we build analog musical synthesizers in the tradition of bob moog, who is one of the pioneers of electronic music. my name is cyril lance, and i'm a design engineer here. let's take a little tour of the factory. all right, here we are out on the production floor. this is where we build all our synthesizers and musical equipment. this is where we install all the circuit boards, and aaron is taking our front panels and putting everything together so that we can start attaching the actual circuits. synthesizers, as we make them, are electronic instruments. and they can have the form of a keyboard or they can have the form of a module that can be controlled by many things: pedals, any type of input device. the synthesizers create sine waves. a sine wave is a periodic waveform, and it's really one of the pure waveforms. sine waves relate to fourier series, which is a big, big deal in the kind of fusion of math and sound. fourier came up with this equation that said any arbitrary function or complex waveform that varies in time can be described with a series of cosines and sines. this was a very,
