I dont understand. If i wanted to just play my empeg, i could hookit up just to a powersource and it would play? I have connected it to my pc with the powercable and the r2 whatever serial to my terminal. I have also hooked it up to my home stereo system with the power cable in and the aduio left and right hooked up to the 2 holes. Now, in either of the 2 i have seen nothing on the screen, nothing!! The only time anything happened was when i plugged it to my home steoro it played music. But i cant see anything.
