Okay, so I have about 300-500 dollars maybe a little more, and i'm fine with new or used equipment. I need at least 4 channels of simultaneous recording at 24/96khz, more if possible. Right now I have a Sound Blaster Audigy that sucks, and i borrow a mackie mixer when i need to record more than 2 mics at a time(drums), and I have an m-audio dmp3 preamp. I keep seeing these "audio interfaces" with like 8 xlr inputs. If I bought one of those would i be able to record 8 sources at once and then just do any mixing in software- bypassing the need for a "real" mixer? This would be preferable if possible. I have USB 2.0 and Firewire on my computer. Please help with picking out quality products I could buy to fit my needs. If possible I would like something with decent converters, as I think that's why my Audigy right now sucks. Thanks!
