If you go on the korg website you will find FOR FREE, just about every style that korg has made and they keep updating new styles at no charge.
Now that's wjat I call pro. No really i played yamaha until korg came out with the pa900 and before yamaha I was a technics guy until they stopped making them and I found after working for a while with the korg, I was able to find just about any style I could think of. It is not a keyboard you can just sit down and play without a little bit of study.
Yamaha was easier but not as deep and you can't go by korg style names. They are very misleading and all over the place, and that might be why people think yamaha has better styles, because they just can't find them in the catigory they should be in. Just my experience
