The control surfaces typically comply to a certain protocol. The supported protocol for Mackie control is Mackie control. The Euphonix MC control/Mix support EUCON, Mackie Control, and HUI. They are designed to work inside a daw. The parameters of soft instruments, faders, inserts, etc... are all automatically mapped across the faders and/or knobs when the desired functions are selected. Basically, if you can map it in you DAW to be controlled you can then control it on the Surface. As for direct MIDI mapping... I do not think it is possible on either surface. Although, I haven't used the Mackie Control in a while. The control surfaces are designed really for fucntionality of controlling your DAW (Logic, Cubase, Pro tools, etc...) and not as much for performance. If you want something that can do both, you would probably go to something like a keyboard that has controls. The Novation Remote SL series works very well for that. If you want motorized faders and midi and auto mapping, then the CME VX series is pretty decent.
