showing different clefs in score and parts for C score

[jmus]

Can't remember if there is a way to do this.

I want the score to show in C, but some of the horn passages would need to be in bass clef. The parts would be in treble clef

If I change the clef in the score it automatically changes it in the parts as well

… I want the score to show in C …

Since you specifically mention that the score should display in Concert Pitch, I suppose that the parts should display in Transposed Pitch - right?

This work for me:
For the Horn staff, in the Instrument List, set the First Clef to Bass Clef.
For the Horn part’s {Staff Transposition}, use a custom staff style that sets the Staff Transposition to Treble Clef.

Thanks, that's great
