Released in 1981, the Pro-One caused the industry some surprise, given that Sequential Circuits (SCI) had been promoting their larger, more expensive polyphonic synths since 1978. I guess the Pro-One was SCI's attempt to bring the technology of the Prophet 5 and 10 to a wider market.
Introduced at the 1981 NAMM Trade Show, the Pro-One is said to be the world's first synthesiser to sell for under $1,000. The original price tag was $645, but this increased to $745 and it is estimated that over 10,000 were made and sold.
Although the build quality of the synth has been criticised, its internal sound architecture is beyond reproach.
Using the same VCOs, VCFs, VCAs and Envelope Generators as its bigger brother the Prophet 5, the Pro-One has endured the test of time as well as any of its Moog contemporaries.
