This setting allows the user to manipulate sound by placing a shadow over a sensor. The darker the sensor, the louder the loop. Each of the 16 sensors controls an individual audio loop. In addition to controlling audio, each sensor also controls the brightness of a corresponding light segment. This setup allows for more control and less feedback. With some careful selection of audio loops and some practice, one could make some pretty awesome sounds.
