Taike,
It's simple if you don't like it - sell it and move on. Does no good to get on a forum and gripe about it. EVERYONE knows if you buy a Ketron product you are on your own and the Italians seldom if ever, respond to user input. As for AJ - well I suspect he is doing just about all he can do and must rely on Italy to provide changes or improvements. One thing for sure, I have gigged with Roland, Korg, Yamaha keyboards and none of them provide the realism of my SD7.
Just sayin'
