Yo, S.K I sent you a PM a couple days ago... did you get it?
anyway here is the info that helped me...
TRITON :MIDI OUT to MPC MIDI IN
MPC: MIDI IN to TRITON MIDI OUT
This is the most important step: Turn the local control OFF on the Trion. You can control all 16 channels of the Triton via MPC. In seq. mode of the Trion, just make a program on the MPC and lable each Device Triton_1, Triton_2, etc., etc. Hope this helps! peace
(Just change the local control to off) change the drums in the MPC to MIDI and then bang away... but whgen you bang do it in the main COMBI or PROG mode, and then when the MPC records the MIDI data go into sequence mode and then chose the sounds that you want(and make sure that they correspond with the drum channels in the MPC) after you figure out the first part just just play with it a little bit and then you will start to understand it a little more.)
I posted you question on a couple of different sites...
