This was made for Colin Cloughley, creator of fine industrial techno.

Knobs, L-R: keyboard filter mode select (LP, BP, HP), cutoff, resonance, LED sensitivity, instrument pitch, drum pitch.

Sockets L-R: filter control voltage in, external lowpass in, bandpass in, highpass in, keyboard out, keyboard out via filter.

The switches in the centre connect the circuit bent modifications.

The video contains sounds generated by the SK-5 alone, except for the very last clip where the filter is being modulated by an external LFO.

The filter was made from Ken Stone's Synthacon VCF schematic. Please visit Ken's amazing website for an incredible collection of useful information, and PCBs for sale:
