I correct the setting to what I want, resave, save as, save +, any and all combinations of the three saves, and it plays well as long as I pull it open from the recently play list. Once I close BIAB and go back a day or two later to reopen the file, I'm back to the corrupted settings.



question:
if you close BIAB, then reopen and start the song from the recent files list, are the volume and panning correct? Or does it only stay correct if you open and close the file without closing BIAB?

if it opens from the recent play list (after BIAB has been closed and reopened) and all your saved settings are there, my guess is that when you saved it the first time, you inadvertently saved it to a different location,. In other words, you could have two versions of the song.

If that's the case, When you open it from the recent play list, you are opening the edited version without explicitly seeing where it is stored. That could be why the tweaks are intact.

When you open the file from its original location, you could be getting a version that was saved before your tweaks.

To test this theory, search your hard drive for the song's file name. If you find more than one file, the one with the most recent save date is probably the version with correct panning and volume

Or not.
