Question

A friend and I have seperate keys for studio one 2 professional. We want to upgrade to professional 3.
Is it possible to buy one upgrade and split the licenses (if there are more than one) to different keys?

Answer 1

Not good news for you and your friend, but the End User License Agreement is pretty clear about it.

5.2 For Licensed Software from the STUDIO ONE product line: 

(a) Licensee is granted one (1) license to install and use the Licensed Software on a single computer at a time.  Licensee may install and use the software on another computer, but the software may not be in use on more than one computer at a time, unless you purchase additional licenses. (..)
