Thanks much, Christian (and for posting in both forums) I'll need to study this and do some experimentation. So it looks like relying on Flex, rather than Vari Speed, is the best bet. Also, by recording 'separately' I assume you're talking about dedicated tracks, as opposed to in a separate project or at the end of a project, correct? I was a little concerned that altering tempos in the middle of a timeline might cause sync issues down the line, but it would certainly be more convenient if we could keep everything in its proper chronological order. Unfortunately he's talking about as much as a 20% change in tempo, which I have very little hope of sounding acceptable.
