Midi cables
MPC Midi out to Triton Midi in
Triton Midi out to MPC Midi in.
Set MPC to send midi clock (shift 9)
Set Triton by hitting global, menu, midi, external midi.
On the MPC main screen bottom left where it says "S:" change it to midi, then one click right, to where it says "off" and change it to correspond to the sequence track number on the triton that you want to sequence. To sequence another track over the top of what u have alreday done, change the "Tr" to another track and do the same thing as before
Hope that helps.
Cheers.
