2 mid controllers together in logic

Alright guys. Using logic with a beheringer bcf2000 as my midi controller. All was great. Now i bought m audio's project mix. Great piece of kit but when both are working together their paths are crossing. Sometimes for example fader 2 on the bcf will move the same as fader 2 on the projectmix when they are meant to be different tracks. Am hoping to assign the 8 faders from each to be my first 16 tracks everytime i open a song on logic. Please tell me there is an easy solution and this can be done. I dont want my controllers to be fighting with each other.. Why cant we all just get along..... Cheers in advance guys..
