This device is what I’ve named THE CIRCLE MACHINE. The intensity of each light in this circle is individually adjustable. At the tip of the arm there is a photo cell. This cell is a part of an electronic sound generating system, so adjusted that the more light the cell ‘sees’ the higher the pitch of the sound produced. The cell also moves around in a circle at adjustable speeds. One of the controls, above the circle of lights, changes the pitch center of the complete cycle when required. As you will notice, there are many variable functions possible. Here is a demonstration of an electronic effect possible with THE CIRCLE.MACHINE—Raymond Scott
