i'm using Logic 7 Pro with an MBox 2 on a PowerPC G4 laptop, 1.67GHz processor and 2GB of RAM. and yet I have to constantly freeze and unfreeze my audio instrument tracks if i try to use more than, say, 3 or 4. and it drives me nuts. what kind of desktop computer can i get that will allow me to use, say, 9 or 10 looping audio instruments without having to freeze? or is there ANYTHING i can do to improve my laptop's performance? any advice is highly appreciated..... i am feeling stymied by my computer's performance. it's baffling because ProTools rarely runs out of power, but these audio instruments just kick my computer's butt.
