First of all let me say this:
I sympathize with UD's remark towards Diki and Fran: do you always have to drag in your affection for Roland ? And I mean no disrespect to either of you , let that be noticed.

As to the Korg accompaniment being too busy, here is my simple view. On the outset of this century most of the Yamaha styles were pretty monotonous in the sense that they only covered one (two at the most) bars and in the sense that many of the acc. tracks were simply empty and (at its best) came in during variation 4. Do you realize how much more demanding it is to have to add new tracks to a style yourself than it is to simply eliminate one or two acc. tracks from an existing style if you think they are too busy ? Korg's styles have always been varied on both counts. They cover 4-8 bars and yes they are generally pretty well filled up. But as mentioned here, it is dead easy to mute some acc. tracks ( one second each !!!) and have an acc. that is less demanding and more quiet.
