The first voltage-controlled synthesizer was invented by Bob Moog and came onto the market in 1970 as the Minimoog. A number of other manufacturers followed his example and brought analogue synthesizers onto the market
There are ARP Instruments, Oberheim and Sequential Circuits to mention. These synthesizers could only produce one tone each and were therefore monophonic.
It was not until 1976 that the first polyphonic synthesizers came onto the market with the Yamaha CS 80 and the Oberheim Four Voice. All these synthesizers had analogue sound generation. In 1983, the Yamaha DX7 with its patented FM synthesis appeared, revolutionised the market and initially displaced the analogue synthesizers. However, the old darlings from back then can still be found in renowned studios today and are still used for modern productions. This has led to a true renaissance of analogue sound generators. Korg, Roland, Moog, Dave Smith Instruments, Elektron, Teenage Engineering, Radikal, Pittsburgh Modular, Bastl and Yamaha are some of the manufacturers that (still) present themselves on this market.
