I'm trying to create backing tracks for live performance in garageband. I set a separate track to quarter notes as a click track, but when I mix it to left or right (to isolate it) it still comes out a little bit on the right.

Is there any way to completely isolate a track in the mix?

For anyone who understands garageband, but not specifically what I am trying to do, I want to be able to send all tracks minus the click to one side (say right output) and all the tracks including click to the other, for my monitor or headphones.
