob, eliminated clicks, when switching filter modes, and output stage added to eliminate signal inversion. The result is a much punchier bass sound and very smooth controls.
