I have a basic GM drum beat that when I open in the score, the Hi Hat stem goes down with the Bass drum stem. I want the h/h stem to go up and the b.d stem to go down. Both notes are on the same beat. Anyone please…???
In the Drum Map Setup, set the Bass Drum as Voice 1 and HH as Voice 2 (or vice versa). Then in the Score Settings > Staff > Polyphonic select Polyphonic and set the Voice Nr 1 Stems Up and Voice Nr 2 Stems Down. In the same window, you can define, what Rests do you want to show.
See attached screenshots, please.
