This is a strange piece, probably the strangest ever built at ARP. It consists of a single VCO, but with organ-style divide down and wave shaping circuitry. The divider only makes the same noteas the VCO is sounding. No intervals. Thus, whatever voltage you use to make the VCO make a pitch, you get that pitch (2'), and the next three octaves down (4', 8', 16'), all available at the same time, like an organ. Furthermore, there are four waveforms available: Sawtooth, Square, Pulse, and PWM, and these are available at the same time, too. Moreover, when you turn on the sawtooth and square waves and the 2' and 8' octaves all at the same time, you really do get a 2' saw, a 2' square, an 8' saw, and an 8' square, all at once! They're all phase-locked to each other because of the dividers, but if you beat them against the other VCOs in your synthesizer, it can sound really fat.
