Doing it yourself is no big deal either. The Mac's serial ports are easily converted into midi ports with a few dollars of hardware. This "hardware" is just the glue to go to/from midi's current loop to/from the Mac's rs422-like levels. You can jam in an external clock at multiples of the 31.25k baud rate and tell the Mac to clock on that. CAVEAT: 31.23k baud could mean a char every 320uS; so interrupts are your friend!
