Antares Auto Tune for Pro Tools

Hey,
At the risk of sounding like an idiot I will ask this question. I am using protools for recording and am in the mixing stages. I am interest in downloading the trial of Antares auto tune plug in. What format do I need to get? TDM, RTAS,MAS, VST? Thanks in advance.

Figured it out

I actually contacted tech support and amazingly they responded within a few minutes. It needs to be the RTAS format for Pro Tools. Check out what I've got so far www.acoustidesign.com/superlatives.html
