Korg | Poly-800 mkII


The Poly-800 mkII is an eight-voice instrument with 64 memory patches and up to 50 editable parameters! The Poly-800 had two DCOs per voice, instead of the single one in the original. The analog filter is a 24dB/oct low-pass which is shared by all voices. There's also a stereo chorus effect, chord memory, delay, a simple built-in sequencer (inceased to 1000 steps), 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 mkII 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 mkII can run on batteries and has guitar strap pegs so it can be worn like a keytar.

The mkII also added MIDI SysEx functionality and a darker paint job.

Velocity As with a piano, the harder you hit a key, the louder the sound, unlike most organs which always produce the same loudness no matter how hard you hit a key. Aftertouch Pressing a key after you activated it. Channel Aftertouch, no matter which key, it will send a Channel message. Poly Aftertouch, sends the pressure per key instead of the whole channel.
Values for OSC, LFO, Filter, Envelope are per voice unless stated otherwise.
