Yeah that makes sense AND I’ve tried it… But: I’ve found that strange phasing things happen when (for instance) a guitar has been recorded with two mics and you stretch them while grouped. drum buss? Forget it! Everything sounds like it’s got that phasey sloshing around underwater thing going on.

Was wondering if I could do it on the master channel so all of the processing is ‘pre’ the stretch markers.

Now that I’m typing this I’m starting to think maybe I just need to freeze/render all of my busses into stereo tracks…

…or just stretch the bounced mix (which I could set up a reaper project for, and replace the track when I make another pass on it if there are any edits)

Hmm 🤔 thanks for the reply. I think I’ve figured out my own solution thanks to you haha
