I noticed a few days ago that knob six on my Kore 1 controller was acting very erratic. For example, when slowly turning the knob clockwise, the values start at 0.0 jump to 0.15 jump down to 0.10 and then smoothly go up to a little over 0.22 before it jumps directly to 0.8 and then just as erratically makes it way up to 1.0. Ugh, that sentence doesn't make much sense, but all the other knobs increment very smoothly from 0.0 to 1.0 when turned clockwise. This happens in MIDI controller mode or running inside of Kore 2.1.2. The driver version is 2.0.15 running on Win7 x64. I have tried different USB cables, all are plugged directly into a USB port coming from the motherboard. Some are explicitly labeled as USB 2.0. I also installed Kore 2 from the CD (without updating to 2.1.x) and an older version of the driver onto a different computer running Win7 x32 and see the exact same behavior. Unfortunately this is feeling like a hardware problem to me. I have put in a ticket with support over the weekend, but haven't heard back yet. Has anyone else experienced anything similar, and if it was a hardware problem, how did support handle it? Obviously I'm out of warranty, which has me worried.
