MIDI in and out work fine on a traditional UART. The baud rate is 31 250,
which works out perfectly when using an crystal that is an exact number of
MHz (as opposed to some funny number).

However, rather than using conventional RS232 levels, proper MIDI uses an
opto-isolated connection.

I believe you can do it with 1
