Judging by posts in the last couple of days, I should be able to get the motu going with Pd 0.36 and port audio april version.
No inputs will shows in pd though. Only outputs.
Not so sure about the midi - has anyone used usb midiman box with Pd on OSX? I seem to remember reading that port audio midi on OSX is buggy.
I have had no problem with all the midi interface I have used so far (3), but finding the right port is a bit tricky.
Good Luck Alex
