The Harp app is another laser light and musical instrument. In this app, the input is created when your hands block beams of light.
A camera input is required to use the Harp app. To set it up, turn on your LaserCube. In the Harp app, toggle the Preview switch to ON. Point your webcam at the dots projected by your LaserCube. If necessary, adjust the threshold slider until the dots seen by your webcam are distinctly seen in the preview window. Toggle “Enable Laserharp” to ON.
