the filterbank is an excellent musical processing device for creating filter sweeps and effects or damaging your sound for even cooler effects! it's a 12 or 24db/octave 4-pole dual filter module with one signal input and two audio outputs. the filters can be dual mono or linked, with crossfading from hi-pass to low-pass filtering with lfo and adsr modulation. the filter is genuine analog circuitry with serious overdrive for the grungiest of sounds! what's new in the filterbank 2 are five three-way toggle switches which have been added to the front panel as well as an optional foot controller jack in the back for controlling filter cutoff or bypass switching.
