Amazing

I feel like not a lot of people know how to properly use autotune. I use this plugin for a live setup mostly. It sounds fantastic, though i mainly use waves tune for recording ( for the sake of quickness), it cant be used live like this can. The humanize knob helps and is a great feature. Of course, it's important to know how to properly set up autotune for live use, unless you want to sound like t-pain and constantly warble.

Great pitch correction software

I actually have auto tune 5 I think it is, but they are pretty much the same and if this is an upgrade then even better! Works very well when trying to correct a few 'pitchy' notes. You can move the note quite a bit without getting those digital artifacts which drive me crazy. I haven't tried the auto feature yet, but the graphic mode is great! can be used on vocals, guitars, bass or whatever.

Nice upgrade, EXCEPT....

As a longtime user of Autotune, this latest version offers some significant new features that both streamline your workflow and improve the quality of tuning. This and more you can read in the listed features. HOWEVER, what you won't read is the fact that Evo introduces significant delay (1000+ samples) on the track that its instantiated on. For Pro Tools M-Powered and LE users (i.e. no ADC), this is a serious annoyance that did not exist in previous versions of the plug-in. There are viable workarounds, but it's a hassle; and, as I said, nothing was mentioned on Antares' site, so it was an unpleasant surprise. Just the same, it's a significant enough upgrade that I'm considering keeping it (vs. getting a refund). If you don't mind this new unpleasant issue, it's worth upgrading to.
