Things have changed rapidly in the way that we record live. We used to use a separate mixer and get a feed from the direct outs of the FOH mixer to record the performance. That practice for a long time only changed slightly when digital multi-track recorders became available. Pro-Tools has become the digital recording program of choice for many years, only because it established a foot hold early. Now things have got real interesting as far as new things to come along.
Digidesign has released the live/recording consoles (The Venue Series) which give Pro-Tools users a real good way to mix and record live, of course this would be at the high end.
