Is there/what is the upgrade cost from Sonar X2 Essentials to Sonar X2 Studio?
Is it simply the difference in price? Or is it cheaper/more expensive or something.
ALso, is it avilable for the boxed (essentials) product, and can the upgrade (studio) be bought as a boxed product rather than just a download for the same price?

if you want the box of DVD's, that's an extra $30.

it's all there in the e-store.
