Reply to mapping multiple controllers

hiya,

i'm using traktor 2, with a Numark omni control, and a midi fighter with the "instant gratification" mapping, and an akai lpd8 with a custom mapping for beat juggling, although they all work perfectly on their own as soon as i try and use them all at the same time, the commands from all three get muddle with each other and there is no way to separate the midi channels.

am i being incredibly thick, or is it a complicated operation?

cheers
