Thanks Vas, I'll try that.
ETA: Works perfectly as described on 10.10.2. Beautiful
ETA2: I'll add the MESS command line should be something like:
./mess64 snes miraclep -ctrl1 miracle_piano -midiout "IAC Driver Bus 1"
If it starts playing La Bamba you're good to go. If all you hear is the annoying SNES metronome, you have a problem.
