Thanks for the reply. I guess I will transfer my application code to
the AU!
Thanks for the great info.

The AU 2.0 spec does not specifically support sending MIDI from an
AudioUnit. Apple have previosly stated here that the additions to
Panther will allow you to create streams of MIDI data that operate
like streams of audio data. Pretty cool! For 10.2 support, you will be
able to install QuickTime 6.4 on 10.2 and have access to all the new
CoreAudio APIs. (Am I right about this?)
In the meantime, if you need to send MIDI from an AU, there is nothing
stopping you from making standard CoreMIDI calls directly from your
AU. You can create an endpoint and connect it to an interface, and so
on.
Actually, for what you are talking about, it seems likely that even in
10.3 you would still want to work with CoreMIDI directly. The MIDI
data streams are more for allowing users to route MIDI output from an
AU as they would audio.

Is it possible for an AU to send MIDI to an external device? I
looked at AUMidiBase and see several calls to handle incoming data
but wasn't sure if it is possible to send data. I would like to try
to build an AU that is a midi controller for an external synth.
