I have the KN6000 and I feel exactly like you. The KN7000 it's a great keyboard but for the long time user of KN like us noting very new. It's the same as KN6000 with a new look, a USB, A SD card, a video output.
But the styles is the same. I try it for 2 hours and i don't want it.

I had the KN2000, KN5000, KN6000.... and now I'm thinking of Yamaha... I play with a SD1 .. good but not for me.

I don't have the chance to see the Tyros, I think for now is not avail. in Canada ???

KN7000 is a great keyboard but if I change I will not go to Technics... I need someting different !
