Can any body help me I have a wx2 keyboard here is the problem: I can turn it off and on and it will play the default sound set that first comes on but I can't access any of the other sound sets or any other functions such as transpose, effects, mixer, ect. the button are non responsive and if they do respond it is not for the intended purpose such as when I press the clock function I get edit sound or if I press the status function I get the arrange function I is there any way possible to repair this?
