I am writing an AU Instrument on top of our existing MIDI synthesizer. I want to
just pass it MIDI events and harvest mixed audio out the back. I will handle all
the voice allocation in my code.
I looked at the SinSynth example from the CoreAudio SDK. But it just implements
note synthesis and lets CoreAudio do the voice allocation. That won't work.
I have looked at the AU docs and it really isn't very clear how to do this. I
implemented this using VST and it was trivial. A few questions:
1) Should I extend MusicDeviceBase or AUMIDIBase classes?
2) In SinSynth, the Render method only does one note at a time. Should I
override a Render() method or the AUKernelBase Process() method?
3) Are there any AU instrument example programs that handle their own MIDI events?
Thanks,
Phil Burk
