Who can help me?
I have a music score with "layered" notes.
What do I have to do if I want to use only the upper notes of this score. I want to delete the lower notes?
Sounds to me like you may want to look at the "Parts" user tool.
It's not clear to me what you're asking for. Are you using the "layer with next staff" option, and want to know how to remove one of the staves? Or are you working on a single staff with chords of two or more notes, and want to know how to remove a single note from a chord without disturbing the others?
