[Rwp] Time stretching

If you nudge one item down and do your stuff while ripple is turned on,
and nudge it back up it seems to cross-fade the items and shorten your 
over-lap, but if you leave it separated on different tracks, then it 
plays the way you stretched it.

So you can do what you want, might mean moving the furniture around a 
bit manually with reaper's nifty push and shove and nudge and growing 
edges and such but a little ear work should do it just fine.
I'm now starting to experiment with stretch markers,
and locking tempo and such, but for the longest time I've done reaper 
rubber-banding with just feeling it and by ear,
and that has worked well for me, I have this client who jumps quarter 
notes and 8th notes like a frog in a pond, and I just pat my foot, and 
line him up I usually don't have to split tracks, but sometimes I have 
to take out whole chunks,
and then nudge the edges together nicely, and reaper usually let's me 
get it done with not too muchbother.

Sometimes I mess it up and have to take another swing at it,
but if I cut my wood right usually the meld is pretty seamless.

YOu can use your shift and top row number keys to slow down and pitch 
things the way you like.
