Cant cut paste. I am new to doing this particular thing, but I know enough to know that you cant cut/paste. Time stretch… how? If the track is 24 bars long - how to time stretch bars 9-12 only?
Cant cut. Cutting is out. Do you know what a violin section recorded with hall ambience sounds like? Can not cut.
So I shoudl d/l a competitors product? 
I dont care about cumbersome. Even if it is, it’s probably easier to do it in Cubase, rather than d/l and install Reaper. So, Cubase does this? How? Free Warp as JSQ suggests?
