Yes, what you want to do can be done in both LivePRO and LAStudio using a concept called "Channels".
Please take a close look at the LivePRO help file.
Data can enter LivePRO from either MIDI or DMX and then be routed to "channels". Then these "channels" can be routed to LivePRO functions, effectively allowing you to get data from the outside to inner functions.
"Channels" can be used in the Abstract Generator and Color Cycle portions of LivePRO. Near certain sliders you will typically see something that says <none>. This means that "no channel is controlling this slider". If you click on that, you can assign a channel to particular sliders and functions.
Best regards,
