I'd love to get some high quality pitch shifting plug that can be automated and sounds really good...any tips? I'd love to put my 192k recordings to a good use :-)
Izotope Radius, specifically made for Logic. One of the best sounding algorithms in my experience.
EDIT: If you are looking at varispeed, Logic's tool does the job - using classic mode
Serato Pitch n Time Pro is considered a very good choice
