>>> As I pointed out before, it doesn't do the transposition correctly

>>> I think the problem is the way the notes are stored. If you store them by MIDI note value, information is lost.

Yes, BB's tracks are MIDI information only. They don't store accidentals or other notation information.
The melodies are typically entered by people playing on a MIDI keyboard. They play in the piece, and that's it - no messing with accidentals. BB guesses at the best accidental, usually based on the current chord.

If you want a specific accidental, you can do it. Right click on the note, and force the accidental. (but not Fb Cb E# and B#)
We could improve that so that you could also make those notes on the notation in a future version.

Band-in-a-Box lacks Fb Cb E# and B# . We made the program 21 years ago, on a text only IBM-XT machine, before notation etc. As I recall, we were in 1989 running out of bits (not bytes!) in the file data format, and In a do-over, we definitely would have included those keys.

>> May I suggest that someone call Eastman and have them verify what I'm saying?
There are some areas where a musically trained person would be able to resolve a
lot of these issues for you that a programmer wouldn't spot.

I went to Berklee, so wouldn't be calling Eastman.

Have Fun!
