Yup, thanks, got it on the speeding up bit. Played with it a bit the other night and noticed a few pitfalls... looks like it would be best if I record and mix at this speed (if I don't want to re-work everything) … render it to wav, and mess with the speed in a different project on that wav file, so I have the original master to go back to. I'd changed the speed, and then tried overdubbing some vocal bits and it got pretty weird on me.

Fortunately, I was working on a copy.
