Ed,

From the way you've described it, I believe the problem could be with the G5. Hard to tell without being there and using some sophisticated test equipment.

Are you saying the same noise comes from the synth with nothing other than headphones hooked up, and nothing else turned on? If this is the case, then this will be difficult to fix.

Good Luck and keep us posted on your progress,

Gary
