Click a staff to place notes. Add more instruments on the left to stack a score.
Write on a staff: click the staff you want (that instrument becomes active), pick a duration, click at a pitch. Chords: hold C and click near a note. Edit: hand cursor = grabbable — click to select, drag up/down to repitch, Shift-click to highlight several, ⌫ deletes.
Stacking: add Guitar, Bass, Piano (grand staff) and Drums on the left — they line up bar-for-bar and play together. Piano & bass default to the right clefs.
Next: guitar articulations (bend/slide), proper drum noteheads, and PDF/MusicXML export.
