When you map (patch) your midi controls to faders (dimmers) they should all be saved in the .dvc show file. The next time you load the show on another PC, the mappings should still exist.
You can set-up maps using the Tools > Shortcuts
Also, on the Live tab, you can right click on a scene to turn Turn Speed on and then set a Speed Midi Link to alter the speed of your scene playing.
Please let me know how you get on.
