Erica Synths Black Polivoks Eurorack System

Product Description

The Erica Synths Black Polivoks Eurorack System is a Polivoks-inspired 84HP two-VCO modular system with 55 patch points that go well beyond classical monosynths.

This system has a full analog design, powerful VCOs with sub oscillators, versatile modulation sources and signature Polivoks filter makes Black Polivoks System great production and live performance tool with a sound that definitely stands out.

System includes:

• MIDI-CV Module - emulates classical monophonic and duophonic synth behavior and and has nice bonus features – clock output, configurable modulation output and analog glide
• The Balck Modulator - fully analog modulation and noise source. It consists of LFO/audio frequency oscillator with three simultaneous waveform outputs, Zener diode-based noise generator with three noise flavors and clockable S&H circuit.
• The Black VCO - analog VCO with four simultaneous waveform outputs and one octave down sub-oscillator. The core of the VCO is borrowed from famous Russian synth Polivoks VCO and in an exponential converter, Erica uses the original matched transistor IC that was used in Polivoks.
• The Black Polivoks VCF - one of the most authentic-sounding emulations of the famous Polivoks synth. The original Russian ICs K140UD12 are used in the sound circuit and you get punchy bass sound and very smooth controls.
  
• The Black Envelope Generator - compact, full analog envelope generator with gated loop and gate delay for nice acid basslines and very slow drones.
• The Black VCA - unique design, hi-fi level VCA with improved attenuation and CV reject levels, and bias control for great tremolo effects. Smooth fading between linear and logarithmic response allows you to create versatile percussion sounds while an LED bar graph gives visual feedback on the output level.
