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

Thanks

Thanks for your reply. I'll investigate the MIDI endpoint solution but it looks like it's going to be much more complicated!

Does anyone know if there any plan to support such MIDI routing in Logic in the future? I am surprised there is a new API (it appeared in 10.5 I think) to output MIDI data and you can't do anything with it in Logic.

With Audio Units it's possible for an audio effect to output MIDI data thanks to the kAudioUnitProperty_MIDIOutputCallbackInfo and kAudioUnitProperty_MIDIOutputCallback properties. We were able to test this with several host applications but could not find a way to test this in Logic: is there a way to route the MIDI output of a plugin to the input of another one or to the output of the MIDI interface? If it's possible, what's the procedure? Can this be done accross several tracks?

To my knowledge, no. I'm struggling with the same problem. My plan is
to create an AU that connects to my composition application via OSC and
feeds a Logic track with MIDI (either live or as a batch by inserting
regions). Can't yet see how to achieve that.


With CoreAudio/CoreMIDI getting more mature and widely used over time,
IMO its time to acknowledge that the unidirectional role model where
the "DAW track is the sole source of all MIDI" is no longer viable.


Concerning your question: You could try to create a new MIDI endpoint
for your plugin programmatically and connect to that from Logic's
environment. I doubt however that this connection is retained by the
Logic project automatically.
