Daniel, I found this old post of yours talking about exactly what I want to do (back then still in development), which is change the convention from Dorico’s default (kick+snare / cymbals) to one-voice notation. But only for a section of the piece, so this shouldn’t be a global setting in this particular case.
Would that be the “elegant” way to go about it then?
Also, for future reference, is there actually a way to set up any of the other conventions globally for the project, so that it automatically puts the elements of the kit in the correct voice without having to manually change the voices later? Curious especially about the hands/feet one.
