The MZ2000 borrowed much of it's design and features from the KN5000. It was quite the board with a lot of useful features and a great onboard sound editor to boot, which was light years ahead of any other arranger I've used and probably better than the Motif ES without using add on software ( Korg's PA80 editor lets you go deeper but is so unintuitive ) .

Notwithstanding it's brand name and its' lack of a vocal harmonizer, I think what killed it was that lacked in that one specific area that is absolutely essential in an arranger.. the styles. There were a few good ones, but most were just plain uninspiring.
