You must remember that music gear you buy now was actually first designed some years ago and is based on technology at that time and not now. And by the time that products in design now arrive, they will reflect what is available now and not what is available at the time they hit the market.

Computers change every couple of months, but this is not the case with electronic music gear due to to design and marketing considerations. And I'm not just talking about Ketron but gear from ALL manufacturers.
