Hi
The ACW is getting better and better when it comes to adding real tracks to a pre-recorded non-click track, i.e. when tempo is "free".
However, when opening an edited file from the 2019-version in 2020-version the added/edited bar lines are offset and the sometimes tedious work done in the previous version is lost.
For some files it seems to be working fine and it seems to be for songs which have the first added bar line coinciding with bar 1.
For the others not working, I have an added bar line in front of bar 1, typically for a pickup bar. I guess this is what messes things up for 2020.
I guess only PG could answer what's causing the problem with the misalignment, but obviously it has to do with a reference that is not expected. It was ok in 2019
cheers
