This new Korg sounds great (like all Korg arrangers) but not much new under the hood. I think that most of the increased waveRom is for the Kronos Grand Piano.
Probably, that was the case with the Krome, too, compared with the M50. 2 GB spent for the grand piano, several hundred MB for e-pianos, and not much for brass, strings, woodwinds etc. I hope it's distributed a bit more evenly here.
