The Dorico document describing the addition of extra staves says that they will be “starting at the earliest rhythmic position you selected and lasting until the end of the flow”. I want the extra staff for my piano part, but not all the way through (present and absent several times). I have been avoiding flows completely till now - am I stuck?
In SE, what you could do is have another instrument held by the piano player, and add notes to that instrument just where needed. You can hide empty staves to prevent it appearing elsewhere.
The instrument could be held by another player, which you then include in the piano part layout along with the piano.
In Dorico, there’s a concept of “players”: a representation of the humans that physically use instruments to make sounds. Just like a flautist might swap to their piccolo for some passages, similarly in Dorico the “single” type of player can “hold” multiple instruments.
If you input flute notes on the Flute instrument staff, and piccolo notes on the Piccolo instrument staff, then Dorico will handle the instrument change for you and use all the right sounds. Neat, right?!
I appreciate the detailed response, thanks! But, what would be the visual and functional difference if the flute and piccolo were just two instruments in the score and not part of the same “player”?
If Flute and Picc were two different Players joined in one layout, one would have more flexibility positioning the Picc above the Flutes and the second/third Flute Player below Flute 1, but one would also have to handle the switch-off and accompanying system breaks manually wherever they occur.
It is very common to have an instrumental part with one staff, with “switching” instructions between two instruments.
If you make the two instruments as separate Players, then they would have to be on two staves continuously; and you wouldn’t get the instructions thrown in for free.
