Respelling the key of transposing instruments

[Stan7]

Hi there! I have to re-arrange a musical theatre score. The specific song I’m working on is written in E major. The Bb trumpet is written in F# major, but the original score notated in in Gb major. Is there a way to make Dorico respell the key of transposing instruments? Preferably only a specific instrument, since some other transposing instruments are notated in F# major.

Hi!

In Setup Mode, right click the trumpet layout and choose “Clef & Transposition Overrides”

In the dialog, set “Written middle C sounds as” to A#3 (instead of Bb3), then click OK.
