Atterion said:MIDI Out from the module to the MIDI In on the Triton. Make sure both are set to the same channel (Probably Ch10, which is the default GM drum channel).
Korg's Combi's let you assign each program component it's own MIDI Channel (I.E. the first half of the Combi set to Ch.1 for use via the Triton's own keyboard, and the second half set to Ch10 (or other) for triggering via your electric drum pads).
