Yes I was disappointed to see that the EC5 was left out on the PA5X, it is a "must have" for me. I have used this for many many years and I think that playing without it live will be difficult for me. Old habits are hard to break. We'll see if Korg comes up with something. Until then, my very stable PA4X will do the job for me. Not so sure the dancing crowd cares if it says 4X or 5X as long as they get their music.
