Hi, i have to same problem using my Digi003 Rack. without using the internal soundcard. when it send it to my ipod and put it in my PA, it still have bleed. i just did a test and inside logic if i pan my click on one side and the backing tracks on the other. Solo the two tracks, with my monitors (Yamaha HS80) i dont hear the click on the backing track. but if i listen to it with my headphones plugged into my interface. there is bleed.
