Has anyone had any luck finding an external power supply to power the Keylab 49? I bought a 12v 500mA center postive adapter (as specified on the website here: http://www.arturia.com/evolution/en/products/analog-factory-experience/specs.html
The keyboard turned on but the screen was checkered and none of the pads/knobs were functional. We have used the usb connection successfully with ableton so we know that the keyboard is working.
Any advice on where to get the right power supply?
