HELP WITH SETUP

wat up......I have an mpc 1000, m-audio keystation pro 88(midi controller), mbox(pro tools le), powered monitors and reason 3.0. Am tryin to set everything up but am not getting any sound from nothing. I only get sound when I hook up the mpc directly to the speakers. I've tried almost everything.....somebody help

i take it your sending sound through the mbox to the speakers so i think u need to make sure that reason is recognising the mbox so it will send sound through it i think it's under the audio tab and make sure u got the speakers hooked up right to the mbox
