Syncing to Acid 5

anybody help me!... how fo you set up the MPC 2500 and acid, so that when you hit play on the MPC ACID starts?

Thanks in advance

midi clock....set it up in Acid,,but as an Acid 5 user it sucks, and the syncing is bad... But if you have a loop region and place the cursor right at the end of the loop region, and then hit the spacebar, when it loops to the begining it should right on time.. But if you start right at the begining Acid lags...I personally find Ableton syncs up quite nice, but i do use both on a constant basis...
