This may be stupid, but here goes.
I set up a new orchestral piece and saved it with no notes input, but all the players and staves set up. I opened it today to start entering music.
I can select bars and enter enter music on some staves, but not others. --in fact, not on on most others. It’s like they are locked.
For example, I can enter notes for piccolo, timpani, and trombone; but for most other staves (horn, flutes, clarinet) I can’t select bars or get a carat.
Update:I opened anew Solo Piano piece as a test,and it worked fine.
What’s going on?
