Scale correction

What I would like to be able to do is detailed on the video below. The basic idea is for me to play freely on the keyboard and have cubase adjust to fit whatever scale I choose.

Perhaps that is not available on Elements. What would I need to upgrade to to have this feature?
Is there perhaps another way to do this in Cubase Elements?
