Dazart,
The Tyros is a wonderful instrument which seems to be ideally suited for singers who accompany themselves and for the most part populate the Arranger Forum. I don�t think Tyros players would argue that the sequencer and sound editing functions on the KN7000 are more versatile and easier to use. The big question seems to be which instrument has the piano, drums and styles that suit your taste. In the hope that some of these question might be answered, check the KN7000 Demo on the mp3 page of www.kool-keys.com.
