Hello, I just bought a Arthurian key lab 49 midi controller and I have installed Analog lab software, my problem is everything else is working apart from the keyboard, all the nobs, mod and pitch wheels and pads are working. I do get sound when i press the virtual keyboard on the computer but no sound when I press the controller keys. How do I get this to work, I have gone through the manual but cant get it to work. Any ideas please
