Hi want to do that chain so i can record the line 6 pod xt through the line 6 ux 1 into garage band. My currently way to do it is line 6 pod xt left output to line 6 ux1 guitar input and usb into my macbook. i have changed the audio in in garageband preferences to the ux 1 and the audio out to my computer. when i choose virtual instrument, then whatever i do it just keep scratchung in the speekers, i cant get any signal through. please help. this should work!?
