Either it IS easy enough for the average user to understand, in which case, it should NOT have been hard for Korg to quickly redo all the styles to use it, or it IS complicated, but even so, Korg (as the inventors) should have had enough time in SIX MONTHS to revamp more of the styles since they released it....

What you are saying is that, for six months, Korg haven't revamped a single one. I would have thought, just to move them off the shelves, re-doing the entire library should be considered by Korg as an investment, not a chore for the more gifted users to HAVE to do

Let's face it, if it were that easy, the users would have done it by now...
