Reply to YAMAHA EX5 with traktor

I want to be able to use my Yamaha EX5 to control Massive's macro settings in a live setting.
I have my EX5 plugged into my Audio Kontrol 1 via MIDI, and have Massive's output routed into Traktor via Audio Jack. Now my issue is, the second and third knobs as well as mod wheels 1&2 on the EX5 are controlling functions in traktor as well as my massive settings, interfering with playback.
(Example: Knob 2, which controls an LFO in massive causes deck A in traktor to play/pause when turned.)

Is there a way to make sure that the EX5 is controlling massive exclusively? or at least be able to change the functions that it controls in traktor?
i have nothing mapped at the moment except for the genric keyboard setup.
