Yeah, that's pretty small, wow... I guess it's more important to have tons
of RAM if your processing large audio files a lot. But recording shouldn't
as memory intensive.

I use puredyne a bit too. It's nice to have PD with Dyne! ;-)

Yes, of course -- good point. I'm mostly just getting my number from the
cats on debian-multimedia, demudi, and 64studio mailing lists, who discuss
the realtime patches by Ingo Molnar, et cetera. Is the kernel for Dyne II
pretty close to vanilla, or is it patched?
