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). PAiA's modular synthesizers, with prices starting under $1,000, were groundbreaking in their affordability and ease of use. 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.
