If I mentioned this in past, sorry I simply do not remember. I add items to this topic when issue arises.

One of my BIG requests for BIAB was/is: "selected bar freeze"
I can understand how it can get tricky because with minor change, the rest of things PRE & POST sections can change and it might not be smooth at the end...

As a stone age alternative if "selected freeze" is not being made, I can live with "export selected bars as individual tracks". When exported they should fall in the correct section in timeline, with silence before/after. Example. You select bars somewhere in the middle and hit export selection... Exported WAVs would look something like this:

1)-silence--silence--silence-EXPORTED AUDIO DATA--silence--silence-
2)-silence--silence--silence-EXPORTED AUDIO DATA--silence--silence-
3)-silence--silence--silence-EXPORTED AUDIO DATA--silence--silence-
4)-silence--silence--silence-EXPORTED AUDIO DATA--silence--silence-
5)-silence--silence--silence-EXPORTED AUDIO DATA--silence--silence-

Not ideal at all, but very usable. Selected bar freeze would be better smile
