Korg Poly-800

Poly-800

At a time when Roland was doing well with their Juno-series, KORG countered with a poly-synth of their own in 1983 with the Poly-800. The Poly-800 was comparable to the Juno-106, at the time, with respect to the fact that musicians now had access to affordable programmable polyphonic analog synthesizers (it listed for under $1,000) with memory storage, stable DCOs (digitally controlled oscillators) and a new state-of-the-art technology called MIDI (although there was no SysEx implementation yet).

The Poly-800 is an eight-voice instrument (two more than the Juno series) with 64 memory patches (half of what the Juno-106 offered) and up to 50 editable parameters! Like the Juno, the Poly-800 had one DCO per voice, although it did feature a Double mode in which the oscillators could be stacked up for a fuller sound and only four voices of polyphony. The analog filter is a 24dB/oct low-pass which is shared by all voices (the Juno has separate filter chips for each voice). There's also a stereo chorus effect, chord memory, a simple built-in sequencer, three digital envelope generators (for the oscillators, the noise generator and the filter), and a funky joystick used to adjust the pitch, modulation and the filter.

Unlike the Juno, which was still a “studio” instrument, the Poly-800 was built for the performer. With a light-weight plastic case (only 10 lb.), a couple low-profile sliders/knobs and only 49 keys, the Poly-800 can run on batteries and has guitar strap pegs so it can be worn like a keytar. A less common reversed color keys model was released for a unique look as well.

EX-800

In 1984, a keyboardless tabletop/rackmount version was released, called The EX-800. In both the Poly and EX models, all sound editing is accomplished by scrolling to a given parameter, described by little more than a two-digit number, and pushing the up or down buttons to adjust it. Fortunately every parameter’s two-digit numeric code and data-range is printed on the faceplate. Obviously, the Juno series has the edge over the Poly-800 when it comes to hands-on editing, however, some sort of external MIDI controller is usually sufficient to get more hands-on and real-time control.

The Poly-800 model was succeeded by the the Poly-800 mkII (pictured above) in 1985. The mkII added digital delay effects, MIDI SysEx functionality and a darker paint job. Note that the Siel DK70 is very similar to the Poly-800. Poly-800s have been used by Orbital, Depeche Mode, Sneaker Pimps, Vangelis, Geoff Downes, Nick Rhodes (Duran Duran), Yesterdays and Jimi Tenor.

Is the EX 800 the rackversion of the Poly 800 or the Poly 800mkII?

Bought mine new in Nov '84. Still have it. I now own Oberheims, a Kurzweil, and several other Korgs. The Poly-800 clearly has its limitations, but then again, every other synth I own has its limitations. They each have their strengths, as well. Anyone who even suggests that the P800 is difficult to program is brain-dead. It is probably one of the best synths for learning programming and basic synthesis. As far as sounds, I own 2 P800s and 2 EX800s. Try midi-stacking them and hear what happens. There are some very cool things one can do w/ more than one! Then add FX! Amazing and cheap!

Hey everyone, I have a poly800-II, but the tuning slider doesn't work. Also, the joystick only works for pitch-bend, not vcf/dco (up/down does nothing).

Has anyone tried fixing this or know of repair-forums? Thanks! :-)

The description here really, really should include the jaw-dropping limitation of having the one filter for all the DCO's. Strangely though, I didn't really mind this almost unforgivable limitation on a poly. Maybe it's the relatively small size, the mock calculator font, or the odd way of building up oscillator wave's, but it's an endeering little synth which does very reasonable basses, filler pads/strings and tamer leads. With a mod or two it becomes even better. Still at a low price, where it should be, this is a nice starter synth or fun synth on the side.

Tesla Boy also uses a Poly 800
