I am new to Macs. I was wondering if one of you audio tech savvy guys could help me understand something. Back when I was a PC guy, if I wanted to spare the CPU from doing all the work I bought an internal audio card (interface) . The card then ran in ASIO with virtually no latency. I could pile a multitude of tracks and tons of effects, while the CPU bar barely budged forward, and the music barely even hiccuped , even with only 512 megs of ram. My question is, how do I get the same result with my MacBook Pro? If I bought a firewire 400 audio interface would that take the pressure off the CPU, giving me better results? Or would I need a Firewire 800 express card? Or is this possible?
