While finishing "Slipping Away" off, I felt myself really hitting the limits of my system, both hardware- and software-wise. As I came up to around 30 software instruments in Garageband, it started complaining that the limit was reached. I could easily fix this by chnaging the upper limit to 64, but when it came to applying EQ to each track to better mix them together, it just wouldn't accept it, giving the old message that there are too many tracks or effects. (And that was with each track "clean", no reverb or anything except for the EQ.)

Now, I could have bounced each track to audio and imported those back to GB, but there is another limit: disk space. 40 tracks, a 3-minute song, assuming each is mono would be something like 40 x 15 MB, around 600 MB. Well, not that bad, but without any method to streamline it, it would be a big hassle.
