How to keep instruments from showing in a score?

I’ve scored a brass quintet with the trumpet parts in C; but I’m publishing it with both C and Bb parts.

Right now, the score shows all four parts, but I only want to show the C parts. How do I produce a score that does that?

I’ve looked through the Help pages, and I found one that says I can do it using Frames and Players; it just doesn’t tell me how.

Thanks much.

You create separate layouts, one that includes only the C Trumpet, and another that contains only the Bb version.

(Do this in addition to keeping the full score–containing both versions of the Trumpet part–just to make sure you do not erase the music for either instrument by accident.)

Thanks, Derek; I’ll give it a shot.
