I have been trying to use my mac with garageband to record my band for a while now, all with sub-par results. Right now I have our guitar, bass, drum mic (1 overall until we can afford a decent set), and vocal mic all running into a Mackie CFX12 Mixer. From there, I am running the (component, a.k.a. RCA) "Tape Out" to the 1/8" mini-jack audio in on my mac. In garageband I create a new 'real instrument' track. From there, I just hit record and we play. Afterwards the audio quality is quite poor. I am sure it isn't the cables or the mixer [being broken], and I am quite sure I am setting all gain, as well as all other settings on the mixer correctly. I am thinking I may have to buy an Mbox, or something to run the Tape Output or Speaker Output to in order to get a clear and digital signal. All suggestions are appreciated. Thanks
