[PD] Mac OS X MIDI input troubles

Hello all,

Hoping that others who are running on Mac OS X, using MIDI, could tell 
me how to get MIDI input to PD? All the other applications that I have 
(even some of the source code examples I compiled) see my MIDI interface 
(an emagic MT4 [2 in, 4 out]), and I am able to select what ports I want 
to use for a particular MIDI track (or thread), both in and out.

I am able to get MIDI output from PD into other programs, so that does 
not really seem to be an issue. It does appear to be sending all 
Actually, I have to do this using a "loopback", patching one of the 
output ports on the MT4 to one of the inputs. (Is there such a thing as 
an internal MIDI buss? Or can PD be set up as a Virtual Source?)

Also, what is the relationship between the commandline switches (and the 
values passed) to how how CoreMIDI works?

Is anyone successfully getting MIDI input and outout, on selectable ports?
