Our Erica Black Polivoks VCF is one of the most authentic sounding emulations of the famous Russian 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.
Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, we did not economise on the module width, we put design and usability first. Big knobs are assigned to functions that make difference in sound. The Erica Black series are a range of modules that together make an entire synthesizer.
