The newly redesigned Multifilter 2 adds a ton of functionality to Toppobrillo's old filter.
Dual input crossfading mixer with voltage controlled gain and saturation.
Dedicated "Ping" input percusses the filter.
Variable Mode output: continuously-variable voltage controlled response with selectable NP (Notch) or BP at center.
Variable response can track frequency for some interesting sweep variations and modulation options.
Voltage controlled resonance, or "Q".
Self-oscillates reliably over entire range- doubles as a very playable audio source or LFO with multi-phase outputs.
Tracks V/OCT over roughly 4 octaves.
Fully buffered outputs and low noise design.
