Which kind of Interface did you use on live gigs?
Gavin Says:
use an M-Audio Firewire 410. It hasn't given me any problems at all. We use the same box with PT. It isn't unbelievably hi-fi and you're going to need to use a couple of DI boxes to send the stereo mix out to the PA. It's important that you choose a box that has more than 2 outputs - because obviously you want to send a stereo feed to the front of house and have a separate output (or two) to feed your headphones for the mix with the click in it.
This box can run off the firewire bus and that's important too - because if some clown trips over your power cables in the middle of the show (and it has happened more than once) the laptop will switch to battery mode and still power the M-Audio box without interruption. Another scenario is when you have your box powered by it's own power supply (like the MOTU 828) and if the power gets interrupted (for even a fraction of a second) the laptop will switch to battery power but the MOTU box can't. So it loses communication with the computer and no sound comes out - and then you have to restart the laptop (which can seem like forever if you're in the middle of a show).
