Good old Korg...! Oh, and anyone too lazy to double-tap a switch for a function that few other arrangers even OFFER doesn't deserve the capability in the first place! Korg's system is even more capable than what you have requested, Lee, insofar as you get to CHOOSE on the fly what the Intro does. Your system, you set up the loop in the Style Composer (simple flag for one-shot or looping in the Intro creator) and that's what it does...
Korg's way, you get an OPTION. That's better, IMO...
Mind you, when are Korg going to join the 21st century and offer more than three fills for FOUR Variations (or just two and a Break/Fill, as many styles have)? Most already have six or so (and really ought to have sixteen
). Time for Korg to step up...
