decade earlier, and much cheaper, at US$10,000 compared to the six-figure sums of other synthesizers. Whereas the RCA Synthesizer was programmed with punchcards, Moog's synthesizer could be played via keyboard, making it attractive to musicians. New Scientist described it as the first commercial synthesizer. Moog described himself as a toolmaker, designing things for his users, not himself. His development was driven by requests and suggestions from various musicians, including Deutsch (who devised the instrument's keyboard interface), Richard Teitelbaum, Vladimir Ussachevsky and Wendy Carlos. His other early customers included choreographer Alwin Nikolais and composer John Cage. Universities established electronic music laboratories with Moog synthesizers. The Moog synthesizer was followed in 1970 by a more portable model, the Minimoog, described as the most famous and influential synthesizer in history. Company decline Though commentators have praised Moog's engineering abilities, they described him as a poor businessman. Moog had pursued the development of his synthesizer as a hobby; he stressed that he was not a businessman, and had not known what a balance sheet was. He likened the experience to riding theme park amusements: "You know you're not going to get hurt too badly because nobody would let you do that, but you're not quite in control." Moog only patented his filter design; David Borden, one of the first users of the Minimoog, felt that if Moog had patented his pitch wheel design he would have become extremely wealthy. According to Sound on Sound, if Moog had created a monopoly on other synthesizer ideas he created, such as modularity, envelope generation and voltage control, "it's likely the synth industry as we know it today would never have happened". Beginning in 1971, Moog Music took on investors, merged with Norlin Musical Instruments, and moved to "less than ideal" premises near Buffalo, New York, amid a debilitating recession. Moog remained employed as a designer at the company until 1977. He said he would have left earlier if his contract had not required him to remain employed there for four years to cash his stock. By the end of the decade, Moog Music was facing competition from cheaper, easier-to-use instruments by competitors including Arp, Aries, Roland and E-mu. Big Briar, return of Moog Music In 1978, Moog moved to North Carolina and founded a new electronic instrument company, Big Briar. He also worked as a consultant and vice president for new product research at Kurzweil Music Systems
