I haven't yet tried this, but I think if I needed to have separate tracks, I would record MIDI first on one track and then re-record each track using the MIDI performance to trigger the DM10. I'd look into using something like MIDI-OX to only allow one note at a time (i.e note 38 for snare, etc.) for each track.
or you could just mute the unwanted tracks with the mixer..
Theoretically it should work, but like I said, I haven't tried it in real life yet..
Good luck!
