One hopes not. If memory serves, MIDI is asynchronous serial at 125,000 bits per second (1/16 or a 2MHz crystal?), send using current loop.
Thus it should be a byte stream at the /dev level, with interpretation as MIDI data being done at main program level, rather than device driver level. That is, it should present like a serial port. And if you have a serial port that supports the funny baud rate (or something close enough), you could conceivably build a current loop to RS-232 level translator. What I don't remember is whether the DC isolation occurs in the sender or in the receiver. Probably in the receiver, so you may be stuck providing and opto-isolator, like official MIDI devices do.
