Even though I have a 9000, I never had the need to use the Style Creator...but you are right, it works the same way in the 2000. The balances, however, do not appear to be memorized. It looks like you have to set the balances the way you like them when you first turn it on..and they stay set there regardless of the styles chosen. Still working on this, but that is the way it looks to me right now.

Where as the 9000 had 512 preset options, I am thinking of storing all the ones I set up on the 2000 to disk. I love the fact you can set up a second style while playing the first. Lots of options in programming a gig on the fly...and very little down time between songs. I love it.
