Is there such a thing in Band in a Box? I use BIAB to make lead sheets and like to keep them to one page/screen if I can and still make it readible.
I searched the Help for Dal Segno but it wasn't listed. When I use a repeats, I usually add a tag ending and use Song Settings to jump to the tag ending at the correct point. You can right-click on a cell in the Chord Sheet and choose 'Repeats/Codas/1st-2nd endings', which gives the display shown in the 2nd image below.
The Help shows this:
It isn’t important if you (or we) call it a Coda or a tag, the important point is that Band-in-a-Box supports both a coda that occurs every chorus, and one that occurs only on the very last chorus. When we simply refer to a "coda" we are referring to an "every-chorus" coda, and when we refer to a "tag" we are talking about the "last-chorus-only" coda.
You can enter a "Tag" (i.e. Last chorus only Coda), by selecting Repeats/Codas/1st- 2nd Endings from the right-click menu on the chord sheet and selecting [Tag Ending…] button.
You enter a normal "Coda" (i.e., every chorus Coda) by a right-click on the Chord Sheet, then Repeats/Codas/1st-2nd Endings, and then clicking on the required type of DS/DC al Coda.
