Holy shit CPU friendly my ass.. I just tried the demo of this bitch... with one instance loaded it doesn't take up but 1% cpu.
As soon as I hit play on a little 1bar sequence - 50%!!!!!!

This is on an 800MHz Powerbook G4

Yikes. Even my Korg plugins don't do that!

Gonna have to see how bad it rapes my 1.7GHz PC at home.
