Phil,

When I lay out a song in BB, I initially like to have it all on one screen in order to see the song in its entirety. As such, repeats, 1st/2nd endings, tags, and choruses all provide a quick overview so I know what goes where- soloists, changes, etc. This way I don't have to scroll up and down 3 or 4 screens.

It looks good, but playback can be problematic:

The repeats repeat but don't play back properly instrument-wise. At least that is my experience and why I invoke repeats only if the actual notation is required.

I finally got a grip on 1st/2nd endings and tags, but any changes made after they've been set up create additional difficulties.
Other users may not run into these problems.

So unless the tune is very basic, I usually end up unfolding it in the end.
BB can be frustrating at times, but for me it is indispensable.
