Batteries would be great--but if push comes to shove, I can haul around an extension cord. (I'll probably do so anyway--recording is kinda battery-intensive for my laptop.)

By default, the plugs I've got are 1/8", line level. However, there's always adapters. Mixing a mic will be a must--for starting out, it will probably be a good computer mic due to cost. All told, I can't imagine needing more than four sources (two music, two mic). I can do without crossfading--never used it in the studio, so I doubt I need it now.

Thanks for all the help!
