ok dawgs.. i was thinking of ways to get more creative with DJ'ing. so the latest thing i was thinking was: route the master from my dj mixer into Live and have a bunch of plugs on that master channel hooked up to a MIDI keyboard/controller. had a few questions about this, if anyone has any experience with this sort of thing.

How can i route the audio with zero delay? currently there's a big delay when i hook up the mixer to a USB soundcard.

Is there a way to automatically make Live detect the BPM of the live audio coming in through an audio channel and thus change the Global BPM in Live?
