Hi,

You are using the correct way of enumerating sources.

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

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.

If an app creates a virtual destination, then other apps call MIDISend for that destination and the creating app receives it as input.

It would be simple enough to write a small test tool that creates a virtual source and verify that your app sees it...

Hi All

I'm getting reports from my users that "virtual" MIDI ports from other applications (such as Numerology and OSCulator) are not showing up as input devices in my app. IAC MIDI devices are showing up fine.

I use MIDIGetNumberOfSources/MIDIGetSource to enumerate the available sources.

Is there some other way of enumerating sources I should be using to see the outputs from other software? Any suggestions?

Thanks!

Ross.
