I’m transcribing a work for English horn, winds, and double bass. The woodwind and brass families all group as expected, with brackets and braces. However, the English horn (which, as a solo instrument, is not part of the woodwind group), and the double bass both appear as single staves without braces or brackets. I tried making each of the two single staves into its own group, but that didn’t give them brackets or braces.
Is there a way to give each of those staves its own brace or bracket yet?
