I just tested the MIDI functionality out with my SX600 using the installation from the Apple App Store, and it all worked without an issue. I could link a registration and button, then I could load the song by pressing that button, or by loading the song the SX600 would switch to that registration + button. So it all appears to be working as far as I can tell. I did this test with a USB cable. 

If you bring up the MIDI listen dialog and press the button with the given registration, what message(s) do you see? Do you get a message that matches exactly the message saved by the linking command? I want to see if we can find anything that is off.

Thanks,
Mike
