This program is a cover for the original Marble Machine. It was created in collaboration with Eric Hope. It uses a piezo buzzer, or you can cut an unused aux cable and then strip it, and connect the wires to your arduino (with a lot of resistance, or otherwise you, like me, will be literally blown away by the volume of it). It will have four channels in it when I complete it, one four the bass, one for the lower notes of the melody and the last one for the upper notes of the melody.
