The SV-1 Editor allows you to change some properties that you wouldn't be able to change on the keyboard itself. Because the KingKorg has a display (three of them), there might be no direct need for an Editor since all functions can be accessed by scrolling through the menu's. But from my (marginal) experience, I really appreciate editor software. But, one huge downside of Editor software: You're not actually twisting and turning knobs

Sorry for going a bit off-topic.
