I have a question. I have a G5 IMac and I'm currently using Garageband. I actually have Pro Logic, but working my way up to that beast. My question is this. . how do the Pros connect to their Macs? There is the (line in) import that uses a 1/8 in. jack adapter with the guitar cable or mic cable plugged into it. I was looking into a firewire interface or a USB interface. I will get a lot better sound by doing that than the line in import on my mac correct? Also, which is better?... the Firewire or USB? Thanks for any help.
