midi across all 32 faders and no sound

So, I finally got the faders to move by adding midi 1 in configuration, but if I add midi 2,3,and 4, they all move at the same time, how do I get it to work with all 32 tracks??..also the first 8 faders that moves have no sound, what am I doing wrong???, my DAW is reason 11 suite
