I have a piece for two voices with optional instruments. One of the optional instruments is flute, but I would also like to indicate that it could also be played by violin. How can I put both those names in the instrument name, i.e., Flute / Violin for the full name, and Fl / Vln for the abbreviated names. Thanks!
You can edit instrument names in Setup…
Open the Player tab to show the instrument and click the … (circled) to open the sub-menu. Then select Edit Names
