I've tried the KN7000 and I think it's a very good board in many areas . However what makes me hesitate compared to the Tyros is mainly two things.
There is almost no support for the KN7000. I don't know of any commercial or free styles developed for the 7000.
The 7000 doesn't have a music finder similair to Yamaha. The technics music database is not near as useful.

Another extremely strange thing, especially for organ players like me, is that Technics claim it to have easy pedal board support and it have midi pedal input. However the 7000 doesn't have any manual bass funcion and it doesn't have a bass part selector with the L, R1, R2 selectors. Also the drawbars and tabs can not be used for the bass part. How to use it as an three manual organ in an easy and simple way?
Technics this is really stupid !!!
