There is no real way for an AU to control an external synth - audio
units are for generating audio (or processing)...
FWIW, What he's asking for is probably my most requested feature.
AudioUnits are lovely, but old geezers like me still have a lot of
hardware synthesizers too. I don't really give a fig whether a synth
is real or virtual, I want all the synths in one menu and I want to
just pick one and use it on a given mixer channel.
The 'puter already knows about all the midi devices courtesy of Audio
Midi Setup. But AMS only lets you specify MIDI connections. If it
also captured the audio connections between these and the channels of
the various audio interfaces, then you could write something with the
same external interface as a MusicDevice, but instead of generating
audio, its audio output would be "generated" by simply echoing the
synth's audio inputs on its output bus. Furthermore, sending it MIDI
would just send the commands to the appropriate MIDI bus/channel where
the device lives.
In fact, I just finished implementing this although I did it at the
level of my ObjectiveC wrapper for AudioUnits and AUGraph rather than
dive into making it a "proper" AU.

So, in a broader context, what is it you want to do?

Hi,
I want to program a AU to control an external synthesizer via MIDI.
I started reading the Audio Unit Programming Guide, and planned to
go through the Core Audio Overview, but I suppose I will only need
a very small fraction of it. Is there anyone who could tell me
which parts are really needed for controlling MIDI?
best regards
Pascal
