Wrong key signature
I have a piece of music I imported using the abc plugin. It is fine, except it has a D key signature when it is clearly written in C. I tried inserting a natural by the Cs that occur, but it won't let me, but what I really want to do is change the signature without changing the notes. That is to say I don't want the program to think I want to transpose the piece!
I have entered it into my library of tunes as "Lass o'Dallogill Wrong Sig" if anyone cares to look.
