Is it possible to have both Audio and Midi Output for Audio Units?

We compile a project on Mac that has Audio and Midi output.
In VST3 it works fine, but the AU format doesn’t have Midi Output.

So we are wondering if AU can output Midi … (without being classified as Midi FX generators)


I don’t think Audio Units supports that. An effect type outputs audio, and a music effect type outputs audio but accepts midi commands as input, and a music device type outputs MIDI but not audio. I just don’t see any Audio Unit type that supports outputting both. See this page:
