Erica Synths Black Polivoks VCF Filter

The Erica Synths Black Polivoks VCF is an genuine emulation of the notorious Russian Polivoks. Included in the modules circuit are the original K140UD12 Russian ICs.

Black Polivoks Demo

Erica Synths Black Eurorack Modular Demo from Perfect Circuit Audio on Vimeo.

For this patch, the main sound source is the Black Wavetable VCO, from Erica Synths, with the Main out and the Suboctave out patched into the Black Crossfader. The out of the crossfader is then patched into the Black Polivoks filter and then into the Black VCA. A little bit of delay is added from the Alright Devices Chronoblob. The sequencer being used is the Malekko Voltage Block, which is being clocked by the 4MS Quad Clock Distributor. Outputs from the QCD are also triggering two Black HADSRs, both of which are controlling the VCA at different times. The Black Octasource is providing modulation to the Shape input on the Wavetable VCO and the filter cutoff, with the Intellijel Planar changing both the mix of the Crossfader as well as the modulation shape of the Octasource. The Black modulator is slightly modulating the rate of the Octasource as well.
