During the time of the Roland Juno series in the mid-80's, Korg offered the Poly-800. Comparable to the Juno and in many ways better, the Poly-800 is an 8 voice polyphonic analog synthesizer with 64 memory patches and up to 50 editable parameters! There's also a stereo chorus effect, a sequencer, and a weird joystick used to adjust pitch, modulation and the filter. There is a double mode in which the oscillators double up making 4 fat voices of polyphony - fun for trance and techno.

Extended information

Then in 1984 came the Poly-800 mkII (pictured above) which added digital delay effects. The rackmount EX-800 version (pictured below) has a built-in 256-step polyphonic sequencer. Poly-800s have been used by Orbital, Depeche Mode, Sneaker Pimps, and Jimi Tenor.

Even more rare is the Reverse Keys version of the Poly-800. Its specifications and features are the same as the original. Only the key colors are reversed.
