Diki,

I find less of a difference between Live!, Cool! and Sweet! voices than I do with SA voices compared with them.

SA responds more deeply, and in some cases, switches between mono and ploy, and attack or no attack, based on technique...hey, I don't have to explain it to you....you know what I'm talking about.

I really don't care what they call them...they are terrific sounds, and one of the main reasons I like playing a Yamaha arranger...all companies are guilty of marketing hype...some more than others, and in different ways, but they all do it.

I was disappointed the S910 did not have the extra effects block that is on the Tyros, but otherwise, it will be a perfect instrument for meeting my needs.
