With the left-hand scanner, you can scan any coordinate to instantly create a rhythm. Scan a new coordinate, and the current rhythm fades into a new one.
The right-hand scanner controls the melody. Every coordinate contains both a rhythm and a melody, but you first need to scan a coordinate to unlock it. Then lift the scanner, hold the black button, and tilt it.
As you move, different angles trigger different notes, creating a flowing melody while the synthesizer lights up in response.
