OT now, but if you're intending to run more than a single MIDI in our
out on Arduino things might get somewhat more complicated than they
seem. Arduinos I/O is fine for a single MIDI channel (hence the
countless Arduino monophone MIDI synth projects) but will quickly get
to its limits with more demanding stuff. Expect nasty jitter and timing
problems unless using a dedicated UART.
