Re: Korg Poly-800 mkII // Digital Line Noise Issue...

have you tried using the MII in a different location/room/outlet (if on AC adaptor). How about running on batteries? Any evidence of someone inside the unit? Maybe left some shielding out? My MI Poly has a huge flat shield under the main PCB and another above the Chorus Board. Any shielding wires unhooked?
Does the sound change when the LED's change or program change/parameter changes?
