If the sound you're talking about is that supersaw lead?  I am pretty sure that it is done with Dune. I don't own it but I know of another track that has that sound. "Rubicon" by 7 Skies and Super8 and Tab. (Extended mix) 7 Skies told me (and my fellow Pyramind classmates) that it was done with Dune. The main lead part after the breakdown. Dune has the ability to create thousands of unison voices. It's very specific to that one synth. It's on sale until Jan 10th too.
Hope that helps
