just purchased firepod/cubase. i have four mics plugged to the firebox and i'm only able to record on one track. how do i asign a different track for each mic? also, i was recomended to purchase an extra preamp for better sound quaility. i was told the difference would be night and day. any suggestions? i have a couple of (c3000)AKG cond. mics i'm using to play around with as i'm trying to understand this new toy and expensive habit i've gotten myself into. would like to eventually record bands
