So I put GarageBand on my 450MHz 512 MB RAM Beige G3. I got rid of all the apple loops and some other stuff for now, though, because my hard drive space is very limited. I hooked up my guitar, added new track, chose real, then guitar. I can listen to No Effects and Accoustic Guitar Echos, but any of the other effects get all distorted and crazy. At one point, I actually got a Kernal Panic. So is this happening because the computer doesn't have enough oomph, or are there certain files I'm missing?
