In theory, modular synthesizers have independent modules for individual functions - oscillators, filters, envelopes. Modules can be moved, replaced, serviced. If we want extra oscillators, no problem. If we want sequencers on the bottom left or the top right, no problem. Modularity is a fantastic idea because it allows us to create our own instrument. It allows us to create different work flows and gives us the creative freedom to do our own thing unlike any other instrument.
The original R. A. Moog factory was in Trumansburg New York. It was at this location the modulars were built and the Minimoog invented. In 1971, this enterprise was purchased by a venture capitalist, Bill Waytena who had formed the electronics company Musonics. Waytena moved the Moog factory from Trumansburg to Williamsville, near Buffalo New York. In 1973 Moog Music was taken over by the musical instrument giant Norlin, which also owned (among other brands) Pearl drums, Gibson guitars, and Armstrong flutes.
