Hi all, hope you are all keeping well,

In BiaB for Windows 2020 I'm trying to fit a melody recorded at 130bpm to a backing track (all RealTracks) of 140bpm. I thought this would be quite straightforward, but it's proving quite tricky.

If I change the playback tempo of the piece, both the audio and the RealTracks change at the same rate, so it is still out. However, if I then save the file, the audio reverts to its original speed. This is fine if I want to fit the backing track to the the 130bpm of the audio, but not the other way around - if I get them in sync at 130bpm but then move it up to 140bpm, they will stay in sync until I save the file, at which point the audio drops back to 130bpm.

Any ideas? I've had a look at the manual but couldn't see anything on this specific point.

Thanks!

P.S. As a side-query, I've noticed that if I select the "Audio Chord Wizard", I then lose the option of "mark this point as bar 1 of the song" from the right-click menu and I can't get it back unless I exit and reload BiaB. Anyone know how to fix that, short of exiting the program?
