Although this is easily fixed by moving the trill in Engrave mode. I was wondering if there was a native way of having the ornament placement follow the notes to the lower staff.
No, I’m afraid not: if the ornament were part of the note itself, then it would travel with the note when you move the note, but ornaments are separate items that live on a particular staff. Cut and paste will be required in this kind of situation.
I also wonder if you would have received a different result if you had actually changed the note to the lower staff (semantically) vs. simply telling it to display on the lower staff. (ie- alt+m vs. just ‘m’)
Yes, Alt-M (or Opt-M) to move the notes does indeed take everything with it, including ornaments.
That works much better in my situation. Thank You.
