Alright I've been at this for a bit and still can't seem to get BIAB to do what I'm looking for. Resetting to factory settings had no effect. I've been trying Matt's suggestions, first of all I'm not exactly sure how to fix the ending bar of this song. The final bar is the Fmaj7 at 131, when I set the end to 131 it adds a greyed-out bar with an extra Fmaj7 at 132 for some reason? Then I hit backspace on the chord at 132 to get rid of it but as soon as I generate the track bar 132 is back and added to its own line, why does the program want to keep adding this extra bar? I also can't seem to delete the unused bars at 132-255 for whatever reason and they just stay there greyed-out. I've also tried every possible combination of hold/shot with and without including it in the drum part and the drum part still freaks out when it gets to that section. It would be nice, if possible, to get the drum part to accent that push, the way that a real drummer would if playing this tune, however, I would settle for just having the bass push those chords while the drums just continue to play time without any accented push but for some reason this doesn't happen when I hit 'except drums' in the chord settings menu. Worst case scenario I'll just have to not include the pushes at all for the outro but it'd be a nice touch (this track is for my grad school auditions for anyone curious). I'll look into how freezing tracks work next and try that.

musocity's approach sounds like it would work well for me as I have some experience editing audio in pro tools so I could just hack away at the actual audio region to get what I want. My only question is how do I export the wav file of the source drum file at my selected tempo?

Thanks for the help/patience with answering what are probably pretty obvious questions, sometimes searching the forum for a specific solution to what I'm trying to accomplish feels like trying to find the needle in the haystack crazy
