Like RC, I’m changing my mind about Korg. As a long time Yamaha player (and still am), I’m becoming more impressed with Korg, the more videos I’ve seen. Love the drums and bass parts, in particular. Thinking about adding the Pa 1000, when it becomes available.
I've always preferred Yamaha. In fact, I remember trying out the early Pa models (Pa1x, Pa2x), and there was always something artificial in their sounds. Specifically, some sounds had a strange, unnatural vibrato. But now, the Pa4x is making me question my preference. Listen to this demo carefully. I know I've already posted this long ago, but it shows just how realistic the Pa4x sounds are. It sounds like a real Jazz Trio:
