Andy,

Two quick questions (okay, a question and a thought rather). First, 
won't the SMM mess with the pitch when it resyncs the loop, or does it 
have a true time-stretch function implemented?

Second, I think I'm with you that it may be easier to use something 
other than an expression pedal for this. I was thinking you might have 
more success using something like the crossfader on a DJ console. Or 
perhaps any other slider with a center detent. Tap tempo is probably a 
good option too.

But I'd agree that this is not likely to be easy. Even though DJ's 
frequently match tempos, they're usually matching beats, not pitch (and 
they're doing it with headphones listening to both tracks 
simultaneously; not estimating and stop/starting new tracks).
