interesting, to me there is no difference in performance from x2 to x3. it works well, but some of the buttons don't do what they are supposed to do. it's been that way ever since I got it probably during 8 or 8.5. the c4 audio seems unchanged. I'm pretty happy, but occasionally when I get too frisky with the jog wheel, or too many buttons too fast, I get a crash. not often.
