Hi, I think I had the same problem - MIDI tracks in Pro Tools prevented the file from playing. When I pressed play on the transport bar, stop would press itself immediately.

I deleted the files that you mentioned, BUT I still can't get my MIDI devices to play through Pro Tools (nor through Noteability Pro). Both of my MIDIsport devices seem to be getting no input from the computer: the new 2X2 that I am trying to test, and the 1X1 that has worked for a couple of years on another (PC) system.

I am wondering if there is a conflict with the MBox that will not allow me to use these devices on the same system. Do I need to get one of the MIDI interfaces approved for use with MBox?

I am running Tiger on an iMac G5 (brand new)

Thanks!
