I have lost the use if my nanoKONTROL2. It performed perfectly just last week, and two days later it quit working. Software was not used at all between the two instances, and the nanoKONTROL was in its case the whole time it wasn't being used. I have been able to get it to respond, but only the rotary pots. The faders and the and the momentary controls are completely unresponsive. Anyone else has this to happen?
