MIDIUSB

Version: 

1.0.3

Description: 

Allows an Arduino board with USB capabilites to act as a MIDI instrument over USB.

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 aseqdump -l; 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

Port 20 is the one we’ll use in the following examples.

Start fluidsynth inside a shell with a soundbank

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

Then, execute

aplaymidi  --port=20:0 ~/some_midi_file.mid

and the file will be played after a complete roundtrip to the board.
