Build 1123 had been just released, the points I was referring to were these ones:

Added: Stems, now has a button "Use Existing Audio Track" which sets the stem splitter to use the Audio Track and set various options
Added: Process to make Stems, use ACW for TempoMap and Chords, and then Equalize the tempos to one tempo has been improved with several additions
1. When bar 1 line moves, the stems all move as well in sync
2. When equalize tempos is chosen, the stems all get equalize tempos too so they stay in sync
3. Style changes don't change the tempo if audio track or stems or tempo changes are in place

These new features are really useful, make the whole process way simpler and intuitive, and work very well.


Latest BIAB version, latest build.
