Hey guys,
I'm part of a relatively new indie band, and we're looking into doing some recordings...
We attempted multi-track recordings etc using Ableton live (it came with my amp) but found that to be too complex - Plan B is to record everyone at the same time, but using a mixer so that we can get the correct levels etc (We're looking at the Xenyx 2012Fx - We can't afford much more)

Would recording everyone at the same time like this work? only the vocals would need mics - the rest of our amps and stuff have line outs to plug straight into the mixer, what sort of tips does anyone have?
Also, what problems are we likely to come across doing it like this (I know that multi tracking would be the better, but we don't have the time, or skill to do that)
