A polyphonic dual highpass/lowpass filter offering the aggressive tones of a classic 70s Japanese monosynth in a polyphonic version. Its uniquely raunchy sound totally transforms the overall tonality of Voltage Modular! The highpass and lowpass sections can be used in series, as with the original instrument, or as two independent filters, or mixed together in a number of ways, and we've included extensive CV inputs for parameter control. We carefully A/B'd the VCF-20 Filter with an original instrument with the coveted "version 35" filter and we think you'll be delighted with its authenticity.
