256 ram should improve things, though it\'s somewhat problematic running the two programs on the same machine. Logic 4.0 doesn\'t seem to work right with Giga at all. Logic 3.6 works better, I\'ve found
I don\'t use Logic 4.0 because I\'m not a heavy hard disk recording guy and I don\'t need all those plugins, etc. I\'m using 3.5 and I\'ve had no problems running it with GS. I\'ve got a machine with a Pentium Iii 450mhz processor, 256 megs of RAM, a Soundblaset Live Value and a Quantum UltraATA, 18GB hard drive. I\'ve had no pops or clicks with memory-intensive sounds like the GigaPiano. My advice for the moment is to go back to Logic 3.6 and then, when you can afford it, upgrade your RAM and see how that goes.
