New To Resolume, Few Questions

[meiuqer]

So a friend of my asked to VJ at his party, and i happily obliged.
Problem is that is never did something like it
I did a lot of motion graphics but none of that was interactive.
After a long search (pureData, MaxMSP, Processing, Arkaos, vvvv, VSXu, ... ) i ended up with Resolume.

But the DJ's who are playing there, they all work in different media (Ableton, Vynil, CD's). So i need to get the information via the amplifier, to my laptop.
Is this in any way possible? Can i have the video synced with the audio via the line-in (Beat detection)? And can I assigne a frequentie to an animation or effect?
And can someone explain this all to me in plain English? kinda newbie here .
Cause i really can't seem to figure it out.

a little late in replying but if i was you - and this is what i do - i would use the BPM function and manually work out what it is and setting clips to BPM.

I dont know if people use line in. I know some people use OSC but i think this is in a live performance situtation on the same laptop.

what solution did you come up with in the end?
