Thanks , I do a reset and see what happens. I've been playing this keyboard since. 2003, and I never noticed this. I know I never would hold a note, or chord that long so maybe that's why I never caught it on stage, but now I'm only doing studio stuff in my little studio I'm hearing this. It really is not an issue for me , I was curious if anyone else experienced this. And I'll also check into edit the piano voice. Maybe way over due for an upgrade , hmmmm. Oh honey can we talk.....................? Korg pa , or a new yammie.
