It was working until yesterday…
When I connect the power and turn it on by pressing the button, nothing happens. Literally nothing.
Yes, I've tried different outlet, and I know for a fact that the adapter works because I tried plugging it into my MIDI keyboard and it works fine. So I know it's an issue with Kontrol.
Fortunately it's been only about eight months since I got it and is hopefully covered by the warranty.
Does anybody know how to file a warranty claim, if such a thing exists?
