I just purchased a copy of GPO, trying to run it with FINALE on my 1.25Ghz, 512MB powerbook. I discovered problems when trying to run FINALE with GPO, not the think what would happen if I tried running Pro Tools at the same time. I'm guessing that I need more RAM, but I want to be sure before I purchase. Anyone familiar with this setup that can give me suggestions? If I need more RAM, which brands are compatible? Apple sells a gig for $700, which is too pricey. Does anyone know what brand of memory Apple uses on their powerbooks? If so, I'm sure I can find it cheaper somewhere other than the Apple Store! Thanks!
