The cue marked in green should be the in C note at the place marked in orange. The cue needs to be positioned in C, while the rest should remain in the original F. In this case, how should I enter the cue? If I input it with popovers, it comes out in F.
If I want to transpose and display it in a specific C, how should I do it? Should I adjust it again by looking at the concert instead of using popover?
You cannot do it without changing the source of the cue.
IIRC there was a discussion about this on the forum. Dorico does not support un-transposed cues in transposed layouts.
(Others may correct me if I’ve got this wrong)
I mean create a player that you hide in the score (you’ll still see it in Galley View), copy/paste the passages you need into that staff, transpose them down by a fifth, and create the cues using that staff as a source (if I understood correctly what you want to achieve)
It’s a way to transpose with the Note Tools popover (Shift+I).
dmaj to gmaj down means transpose down from D major to G major (in this case t-5 or Alt+Down arrow 4 times would do a diatonic transposition, so the 3d note would be a C sharp instead of C natural. Edit :t-5 7 div would have worked also (where 7 div means seven semi-tones) Edit #2 thanks to @asherber: t-p5 is the best way!
