Simonton founded the company in Oklahoma City in 1967 and began offering various small electronics kits through mail order.

The P4700J series was computer controlled (using a MOS 6503 processor) that allowed polyphony for the first time on a PAiA modular synthesizer.

[17] For a time, the image of the audio synthesizer was that of an enormous modular system, which could take up entire walls of studios and were only available to the few musicians that could afford them (such as Keith Emerson and Wendy Carlos).

[citation needed] At a time when synthesizers from Moog Music and ARP could cost anywhere from $5,000 to $10,000, PAiA's most basic modular system, the 2700, started at $230, with prices for modules ranging from $50 to $800.

Larry Fast used this same controller running John Simonton's "Pink Tunes" program on his Album "Computer Experiments, Volume One".
