Punch the numbers into a telephone dial pad in a phone booth outside the bar, and a concealed door swings open to reveal a classic cocktail joint that swaggers with the decadence of a 1920s Chicago speakeasy.
The bottom-left 4 x 4 pads represent drum sounds (touch the slider to scroll up and down through even more sounds), while the bottom-right quarter of the grid serves as a clip-length control (press and hold the first pad, tap the fourth for a four-bar loop, etc.).
