One other thing to add. PT is fussy about the order of things. So for any Rewire application to work, you first open Pro Tools and your session, and THEN load the Rewire app you want to use...Reaper in your case.



The same is true when shutting down. FIRST save any set up in Reaper (or whatever Rewire app you're using), and close it. THEN close Pro Tools. If you try to close PT with a Rewire app still running, you'll get an alert window telling you that a Rewire app is running and it might freeze the system. So be sure you do things in the right order.
