Cubase 7 Elements pitch shift?


This is my first time here in the forum. I am a vocal teacher and i’m trying out the Cubase 7 Elements version to evaluate if it has all the features i need for my classes, one of the most important ones being the Pitch Shift, so i can change the key for some songs. In the specs table it has a yellow check mark (real time). The problem is i can’t find the tool in the trial version or any explanation for the yellow check mark. Does anyone know how it works, if it works at all? Or is it some sort of add on that i will have to buy separate from the license? I find it strange that Steinberg doesn’t explain this anywhere…
Thanks in advance!

Cheers and happy new year!
