Hi Doug

Thanks for the response.

You are using the correct way of enumerating sources.

Are you certain that the other apps are creating virtual sources and not virtual destinations?

I am not certain but since these other apps send MIDI I assume they act as sources. Also my users are reporting that they can route MIDI from these other apps to mine using the IAC routing mechanism, it's just that they dont show up directly as sources in my app.


Now that I know that I'm on the right track at least I'll do some more tests.


If an app creates a virtual source, then it calls MIDIReceived for that source, and it appears as input to apps that have connected to that source.

So from what you say, there is no logical difference between a hardware MIDI device driver and another app which sends MIDI?


Thanks

Ross.
