I have no opinion either way on the topic of Fills on KORG keyboards but if it helps anyone, don't forget that the you have PAD's on the Pa-Series keyboards that can be used to trigger samples, one shot patterns, or even phrases that follow chord changes.

This applies to both instruments and percussion, so there are options available to function as work-a-rounds if need be.

You can run 4 pads at the same time too.
