I think this is not possible yet, but would it be possible to implement this in future versions?
I have globally selected that a drum kit just uses one voice (so the cymbals and drums are written together). However, when I have a bar where only drums are used, it looks a little bit odd if all the stems are facing up. If I could insert a percussion voicing change (similiar to the insert note spacing change) so that Dorico uses the stem direction as defined for each instrument in the instrument set-up, I wouldn’t have to start messing around manually with the stems.
Or maybe an option like “end voice after bar” is possible? So Dorico simply ends the cymbal voice and then places the stems of the drums voice naturally (everything below middle B down, everything else up)?
