Thats great, how do you happen to have both? Hey can you make two more tests? One thing is to slow down a pop piece in an extreme way - say a 6th or even octave. And the other thing, is can you slow down a drum loop - supposedly Izotope has transient features which might allow it hold good transients even as it slows down. But tests would help demonstrate that.
To help people compare the two, I've pitch-shifted a 30-second
cello/piano duet up 400 cents using Logic's own algorithm,
Pitch'nTime's and Radius'.
