Hi Foks.
One of the biggest drawbacks for me in BIAB is slow generation times...
With editing minor things there is always a looong regeneration gaps. While sitting, lets say for 2 hours, about 30 minutes is burned to "re-generation" sweat time.

And another thing. I noticed this long ago. Depending on bars count, the musical variation of real tracks changes. Meaning, if you add or subtract bars in other places than the one in focus, you might lose the desired phrasing of RealTrack, which you were happy with prior adding/removing bars at other places.

I wrote about this request some time ago, so this is sort of a roundup of things. Request is to freeze/unfreeze bars that you are "happy with" and only re-generate bars that you are working with, not touching the rest of the stuff. In theory it should save a lot of time, because you are only regenerating small part of composition. And by freezing parts of the song, you do not have to worry that some musical things will wonder away.

Thank you.
