Any VJ's out there?

Hello, my friend is a VJ for most of my DJ sets, he mixes video live much the same way a DJ mixes music. He is trying to get his APC20 to work with Resolume / Ableton to control the launching of video clips / effects / etc. The promlem is there is very little to no info out there on how to do this. Is anyone on here familiar enough with this to maybe offer some advice? Thanks!

there was a thread here the other day about a guy who made a plugin for ableton to launche clips on the apc20/40. I think it's called grid or something.

Resolume is legit but a fucking HUGE resource hog. I would have him move over to modul8 or grandvj
