This device is not letting Groove Bank save. You can still use it, but anything you enter will be gone when you close the page.
The volume is turned all the way down, so you will not hear the drums. Turn it up with the Volume slider on the Practice screen.
Tap a step once for a hit, twice for an accent, again to clear it. Drag the grid sideways to reach the later bars. Tap a drum’s name to mute it.
Review a pattern by name, try to play it, then hear it and reveal the grid.
Car mode
Build a list, and Groove Bank speaks each part, counts you in, and plays it while you keep both hands on the wheel.
