>> Obviously, if they don't have the necessary RealTracks etc., they won't be able to hear the output as I hear it, but I would like to be sure that they can at least create leadsheets (transposed as necessary for their instruments).

Do earlier versions of BIAB deal elegantly with new features that weren't invented when they were released? How far back is it possible to go?

==========

Yes, the files are backwards compatible, so they will load into an older version of BB. As you mentioned, they won't have RealTracks (of course), but they would just need to change the style to one that they do have ( a MIDI one), and the files will play fine.

The chords/ leadsheets display and print out without needing to change the style - those would just load and display/print.

Have Fun!
