Gordon Monahan uses fruits, vegetables, and a jar of sauerkraut as voltage controllers for a software synthesizer built with ppooll-max/msp and an arduino interface. Performed live at the Subtle Technologies Festival, on board a cruise ship in Toronto Harbour, June 5, 2010.

The Sauerkraut Synthesizer is based on a technical prototype using lemons (The Lemon Synthesizer), developed as a collaboration between Gordon Monahan, Akemi Takeya, and Noid, in Vienna, March, 2009.
