Get on it man, a weekend here and there together and you`ll have it down in no time.
Ableton is easy to use, very easy to sync up too.
It`s all just a matter of how you split your stuff down, how you arrange it, and wether or not you also want to use live vsti synths
I plit my tracks right down, but still manage to mix them in the same way as I would DJ, only I have total control over all the parts.
It`s just a matter of practice as it is a lot more work for the brain when you are in the club.
Just set the parts of each tune to the crossfader, so you can mix in and out the individual parts, but also crossfade between all the parts from one tune, over to the next, it`s really creative.
