This is something that I come across occasionally.
I'll open a songs that I have saved (with Alt F2) and the tempo has changed.
For example, I've saved a song at around 140 BPM, but when I re-open it the tempo says 90 BPM.

All I can put it down to is, at the end of the song I rall the bars and reduce the last 4 bars by -20% (from F5)
This appears that the final tempo is what BIAB saves the song at.
Has anyone else come across this? If so, can you suggest a workaround?


Cheers,
Keith
