The Sherman Filterbank is a powerful analog filtering and distortion unit with a huge frequency range and a killing TUBE overdrive behavior. It's Easy and FUN to use, live and in the studio processing every sound source, effect mixing, expanding modular systems, etc. - Independent low pass, band pass and high pass filters with resonance, frequency and ADSR (positive - negative) controls - These are switchable between parallel or serial - The second filter has a 6 octave switch, and is synchronizable with the first filter - 1 ADSR generator for these filters with an external output for use with more filterbanks or modular systems, triggered by the incoming signal, by a second sounds source, or by a gate - 1 FM input for the filters, internal or external audio, LFO or CV - 1 VCA overdrive with AR generator also - 1 ring modulator input, internal or external audio, LFO or CV
