I have a piece for saxophone orchestra which written out in the transposed keys. I needed to change the key of each part to the overall key (which is A major), so far so good. However when I look at the part for Alto sax, the key has transposed to 6 sharps (E sharp maj?) rather than 1 flat. The help suggests ticking the “Prefer enharmonic key signatures with fewer accidentals” box - which was already ticked. Unticking it makes no discernible difference. How do I change the key to 1 flat, rather than 6 sharps?
