In Audya, it's both live drums and guitars. Plus there is a wide variety available.
A style called Kramer is a good example. It has been on all models since at least SD1, and there is an audio version on Audya.
I haven't found anything similar on Korg yet.
There are also some of the old-style country shuffles with walking bass on all or some variations. Nothing like this on Korg that I've found.
