So this is a bit of a strange problem.
First: I’m inputting meterless music, but I still use some bar lines, mostly because there doesn’t seem to be an option to treat new systems like bars for the purposes of accidentals (e.g., if I wrote an F# in the first system and the entire piece was one continuous bar, and an F# showed up in the 12th system again, Dorico wouldn’t mark it sharp because it’s the same measure). If there’s a way around this, please let me know. I explored the accidental options and didn’t see anything that would help there, but it’s entirely possible I missed something.
My current issue:
Early on, I have a whole note where I meant to put a half note. I can’t figure out any way to change it that doesn’t either leave an extra half note rest somewhere, or shift all the music that follows back a half note (ignoring bar lines). You’d think that with meterless music it wouldn’t matter that the music shifts back, but if I already have bar lines in place then I have to delete all the bar lines and redo them. The main issue is that I didn’t notice the error until after I had finished the music entry and moved to the engraving stage, so to change that one note I’d have to redo most of the system breaks and bar lines.
Thanks for any suggestions.
