Audrey,
Good advice, I have always been into buy and sell and trade ending with the best, but not for long � I even owned a Wersi Delta 500 organ and a Wersi keyboard but no more. The Kn7000 is going to stay it�s for me to enjoy.
I wonder what it would take a group of electronic engineers to add (not change) some of the up-to-date features to a Kn7000. Expensive, but there would be many that might make a commitment to buy the finished product.
Just dreaming, John C.
