I am just starting PD now, but I am confronted at MIDI setup problem. I can't play MIDI algorithm. So I just opened up MIDI setup window, on the output devices I can't find 'AU DLS'. I am using Mac OSX. With MaxMSP, everything is OK. And when I choose 'to max 1', I can send MIDI messages from PD to Max without any problem. But, in PD window, I can't use GM MIDI. And I am afraid of not setting up MIDI part. Anybody can helps me out? Really appreciate it.
