I have imported a MusicXML file and the instrument names remain full on systems after the first one. Yet for projects I create in Dorico subsequent staves have the abbreviations I would expect.
How can I change the instrument names for systems after the first system in my imported file?
First, check on the Staves and Systems page of Layout Options that the option for staff labels after the first system is set to show abbreviated names. If it’s set correctly, then you probably need to edit the instrument names for the instruments held by your players. In Setup mode, expand the card for each player, so that you can see the instrument(s) they are holding. Hover over the instrument to see the little chevron > that shows a menu is available, and click to show the menu, then choose Edit Names, and edit the short name to your taste.
