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.
