Re: (no subject)

I'm working on getting csound to compile under 64 bit for a line of new 64
bit linux laptops we're building for cosmoseng.com, right now just running
cosund32 in emulation I still get a big performance boost with the
athalon64, but once I've got a native 64 bit version of csound running it
should perform like a monster.
