I use Ableton Live 6.0.10 and am a Mac user with Leopard. I use a Tascam US-144, driver version 1.11, firmware version 1.12, and USB 2.0. My only issue with the Tascam is I cannot preview songs with my headphones. In Ableton, I have my master output routed to channels 1/2 and cue output to 3/4. I can hear the master output in my headphones but not the cue. I have tried routing my master to 3/4 and cue to 1/2, but same problem. How can this problem be solved? Can it? There is nothing in the Tascam control panel which allows me to route where the cue output goes.
