About
The so called "klangboard" is a recycled ps/2 keyboard in combination with a awesome mozzi library for the arduino microcontroller. It contains 2 osc with different waveforms and a lot of other functions - and for mobile playing a builtin amplifer. For everybody who never learned guitar playing and is a pro in the touch-typing system/method is this the perfect instrument.
