Reply to Need some help please

I have a behringer ddm400 and am looking to get either a m audio trigger finger or akai apc40. Im really split between the two. I first want to make sure that i can manipulate songs (cd, mp3, ect) with either controller. I want it for more than music production. I also want to make sure they can be connected through my ddm400 and what cable is needed. Just need some help figuring out which controller is right for me and how to connect it to my mixer and computer, any help is greatly appreciated
