Cubase 6 & Cubase Elements

Hi to all. I’m new with this software and I saw that there’s three Cubase’s versions. I know that Cubase Artist is lower than Cubase but, for what is Cubase Elements? It’s an upgrade or something like that?

Elements is the entry level product in the Cubase range (lite version).
Check the feature comparison for detailed info between versions.

Thank you!
