If I understand the one answer as using the styles off of the 3000 but using the Korg for the sounds in those Yamaha styles, I can tell you from experience that it is a lot of confusing work.

I tried the above idea using a Technics KN2600, which to me sounded like a low end Casio, but had pretty good styles. I thought I could use the Technics styles using the Tyros sounds in the styles. It kind of worked once or twice but even the techs at Yamaha and Technics were not of much help with this. I gave up.

If that is not was meant by George's response then take it for what it's worth. Although after what I have experimented with in the past, I will never ever again try using midi cables between two arranger keyboards nor would I recommend it to anyone as a good quick way to operate in a live situation.
