Hi Mitch.

the MIDI does not really work. If I specify the MIDI port with
% ./pd -midiindev 0 -midioutdev 2 using default input device number: 0 using default output device number: 2 nchan 2, flags 3, bufs 8, framesperbuf 256
Things seem to work fine. Any idea why?
Not really. I've had zero effort working on the portmidi end of things... the "extended" version simply keeps what Miller has done. MIDI configuration is one of the most difficult aspects of Pd on MacOSX--it's unpredictable and unfriendly (presumably because it inherits from portmidi)--but I have no clue how to improve it with my very limited testing resources.
However, since you've figured out what configuration works for you, I suggest adding the lines:
-midiindev 0 -midioutdev 2
...to your .pdrc file... that's exactly the sort of thing it's meant to help.
Cheers, adam
