Apple Logic Pro /LogicExpress Discussion

Both Pitch 'n Time and Izoptrope's new Radius are half price right now 
@ $199.

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'.  I've uploaded them to the FILES section of 
the group website in a zipped file named "IzotopeVSerato.zip ".  The 
zip file contains the three pitch-shifted samples plus the original, in 
  A min.

Logic's native algorithm sucks big time, but I can't hear much 
difference between the two 3rd party versions.  Can any of you?  I'll 
try slowing down or pitching down with some different material to see 
if that can differentiate the two.  I'm interested in others' opinions, 
as I probably will end up getting one or the other.

Thanks,

Gregory
