The song screen is divided into nine zones. Each zone can run different actions for a tap, a double tap, and a long press. Open this screen with Edit Touch Zones.
The zones are:
Each cell lists Single Tap, Double Tap, and Long Press, and the actions assigned to each. Tap a cell to edit that zone. The dialog is titled with the zone name.
Inside the dialog, each gesture shows Gesture and Actions. Tap a gesture to edit its action list. Save Zone keeps the three gestures. Cancel closes the dialog without saving.
