For live shows, mix in Ableton, or leave to sound guy

[Orion Satori]

I have a bunch of backing tracks and I'm trying to figure out how to do things. Should I mix them myself and just have one backing track with everything on it but my live vocals/guitar, or should I break up the instruments in to, say, drums, bass, synths and send those out to the house's mixing board for them to mix for the specific set of speakers/building? Thanks for any input.

Edit: I think I will, at least, put the drums on a separate track because sometimes, I'll have a live drummer, and then, I can just mute the drum track when I don't need it.

If your sound card has enough outputs Id send out the different stems to the sound guy,... unless he really sucks...lol

Its easier to mix from the FOH then from the stage. It will make you sound better
