sync emu proteus to 2500

just bought the emu proteus 2000 second hand and not quite sure how to sync it to my 2500 so i can play the sound modules sounds on ma pads and sequence them. i got the mp setup right but i aint sure what to do in the proteus.. any1 know whats up???

MPC OUT A -> EMU IN 1 (OR A)

MPC track 1. MIDI CH01

EMU may should trigger I'd of thought. Have a search on these forums as people have posted similar issues b4.
