R Scott’s analog MIDI drum machine puts circuitry from an old organ’s rhythm section under digital control –
The 8 knobs on the top of the case control Master Volume, Kick, Clave, Snare, Conga, Low Tom, High Tom, and Hi-Hat levels. The two LEDs indicate power and midi activity.
The drum sound circuitry was taken from a broken old Farfisa organ. I removed the entire rhythm accompaniment assembly and later built a power supply for it, turning it into a stand-alone drum machine.
MIDI control was implemented via a custom kit from Highly Liquid. Combining pre-existing analog synth boards with new controller hardware is an awesome idea that coud be applied in a number of creative ways. Head over to the site to hear samples and get more of the story – analog MIDI drum machine
