Yes, Grim that's what I've been doing in the arrange window for many years now.
As an arranger I am also called upon to do take downs (ex. Amer. Idol, or new singers with demos but no charts, or arrangements for something that has a piano and vocal only, etc.) and then transfer all that info into Sibelius for charts/arrangements/orchestrations using the original audio to play along with the new added tracks..or do it all in Cubase if they need the audio of the arrangement and not just the charts. That usually takes me an hour to do a pop song length tune. I've gotten pretty good with that over the years. But I've never quantized any audio in those situations. No real need to.
I'd hate doing it for a 2 hour concert that's contiguous. But for a single song, no problem.
I've chuncked it down to the front part of the concert (40 min) the middle (piano duets for 30 min) and the last half with the orch returning and a choir added (20 min). I'm avoiding doing this project into single songs since there's a lot of MC and actors and singer talk between songs (like a broadway show) and I don't want to end up doing a lot of resynching in the end. 3 x is enough not to complain, ha.
But now that I'm thinking all about this over again to make things work faster, I think the kick drum will be fine.
