The ongoing work on percussion is coming along quite promisingly. The allocation of notes to voices on a drum kit staff will be dynamic, so you can choose between the various conventions in use (we’re aware of at least three: kick and snare in the down-stem voice, with hi-hats/cymbals in the up-stem voice; kick in the down-stem voice and snare/hi-hats/cymbals in the up-stem voice; and everything in a single up-stem voice), and the music will be renotated automatically to match. You won’t have to worry about voices at all during percussion input: just input the note at the appropriate staff position and Dorico will do the rest.
