Circuit Bent Casio SK-5 with CGS Synthacon Filter

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:

Ken Stone's synthacon filter is f*cking amazing......

[thenervoussquirrel]

Yes, it's great! Anyone who hasn't already done so, check out Ken's website.

The idea behind the video is more about just getting a quick glimpse of what the project was about - I'm sure there won't be a DVD or cinema release.

It's difficult to find the time to stop and document the instruments anyway, without getting tied up in recording them perfectly.

I have no idea what I'm doing sat here typing in the YouTube comments section.

Really nice work... How did you implement the filter?

[thenervoussquirrel]

The keyboard is fed into a selector switch, which can be set to either the LP, BP or HP input on the filter. There is a socket to bypass the filter if you want to hear the keyboard on its own, or you can bypass the keyboard if you want to use the filter on its own.
