I would like to record my band, live, in a multitrack format with my laptop using Sonar as my software. I've determined that I need some type of interface in-between my mixer and my USB port, the majority of which (USB interfaces) seem to only have 2 inputs. Is this maneuver even possible considering that the drums will take 6 tracks, 2 guitar tracks and a bass? The vocals I would lay down afterwards. Should I be considering the purchase of a "stand-alone" digital multitracker? If so, do I then record the tracks from the "stand-alone" into my PC via an interface, (2 tracks at a time), to master them in Sonar? Thanks for any help anyone may have!
