haxo-ino is an Arduino/C++ port of haxo-rs by @cardonabits to run the Haxophone. It is narrower in scope than haxo-rs in that its only goal is send MIDI commands out over USB to a host device; there is no audio being sent to the Haxophone's 3.5mm headphone jack. Since the system runs on a microcontroller, the MIDI controller is ready ~2 seconds after being plugged in, rather than the ~2 minutes needed to start the system up the Pi Zero.
