- Filtomika Module is a monophonic filter effect module that emulates Vladimir Kuzmin's "programmable op-amp" filter as designed for the 1980s Polivoks analog synthesizer. The original filter design has been enhanced here with new controls like Starve, Filter Drive, and Amp Drive, as well as new highpass, notch, and peak response filter modes. It is available as part of the Cherry Audio/MRB Filtomika Module Collection for Voltage Modular.
