...Hey, I just got my first Mac 2 days ago and I've been making beats on GarageBand, just kind of fooling around and such. There is one song that I'm working on where all of a sudden I can't hear any of the tracks during playback unless I solo them all. I didn't change any settings or anything. Anyone know how to remedy this? Any help is greatly appreciated. - Q edit: I should probably not that I'm using only software instruments and I cannot hear sound when I'm not recording if the track is not soloed. I have two other songs going and I do not have this problem.
