Its PortAudio running through CoreAudio. If you use Jack on OS X,
you'll see your % usage decrease
significantly. I can easily cut my CPU usage in half by using Jack on
OS X. I've also seen notable decreases when using cycling74's
On a similar note, if you happen to be using a firewire audio
interface, you're cpu usage will be even higher!
ps: sorry if ppl are getting reposts, I'm having severe mail issues.
