you are being overly harsh. These are not bad demo's and its very very good news that young people are using ketron ptoducts. They actually have a current and future market if the young people grab a hold of these incredible instruments and develope styles and features relevant to this market. Yamaha must know there is a real problem with their current target market profile . There are only so many times they can recycle the same product and get people to churn their previous model for th next one . I think Ketron have made a major step forward maybe not in the instrument itself but in changing its appeal.
