hmm... Actually, I'm wondering whether this has something to do with the fact that virtual outputs, which are represented as sources (not destinations), need to use MIDIReceived instead of MIDISend? I should mention that this is for playback from a MusicSequence/MusicPlayer, so it's MusicPlayerStart that outputs nothing when using my virtual ports, but works correctly when using the IAC bus.

So is there some special way of dealing with MusicPlayerStart when using virtual outputs?
I'm using the same call to MusicSequenceSetMIDIEndpoint in both cases.

I'm setting up 4 virtual endpoints for my app - at this point these are just sources, so they're for output to other apps. I'm using the PYMIDI framework to simplify things, and they ports appear to initialize correctly - no errors during init, and the ports are visible to other apps. However, they won't send any midi data. If I switch the assignment to the IAC Bus, midi is sent as expected, so it's something to do with the endpoints I'm creating.
I contacted Pete Yandell (author of PYMIDI) about it, and he couldn't see any problems in my code. So I'm wondering whether anyone else has had virtual endpoint problems in 10.5.5, or if anyone has experienced something like this and found a solution?


Thanks,
