NOTE: I mapped this for my Mixtrack Pro, so I don't know if it will work with just the Mixtrack. The only changed functions are:
1. The three buttons at the top on the left and right are EQ kills instead of cue points.
2. The left delete button toggles between Browser and whatever view you were in, and the right delete button cycles through the views you have.
3. The left key lock button toggles between decks A and C, and the right key lock button toggles between decks B and D.
4. the pitch bend buttons toggle effects banks on and off for the deck selected.
5. the pitch faders are remapped to the filter for the deck. This is because it is assumed that the tracks are synced to the master.
6. The cue mix knob is mapped to change the master tempo. This is for the same reason as the pitch faders.
