But then you record over audio that you actually want to hear before the recording starts. You could make a new audio track and then do what you suggest.
Well, if you just want to re-record a certain part of, say, a vocal, because the singer has difficulty getting that part right, you may want to cycle that area with pre-roll. But if you have to make a new audio track for every time that occurs, then that's not really efficient and handy.
I find that quite disturbing in an application that's called "pro". It's quite basic stuff; cycled recording with punch in.It's been broken for a while now :-(
