Thanks guys. Actually it isn't "remove all bar settings," it's "reset all bars." Close enough. I held my breath and clicked on the button and the red lines disappeared. I didn't do anything with the tempo in there -- could have, but didn't -- but now it's taking tempo changes. Okay, I knew it would be something simple, but I would have probably searched for hours before I got to that F5 menu. So thanks much!

Tell you what, this auto-interpreting of an audio file's chord progression sure is nice. In this particular instance, it got pretty close, but missed on a few chords. That's okay, though. Gave me the excuse to get in there and tweak the progression more to my liking anyway. Cuz now, it's mine!
