[Funny, just wrote this in response to another question...maybe this should go in a manual somewhere ;-) ]
On OSX, you must open the "Audio MIDI Setup" application to get MIDI in/out of PD. Once you have done that, you can use the MIDI Settings menu in PD to route MIDI in and out from/to your various devices. Haven't tried routing MIDI from PD to Live, but I imagine that if you select the built-in OSX MIDI "IAC" router as output in PD and input in Live, you'll get something working pretty quick.

hi
Im using on my home PC win and Linux version of pd and on both systems i have "multiple midi in-out" and "alsa connect" . On my job machine (mac osx pd-extended 0.38.4)i can use just one in-out - the main one from digi002. Where are this settings and can i use something like alsa connect to connect my pd with Live + all my midi controllers on osx? thanks 2 all
