The JD800 is a hugely powerful synth with the unusual bonus of a useful control surface. While most of the JD's contemporaries required editing of sounds to be carried out via a single small menu-driven LCD display the JD800 crammed 125 buttons knobs and sliders onto the front panel. Most importantly, 75 of these send out Sys-Ex which can be recorded into a sequencer for extensive real-time control of sounds. A huge range of sounds can be created with this synth, characterised by digital crispness but with surprising depth. Both pure waveforms and sampled sounds are available.
