I have a score that started misbehaving today. My percussion staff started playing pitched notes (one example is Kick Drum 1 plays back as a soprano cornet, among others). I tried reassigning the Noteperformer playback template. In the NP mixer, I get Timpani and Orchestral Percussion. The pitched notes are coming from Timpani. I can assign a new instrument to Timpani (but not unpitched percussion). I cannot assign a new instrument to Orchestral Percussion, only the option to delete it. Any ideas? Thanks in advance.
UPDATE: I’m not sure what caused this problem, but I solved the problem. I simply had to create a new player, and assigned “drum kit (full)” instrument. I copied the music from original drum it part to the new one, deleted the old player and NotePerformer assigned this staff to Drum Set (sticks).
