Problem with Midi Beat Clock from Protools

I am trying to do a remix using some raw vocals inside of Protools and remixing the beat on a MPC 4000. The MPC is the slave, I am sending Midi Beat Clock out of Protools(Mac) and the MPC ends up playing almost double time even though tempo from Protools is set to 93bpm, the same speed as the sequence in the MPC. Has any one had this problem before and does anyone know how to fix it?
