I have decided to add an English horn to the oboe part as a double. I would like the score to show that in the staff name, i.e. “Oboe & English horn” on the initial page and “Ob. & EH” subsequently instead of showing the name of the “active” instrument only. The part does it just fine, but the score does not.
I gather that the only way to actually switch from one instrument to the other is to go to galley view and start writing in the appropriate line as both parts of the double appear there. Is that correct? Once I’ve started a passage, then I can go back to Page View and continue. It’s not a problem but it took me a while to figure it out.
