Arduino Micro - MIDI Controller
It uses the Arduino Micro as USB midi controller. It has 1 capacitive touch octave (12 Keys), 2 rotary encoders, a button, and a proximity sensor that can be used as a mod wheel, sustain pedal or MPE.
The oled screen displays the different configuration options. It can be set to any channel or C.C. so it can be used to modify other instruments behavior. The capacitive touch keys can also be used as 12 drum machine pads.
