Hey Jim, well for me, it isn't so much filling out the chord sheet as it is preparing the audio file so that it will be interpreted properly -- or at least closely. To get close with the ACW, I had to first establish the correct tempo, and then I had to prepare the audio file so that the audio file's chord progression began at Bar 1, beat 1. Then I had to make sure that the tempo matched in BiaB, and just for good measure, I also set the key to the correct key in BiaB. It was then, and only then, that I imported the file and then ran ACW.

Only after I'd run ACW did I dismiss it (the way I found to do this, which may not be the most elegant, was to click on Audio>Audio Edit Window twice), and then hit F5 to get rid of the red underlines. I also had to click on the little rectangle in the gray "Drop" box to restore the look of BiaB. It was only at this point that I was even prepared to select a style to try out the progression that had been loaded. So for me, the chord sheet is way in the back of the to-do list.

But, I dunno, maybe it's all in the way you look at it. Maybe what I just described was filling out the chord sheet?
