It also contained an onboard digital sequencer, one of the first of the 1980s polyphonic synths to do so. 64 patch memory locations were provided, and the Poly-800 was the first Korg model which came equipped with MIDI from the start of the production run. (Some available third-party mods fix this.) Unfortunately, in the original MIDI implementation, the synth only operates in omni mode, which means that it cannot share a cable chain or interface with another synth. Other cost-cutting measures were taken in the materials, which had the unfortunate effect of giving the synth a cheap feel. The casework was lightweight plastic, and the pushbutton switches of the one-knob patch editing interface were flimsy most of them had to be replaced after a few years of use.

The synth did have the advantage of being lightweight and easily portable it could run off of batteries, and it had provisions to attach guitar strap buttons so it could be played as a keytar. It had a 49-key, C-to-C keyboard (some were made with reverse keys), and used the same pitch / mod joystick as the Poly-61. The original version of the Poly-800 was introduced in 1984. The next year, this was followed by a Mark II model which added an onboard digital delay line, which could be configured to produce flanging, chorusing, and 'slapback' echo / reverb effects. The Mark II also expanded the MIDI implementation, adding the ability to edit parameters and dump / load patches via sysex messages.
