Another plus with Korg basslines is that they're not the same pattern in both major and minor keys, or from variation to variation. And I'm not just talking about the obvious flattened third involved. I also like the easy adjustment of bass turnaround points.

Also, if your Korg has a style called Bebop1, variation four provides four bar drum breaks (four different ones), so you can trade fours between your lead voice and the drummer. Very jazz, very cool.
