I've been using the example from the source code CH12_MIDIToAUSamplerIOS from the book "Learning Core Audio" and can't seem to get the iOS device to recognise my midi keyboard.
The app runs fine, but I hear no sounds when I press the keys on the midi keyboard.
The midi keyboard doesn't seem to trigger the callbacks in the code (no log statements).
There doesn't seem to be any errors trigger, I see that it detected one midi source and proceeded to use that for the app.
I get this log output...

Could someone help shine a light on this? Am I doing it wrong somehow?
Thanks in advance.
