Yes, it's only a few weeks old, so should be under warranty.
@Triryche Yes, it's the black faced one. I had some updates when I first connected the UX1, but no more after that.
I am the following driver level now:
Drivers: 4.2.5.4
USB Firmware: 1.01
Line 6 Monkey: 1.62
POD Farm 2: 2.55
I think the faders are fine, but if there's anything I can check, I'll check it :)
