Fantom and Logic 9

Hi everyone I recently bought a MAC along with LOGIC STUDIO 9... I own a fantom g 6 and would like to use my fantom as a midi controller for the virtual instruments/drums that are in logic.. I have been on youtube and looking through the manuals but cant get them to sync up.. I have a usb cable hooked up from my fantom into the MAC..I've tried every tutorial but for the life of me cant figure this out.. What am I missing?? Any info would be great thank you!!
