Hi Bluezplayer and thank you for your reply. Yes, it is happening on all of the Styles. As I said, this is a brand new PA80.
I thought the OS could have been damaged so I
downloaded the (5) ver 2.0 disks from Korg,
re-installed them and updated to Ver 3.0.
Unfortunately, that did not solve the problem. #3 & #4 Button echos any selective voice in the right hand. echo .. echo .. echo ..

For Dan01 ... Thanks for welcoming me to the SynthZone.
