Okay so the KL88 runs fine off a usb cable conencted to a PC - USB voltage output is 5v - why is it then when using a external PSU 5v does not work?? Why does it need to be 5.5 (whihc btw is almost impossible to find) 6v is too high as reported by some users as the display is too bright to read (and it has no dimming or contrast control).
Come on Arturia some solid answers are needed here???
