Controlling multiple track pitch using a midi controller

I have 5 tracks each with a 1/4 length sequence on each. So basically, one track has a single note, one has a chord, one is a low baseline and another is a kick. I want to be able to control all these instruments and the 1/4 beat sequence by using a external midi controller. Each time I press a key the pitch is altered to the key I press and the 1/4 beat sequence is played. I hope that makes sense.
