Izotope's Nectar 3 Pitch for solos

Hi pals

I just found, by accident, that Nectar 3 Pitch works very well to adjust guitar solo notes

Just route the guitar (or other instrument) plugin to Nectar, drop Pitch, ask it to recognize the scale, and bingo!

Have you ever noticed that?

And in case, do you think that Nectar 4 may be better in this task?
