Support kAudioUnitProperty_MIDIOutputCallback #12

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
Seems there is a way for plug-ins to send MIDI to hosts after all, but which 
hosts supports this? Does anyone know?

Don't know which AU hosts support it, but would like it as a feature. Poly-Ana 
outputs MIDI from its keyboard and pitch/mod wheels, so you can control other 
plug-ins from its interface, if you'd like. And I'd also like to be able to do 
things like pitch->MIDI converters someday too as well as MIDI processors. 
(Does AU have a separate format for MIDI processors? In VST 2.4, MIDI 
processors are created simply by making an instrument that creates a MIDI 
output as well as taking an input.)

Haha. Just found this quote by Bill Stewart (who I understand is responsible 
for Core Audio), concerning the lack of support for this property in Logic.

Please file a bug report for Logic - it helps to add your voice to request this 
feature

Thanks

So, not supported in any known host. Great. Not sure if I should keep this 
issue open at all. I'll start with downgrading it to low priority.

I got this working using virtual MIDI port.  Tested in Logic 9.  The trick is 
to delay creating your virtual port until the process call otherwise it won't 
show up.
