Roland JD-800

Released in 1991

The JD-800 is a 24-voice digital wavetable synthesizer which mimics an analog polysynth, using dozens of dedicated sliders for sound editing. It has 108 different PCM waveforms, and a multi-mode filter. Its five-octave keyboard responds to both velocity and aftertouch.
