Still got my MGS-64 in a little rack bag, got my KX5 remote in a little Korg keyboard bag, I want to sit in and jam with a band with a tight stage, this combo is killer!
Basically, it's close to the same engine as my old G1000, so I am very happy and familiar with all the sounds. And the pitch strip on the KX5 neck is the most intuitive bending device I've ever player. It's at the perfect angle and size to be utterly string-like (if you've played guitar or bass) and you can do all kinds of hammer on/off, trill and slide guitar things on it.
I don't care if it looks too retro eighties. To me, what matters is the control you get over the sound. This thing has no equal! I have a K2500 AND a Triton both with strips. They are nowhere NEAR as good as this cheap remote!
And don't get me started about sax emulation...!
Learn all you want about the NOTES these great sax players played, and you still know NOTHING about making an arranger sax sound like a real one. The phrasing, with tonguing, legato, timbre, dynamics, scoops, bends, screams, moans and wailing (!) just are beyond modern technology. SA is a good start, now combine that with a breath controller and a palette of sax squeaks and noises, and you might have more of a start, but that's all it is... A start.
Any sax emulation that ever gets indistinguishable from the real thing is going to be SO complicated to play, and have voluntary control over all those myriad sounds is going to be just as hard to play as the real thing.
Might as well just LEARN sax...!
