One of the upgrades I liked most about the Tyros4 from the Tyros3 was the former's ability to use SA/SA2 voices in the styles.

Let's face it, an arranger keyboard's soul is in it's styles.

Most of the T4's preset styles use SA/SA2 them to great effect, as do the Premium Styles, and, of course, with Style Creator you have a lot more tone colors to work with.

I'm still exploring and enjoying even after almost two years.
