I love to work with cues, especially the way Dorico handles them, but I think there are still a lot of improvements to make.
First of all, we need to talk about the use of cues.
While in concert band music, usualy cues are used to play notes of a missing instrument (so the conductor should see the cues, to know which instrument is gonna play a passage), in symphonic scores, cues help to find your entry in the music, which is something the conductor does not need to see.
So while you want to see the cues for substitues (or at least the text saying “cues Oboe 2” and therefor set the option for cues in the score to being visible, you still want your cues for the entries of the musicians, which you then have to hide manually. For a little piece of 10 minutes this already takes forever, especially with Dorico having huge lag spikes when editing cues.
What could help?
For example a little option, to decide if the cue is gonna be hidden already when creating it, for example by opening the cue window with a second shortcut like “Shift+Alt+U”
Basically you could create a second form of cues like this, which can be customized individually.
This would als help to solve another problem:
While cues for entries don’t need to be in the right oktave and changing it is often helpfull to be more readable, in the case of instrument substitutes it’s a problem. (and normally, as they are chosen bei the composer, the fit into the range of the instrument, so clef-changes or octave shifts are always wrong.)
What I would consider a bug, are bass clef cues in treble clef parts with ninth-transposition (Tenor Saxophone, Euphonium, Bass Clarinet). Dorico in this case always choses the write the cue 8vb, so sometimes it is not readable at all.
(and yes, I am aware of the possibility to change all this manually throughout the score)
Last thing is a performance problem happening with larger scores:
2. When I want to change the length of a cue, I can grab the end of the line and pull it across the staff. But as Dorico immedeatly tries to update, even on my fast machine adding more then one note to the cue at once is sometimes not possible, as you have to wait 3 seconds after each bit.
You might consider to update the part only after the user let’s got the “line”, or even update the cue itself only after. (Although this should be an option, as seeing the cue while altering it is great!)
If you have questions on details or need examples, feel free to ask for it.
