The Poly-800 is an eight-voice instrument with 64 memory patches and up to 50 editable parameters! The Poly-800 has one DCO per voice. The analog filter is a 24dB/oct low-pass which is shared by all voices. There's also a stereo chorus effect, chord memory, a simple built-in sequencer, three digital envelope generators, and a joystick used to adjust the pitch, modulation and the filter.
The Poly-800 has light-weight plastic case (only 10 lb.), a couple low-profile sliders/knobs and 49 keys. The Poly-800 can run on batteries and has guitar strap pegs so it can be worn like a keytar. Comes with the original preloaded factory sound data cassette tape and the Power Supply.
