Right ok...... from that I know that the USB is creating a very short loop in playback......... Anyone know how to stop this loop effect so that I can adjust settings in POD EDIT rather than bending down all the time and tweaking the knobs on the HD500 which at my age is a pain lol. Come on Line 6 sort it out. If you do ill be able to put the HD500 back up there with the top stompers in the world lol.
