Peter says using a new blank track does fix the generating issue with tempo changes.
I found selecting the top selection (in dealing with the first bar adjustment right after 'send to RB' is envoked) has cures some weird issues I had during testing.
I was also told by Jeff Y (who writes RB) that I may need to use Track - Consolidate audio region.

As for Stratcat32's problem, I never use that method; I always open the song in RB first, then go to ACW and use the option to run the song thru the ACW instead of opening a new file.
Maybe a slight change in workflow will solve the issue for you for now.


I do not work here, but the benefits are still awesome
