All analog state variable filter with lots of versatility and juice. High, band, and lowpass simultaneous outputs. Resonance is uncompensated and when cranked will get loud to the point of overdrive and clipping.

There are three CV inputs that control the cutoff frequency and one that controls resonance. CV1 and REZ are adjusted such that a 5 volt signal (likewise +/-2.5 volts or -5 volts) will give a full sweep of the parameter. CV inputs 2 and 3 have a very rough 1V/oct response.

With modest resonance, a trigger/gate/hard-edge-waveform at the input will excite the filter into bursts of self oscillation, and awesome bongo/tom/kick drum sounds ensue. With resonance maxed, the module self-oscillates and can be used as a sine wave VCO.

Update notes: This module is now called VCF 2164 based on the IC inside. The core circuit is virtually unchanged but it has been marginally improved here and there. The biggest changes include better overall circuit protection and improved mechanical strength.
