There is one major disadvantage I like totell about Tyros. Not that I have one. But I got it as inside information: the hardware of the Tyros is toy-stuff. Button break out, the prints and cables inside.... it all cannot be compared with the KN7000, with is much more rugged, has a better keyboard. By the way see the website of my keyboard retailer, who offers such great customer support and help:

I built this website and webmaster it as appreciation
