So I'm gonna try and set everything straight. A digital 8-track is good for ease of use, can export to computer, cost from $300 to $400. USB Audio Interfaces are cheaper than digital 8-tracks, but are harder to use/get the hang of And firewire is similar to USB. What I still don't understand is the whole process for the Audio Interfaces. Do they keep tracks within themselves? Where does it record onto? I'd like to stick with the USB or Firewire stuff because its cheaper, and I'm on a limited budget. And I wanna get a ZIM.
