Hi Stephen,
maybe back to the Korgie fold?
It's a great keyboard. The 4 fills are really great compared to the 2 on my PA800. Definately smoother.
There are a number of new styles. Some actually have a similar or same name as on the old PA800, but the style is actually different.

I started doing a comparison & saving the missing PA800 styles, so I could use them on the PA3X.
Definately quite a few new ones on the PA3X.

An A/B comparison thru the same amplification system, the PA3X styles sound better balanced somehow, than the pa800.

Anyway, be interesting to see how you go.
