I have tried importing an audio into BiaB through the Audio Chord Wizard and creating a tempo map to work with it. However, the audio isn't perfectly consistent in its tempo, so I took the time to mark the bar lines manually. I then imported a MIDI file with the melody and played it over the imported audio with the tempo map and everything seemed to be great. But when I saved the file, closed it and reopened it, BiaB was all confused and was not playing the audio in sync with the tempo map at all. Has anyone else had this issue, and is there a fix?
