Long time ProTools user here, well at least I used to be before they elimated all support for the MBox and made the Win7 drivers non-compatible with it also. But it still "runs" on the old drivers on a Win7 machine, just with its typical problems. So to make a long story short - I have moved to REAPER.

But none of that answers your question. RB is not a plug-in for PT 8.0, it just runs concurrently. However, I was never able to get the D&D going between the two programs. Perhaps you will have better luck. By the way RB does D&D into REAPER.
