Currently, I have a “player” playing two violins, and another “player” playing another violin. These appear as “Violin I” and “Violin III,” and “Violin II,” respectively (presumably because I added another violin to the first player after I created the second player).
How do I change the names of the instruments to something more descriptive of my needs/intentions?
If you expand the player’s card in the Players panel, you’ll see little labels representing each instrument. Hover over them and a little chevron > will appear; click and a context menu will appear from which you can choose Edit Names.
