No responses from the Group, but I did figure it out. I used the Midi Setup function on the DKC100R controller and set the Midi Out to Piano Parts = OFF. It was set to ON and that was the problem. Brilliant. It works like a charm now. Love this group. I just saw the 850 upgrade unit is due to be discontinued. I think I will struggle along since my floppy library includes over 250 disks some unopened. Got the piano when my mom died a couple of years ago. A beautiful instrument just to play let alone being a neat player piano.
