Hello, I have followed the instructions on how to change a key signature in the middle of a piece, and it’s not working. The piece begins in G major, and I wish to change it to A major at this bar (see attachment). I click on the rest at the beginning of the bar (and or a note), then Shift + k, add an upper case A, but then all it does is add a flat at F sharp. I’ve tried 20 variations on this, but nothing changes the key to A major. Is there a better method than the one described on the website?
I should add that I imported the Music XML out of Cubase. Strangely, Dorico seems to play the notes at the right pitches, but without displaying the key signatures.
