Thanks. I've never used Smart Tempo before. Tried a few apporaches without success. The following is what I did and what what resulted:
I went to File > Project Settings and selected Adapt. That didn't change anything. Closed project without saving.
Then, I selected to AUTO and changed the project tempo to 121 (while soloing the percussion tracks, mentioning that in case it matters). The metronome and percussion lined up, but suddenly, a number of tracks were off, both Midi and otherwise. There are a lot of tracks in this project, so trying to review and line up every track seems time consuming if there is a better option. I saved this an a separate project in case I need to go back and edit.
I then opened the original project and while almost everything was as it was before (inc. song in 121BMP project in 1, now two of the midi tracks were no longer in sync. This seems like buggy behaviour to me. I checked project settings and smart tempo was not on. I turned it on to adapt and the problem persisted. In a sense, it's not a huge deal in that I was planning on rerecording those tracks anyway but it's still disconcerting. Could this be a 10.7.1 Issue?
Ayhow, not sure how to proceed. Any help or viewpoints welcome.
