Okay, so my band wants to record our originals this weekend. Right now I use the latest version of Garageband, a Zoom H4n, and a Macbook Pro. How would it be possible to record us all without recording track-by-track? We think it's better to record all together as if we're playing the song, but if there's a better way then please help. We're a rock trio but we're all pretty young, and I'm the techie in the group so I know the better ways to do things. But, being a sophomore in high school, I lack any type of recording knowledge. Thanks guys.
