MEGX audio/power issue

I'm having issues with no audio passing through the MEGX whatsoever when power is connected to the regular power input. The unit will "bypass" without any power source connected, but the moment a power source is introduced to the regular 9v input, nothing passes through loops or the output (if all loops are disengaged).

What might I be missing here?
 
It sounds like there may be a problem with the MEGX. Try unplugging everything from it except the guitar and amp and see if that changes anything. Also, check your settings, make sure that the input or output is not programmed to be turned off.
 
You nailed it - I found a sneaky "outputs off" program change being sent by the MMGT on powerup and it wasn't updating the preset from the computer because of a faulty USB cable. All sorted out now, thank you!
