While it is possible that the styles might have got re-programmed to at least not exacerbate the problem, the fact remains that Korg STILL have a system where, unless you forego the Break/Fill, you only have TWO fills for the entire style. This is in comparison to Roland's seven, and Yamaha's six (and a Break/Fill).

For my mind, this is not enough to make most of the transitions (there are 16 possible transitions on a four variation arranger, including Fill-to-same) as smooth as those higher count fill arrangers can. I am sure, when coming FROM a Yamaha or Roland to a Korg, the noticeable drop in fill numbers cannot help but be noticed.

But to offset this disadvantage is the Korg technique of using MUCH longer Variations (up to 16 bars or more!), so you don't NEED to press Fill quite so often. But, essentially, if you think about it, two fills (one up, one down, I guess) will always have SOME kind of jarring effect. Going from Var4 to Var1, a very pumped up fill would work (you are coming from a pumped up Variation, so the entry into the fill will flow). But that exact same fill, from Var2 to Var1 will sound out of place, because Var2 is still a nice laid back Variation.

Every other arranger manufacturer has figured this out. Why are Korg clinging so desperately to this out-dated system, and yet offer innovation and common sense to so many other aspects of arranger making? It, IMO, LONG past time Korg came down from the clouds, and joined the rest of the industry in offering enough fill choices to make most of the fill transitions at least a smooth as the competition.
