Better yet, keep your Italo disco. Here’s some actual Krautrock. Yes, It’s the Sauerkraut synthesizer, the work of one Gordon Monahan.

Gordon Monahan’s Sauerkraut Synthesizer is an experimental synth, built around fruits, vegetables, and a jar of sauerkraut as voltage controllers for a software synthesizer, built with ppooll-max/msp and an Arduino interface.
The video captures a live performance on the Sauerkraut Synthesizer 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.
