Attached are the BIAB track view with the main audio file and all the stems the audio file has been time mapped via ACW and and then stem separated
They all play in sync.

The cursor playing the main audio is on a vocal top, and when "solo" the vocal stem below it is playing the same vocal at the same time, but the vocal top in the audio stem is not there it is far later.
it seems that the time map has been applied to both the master audio and the stem tracks ok but that the visual representation of the stems have not being adjusted to reflect that.

Also attached is the same files exported from BIAB (drag/drop) and into SP, and there they are all lined up in sync (i have not adjusted the time line for the bars) i.e. the same as they are played in BIAB.

(I probably don't know what I am doing, and it does not matter since it seems to work, only problem is that one can not follow along with the stem tracks).
