I have struggled for quite a few days now to try and get MIDI into pd via the IAC driver... from Live, from Logic... and nothing happens.

I've created busses in the driver called Pure Data In and Pure Data Out;
I've selected the driver in Live/Logic;
I've opened Live/Logic before opening pd
I started out trying to get MIDI clock in through the <<midirealtimein>> object and when nothing happened, I checked the <<midiin>> object - still nothing.

Can anyone help out?

I'm on OSX 10.6.8

Thanks,
Brett

I'm not sure about how to go about it in Live, but in Logic there is an issue of MIDI feedback loops. Or at least there was in I used it a few years ago. See if this helps:

With Ableton, make sure that your IAC bus to Pd is set to output sync nessages. Not to be condescending but it's an easy thing to miss/forget to do.

I've found that it works just fine using the exact technique you describe, except for the sync jitter. For some reason Pd actually seems to run ahead of Live's internal clock, it's pretty odd but it works at least.
