I’m using two arbitrary instruments to create an ‘electronics’ part - one pitched and one unpitched instrument. I’d like changes between them to be seamless, so not include the ‘To…’ text notes (as discussed elsewhere in another thread).
Other usage case in relation to percussion would be two instruments where, as here, the staff styles made it clear which of the instruments was required (e.g. pitched vs unpitched).
Finally, in the attached, where has the quaver rest gone to in Page View?
