Despite being an off-and-on user of BIAB for more than 30 years, I only just realized how important it is to set the Key of your song in the top header next to Tempo if it is not in the key of C.

If you don't, BIAB will hijack your chords and change what you hear, thinking you are playing in the key of C.

I would suggest that PGMusic quickly figures out the key of your song by the chords you start typing (not difficult at all to do this) and adjusts the Key at the top of the header to match this.

That would be the optimal solution to this problem.

If the programmers can't figure out how to do this, I would recommend that by default, when a user starts to enter their first chord(s) to a song (that's not in C) a pop-up comes up reminding them to change the Key of the song from C to their new key, unless they turn off this default acknowledgment setting.
