I don't actually have any Korg Tritons but from what I can see...
I actually think a Layout for this system would work with MD. There are no chained Sysex commands and every parameter has it's own address. My only slight concern is that there is a double oscillator mode that can control voice 1 and voice 2 seperately. Each voice therefore has a complete Sysex address list for all functions.
This means that because MD as of yet has no assignable Sysex variable, you would have to have a larger layout with a Voice 1 and Voice 2 panel for every value and control. It's not a big deal as you will ultimately be able to control the synth in a more powerful way.
You just need to get one control working and MD and the Triton talking to get yourself started. It gets very addicting once you get some success.
Good luck. If you need any more help, just ask and I will see what I can come up with.
