I don't think this can be done, however, you might beable to use the Triton as an outboard effects devise and use some of the effects on the MPC. Other than that, I doubt it and would imagine that you have to redo the sequences on the Triton.
The only thing I can think of is to convert the MPC files to WAV. files and try to load them. I cannot tell you how to do this and I can tell you it is probably not that easy. I attempted to make a wav. file from my computer and then load it so the MPC but that did not work I believe it can but it needed more work and I was unable to give it the time it needed at that point.
Anyway, good luck. If I come across anything that might help and send it over.
