I have put a 25 year old wind quintet into Dorico - it’s looking (and now) sounds good but in the absence of cues in parts I thought I would make cue lines for each instrument’s part. How would this be best achieved? A guess it will involve layouts in some way or other?
I guess you could choose to add another of your existing players to your part layouts, and set the added instrument to use a smaller staff size (select a note in the extra instrument, then right-click and choose a smaller percentage staff size from the Staff Size menu).
