Another gig of RAM wouldn't hurt either. BiaB loads realtracks from disk to RAM when generating a song. From there on, playback takes place from RAM. I base this statement on monitoring my own hard drive activity.

1 gig of RAM with XP is barely a little more available than what the operating system chews up. Not much left for BiaB sessions. I have an aging hp laptop that runs xp pro and use it during beta testing of BB, just to prove that it will still work on older systems. It has 2 gigs of ram in it. Even then, a long editing session or the loading of realtracks songs back to back can bring the need to stop, close down and reboot the computer in order to get resources back to the point where it will work without stuttering at playback. I've also noticed that use of a hardware MIDI synth and not a software MIDI synth can extend that certain amount of time before resources get used up.

Of course, the newer, more powerful and faster machines here don't have that problem at all. For example, a dual core AMD laptop running Win7 here, 4g ram in it right now, is a noticeable difference in realtracks loading times and performance. And the Intel i7 machine w/Solid State C drive loads and generates so fast by comparison that it often makes me think that something's wrong until I remember which machine I'm using.
