Why do I get a message that Loop Stereo is not available in the X slot, when nothing is plugged in to the Aux input?

  • Well, I tried to establish " Loop Stereo", in the "X slot", but there was a message in the main window, "Effect loop not possible, Aux input is used". Well there is nothing in the aux input, as I am using only the Front input, and that is verified in my "Input setting". went through all system and rig settings, and saw nothing that would indicate the Aux input is being used, and there is nothing plugged into the Aux input. Could this be some sort of "bug"? OS release 6.0.0.14574. Any ideas why?
