I'm not a Live user, and only beginning using MIDI controllers too. One thing comes to mind, though:
If you fire up the arturia instruments as seperate programs (
double clicking the icon from the desktop or sth like that) after you've launched Live, then the two won't "work together"; each will do its job completely ignoring the other. There might be some MIDI channels assignation conflict, or your Arturia softs not getting MIDI from your keyboard at all. On top of that, if at least one app uses ASIO audio drivers (
I'm guessing you have every one outputing to Direct Sound) only the first app launched will have access to your computer's audio output. Which is normal, and usually preferable, if a bit surprising at first.
tl;dr: arturia softs have to be incorporated into your Live project as VST plugins.
As for tutorials about integrating 3 elements (Live + arturia softs + keylab), they usually are "out of scope" of basically anywhere… neither manuals of the keyboard or Analog Lab have anything to say about that. I'd say your best bet is to look it up on youtube. If I try a search for, say, "Ableton Live keylab mkII"… damn, even that is hard, so many commercially-oriented suggestions to skim through ! >_< (
looks like I've been researching before buying) Even the Arturia channel doesn't provide much help right off the bat ;-/
If you're issue indeed stems from lauching Analog Lab/Piano V/etc. as separate programs, you might try
finding it in the "plugins" folder instead.
