I have a project where the procedure John describes at 6:08 does not work.Jazz Drums, Percussion Labelling and Controlling Master Frames | Discover Dorico with John Barron - YouTube I can open a new big band score, and it works fine, so this misbehavior must be a side effect of something else I have set in my project.
I create the slash instrument in setup mode. I switch to write mode and start note input in the drum kit part. Screen looks just like John’s, and my test score. It is showing Sl. for note input on the middle line of the 5 line staff as it should. I enter Y, and instead of a slash I get a standard notehead. Plays back as wood block, just as John’s did.
I’ve checked engrave->notehead sets->slashes. No difference between test and actual project. engrave->engraving options->rhythmic slashes is set to oversized.
What else should I check?
