I just bought the Arturia Sparkle. I installed Spark 2 and connected the SparkLE controller to my PC. Now I can't use the stop button, when I hit play and try to stop with the Stop button on the controller it's like I would hit the basedrum. I cannot use the tempo knob and the lowest decoder knob is not working as well. When I use one of the broken knobs it shows at the software but it makes no difference. For example when I use the tempo knob it will constantly jump from 120 Bpm to 121 BPM or to 119 BPM no matter how slow or fast I turn the knob.
I reinstalled Spark 2 four times and there was no difference. I even tried every single usb slot at my pc but it didn't help.
Please help me !!!!
