Reply to launchpad out of ableton help

i am looking forward to buying a novation launchpad,
altought before i need to know a couple of things:
does all of the functions apply in all softwares? ex: the user modes, can i still use them to select the modes of all of the 64 buttons?

can i use the mixer function out of ableton? to control a knob in a vst per example

im not going to use the launchpad in music software, i want to use it with a lighting control software named martin lightjockey to trigger cues, if any of you have any experiences with that and midi, let me know
