Help with Live, ABL and M-Audio O2

I'm hoping somebody can help me out. I am running Live with Audiorealism Bassline with a M-Audio O2 controller. I have the track with ABL set with the monitor on and I am able to control ABL's knobs with the O2, however, I can only hear the audio when the track is armed. Consequently, when the track is armed it records the knob movements, but I don't want it to record the movements. I want to be able hear ABL's audio and control the knobs with the O2 without Live recording the knob movements. Is there anyway around this? Any help is greatly appreciated.

I figured it out. I had to turn midi overdub off, keep the track monitor on auto, arm the track and voila!!!
