You are always welcome. I’ve used BIAB for over thirty years. There are indeed a few secret codes and I’ve assumed that the changes were not made because of early design limitations that, if changed, would affect backward compatibility.

I was a comp. sci. prof. when I bought BIAB. In the early 1990s, disk storage space was still at a premium and dictated some design choices that came to bite us. The two-digit year was the big one, leading to us revising programs when we realized we were headed toward the Y2K problem.

The BIAB prominent limitation of a song not exceeding 255 measures is the best example. Using binary numbers, you can express integers up to 255 in two character spaces. Despite all the other incredible advances made, that was never corrected.

Next, my friend user AudioTrack can explain the audible count-in. 😎
