Over at MAKE: Japan, Takumi Funada found this fun-looking open source hardware instrument called RakuChord Mobile. Instead of just generating simple tones, this project by Japanese Arduino enthusiast Ina is polyphonic, and allows a user to play both a chord backup line and melody at the same time. Google translate didn’t seem to work on the XML project page, however both the source code and schematic are available there.
