Izotope has a sale for August for half of Radius for Logic - $199 instead of $399. Its supposedly a better pitch shifting algorithm that works only in Logic. I got a code in an email from them, but I am not sure i can share it. Try contacting them. I have never used Radius myself, but perhaps someone else here can offer their experiences.
