Is it possible to notate rhythmic tutti cues above a drums part? If there are notes in the drumpart I can’t notate cues.
Unfortunately you cannot currently add cues to a percussion kit: this is something that we plan to improve in the future.
For now you could consider giving a pitched instrument to the player with the drum kit and adding the cue in the pitched instrument; through the magic of automatic instrument changes you should find that you can get approximately what you’re looking for by hiding the instrument change labels etc.
