This library allows an Arduino board with USB capabilites to act as a MIDI instrument over USB. The library is based on PluggableUSB, so is only compatible with IDE 1.6.6 and nightly builds (AVR core > 1.6.8, SAM core > 1.6.4, SAMD core > 1.6.1)
Furthermore, since PluggableUSB only targets boards with native USB capabilities, this library only supports these boards (eg. Leonardo, Micro, Due, Zero and so on)

Test procedure (Linux)
Load the correct driver (
sudo modprobe snd_seq_midi)
Flash the board with
MIDIUSB_loop example, then execute
the output will be something similar to
Port Client name Port name 0:0 System Timer 0:1 System Announce 14:0 Midi Through Midi Through Port-0 20:0 Arduino Micro Arduino Micro MIDI 1
20 is the one we’ll use in the following examples.
fluidsynth inside a shell with a
fluidsynth --server --audio-driver=alsa -o audio.alsa.device=hw:0 ~/Synth.SF2
In another shell, execute
aconnect 20 128
to connect our MIDI device with fluidsynth
aplaymidi --port=20:0 ~/some_midi_file.mid
and the file will be played after a complete roundtrip to the board.
