Guys,

I did try all those but they do not really respond. I also had the SD2 module and it worked perfectly in combination with the Korg PA800 just as Dan said. The funny thing is that when I set the PA800 to exterior mode and have the default piano in the Ketron, the Korg then reads 021.000.000 .Anyway I have sent an email to Ketron hoping they will answer me. I also asked them for a service manual of the Midjay Plus and behold, within a week I was sent one by email !
Rosetree I will keep you posted on further developments.

regards,
John
