I have decided I need a better keyboard than the Technics KN 1000 I have. So I have been looking around, and found these three keyboards for sale locally. That means I can try them before I buy. The Ketron SD1 seems to have everything i need and everything I want, and then some.
I have done some reading in the Ketron forum, and there seems to be a lot of problems with these keyboards, especially Audya. I have never had any technical problems with so far half a dozen keyboards and synths, and I would like to keep it that way.
I think I will go for the SD1, but it would be fine hear from people who knows more about these things than I do.
