Anyone? I tried this in AUlab as well with similar behavior (inserts just fine as audio effect, but not as an input to an instrument track).
If I change the audio unit type to an instrument, I can confirm that my MIDI handler is getting called (via NSLog()). Of course, it doesn't process audio.
Should I file a bug report?
I try also to use MIDI and audio inside a AudioUnit v3.
The doc says that only 'aumu' and 'aufx' are available, I tried 'aumf' but without success for instance. The validation of a 'aumu' in Logic works, but the plug does not produce any sound.
In the case of IAA, I did a synth wich uses the microphone (the vocoder VoxUnit). It works fine, but the audio input was the microphone of the iPad . I'd like something like a MIDI effect for AU3.
I hope that AU3 will authorize MIDI and Audio Input soon.
I'm checking in on this some months later (Nov 2019), and it still seems Logic won't instantiate v3 aumf audio units.
Any info would be appreciated.
