Velotone - bicycle powered sequencer/synth

This was made for Paddy Austin, who organises bicycle-powered club nights where all of the lights and sounds are generated by pedal power. A magnet attached to the rear wheel passes a reed switch, which sends a pulse to an 8-stage sequencer mounted on the handlebars. Depending on the speed of the cyclist, the sequencer plays 8 tunable oscillators, and also controls a Coron DS-7 drum machine. Paddy and Charlie sent me the video - thanks very much!
