If the only port you have is for output only, trying for input seems futile perhaps?

I'm trying to open a midi port to receive incoming midi commands and am completely stuck (after a week of trying everything I can think of). I've confirmed that the MIDIPlugin is loaded. I've tried on both Windows XP and MacOS. The only port I have available is this:
MIDI Ports: 0: QuickTime MIDI (out)
Everything I have tried to create a new one has failed in the midi open primitive.
I suspect I'm just being dumb and there is an obvious incantation (hope so anyway).
Thanks so much for any advice you can provide.

Agreed...that's why I've been trying to create a new one. For what it's worth. I can't output on the existing port either since it seems bound to the internal Mac sound generator. Oh well.
I'm on the verge of deciding this is impossible (is it really true that no one has made this work?). If so I'll try to build a primitive to access the portMidi open source code. I would REALLY like to avoid this path but no one seems to know how to do this seemingly simple thing.

You might look at the macintosh C code in
http://squeakvm.org/cgi-bin/viewcvs.cgi/trunk/platforms/Mac%20OS/plugins/MID...
I think MIDI ports are tied to devices, if the device doesn't exist you can't create out of air...

also ask Craig Latta, he uses a Mac and has his MIDI ports working.
