The easiest control is using the VST quick controls, but you only get 8 controls to play with per track. :-/
The harder method is using generic remote setup, but it won’t give you the screen feedback like the old Mk2’s and automap. The Mk3 is much more a standalone controller rather than a strongly DAW integrated design. But you can map a load of stuff using the generic remote editor, and have banks of mappings.
BUT, unlike automap they are fixed in place… Meaning that if you went from one instrument to another the mapping banks won’t automatically update - only VST quick controls do, and devices that have MCU support (not HUI).
