Hi guys, thanks for the feedback and interest. I have tried other SD cards and they have the same effect.
I agree that a KN7 without the SD card is no less than a KN6500
OS with all the extra benefits of the KN7, which as you say should have some considerable value.
I thought about keeping the two, BUT!!! we don't have a lot of spare room in our compact retirement villa (asylum)!!
I have studied the u-tube posts on the Korgs and it frightens me to have to learn their system, Technics has it all over them but there is always new technology coming out which draws you to the new 'boards.
I am mostly a home player but it would still take me months of work to recreate all of my registrations. Once before I accidentally lost all of my regos on floppies and had to do them again. It took me an age and I was very cross with myself.
I will still investigate a card reader replacement, but i don't hold out much hope. Keep praying for me!!!!
