In most cases where you purchased an interface or boxed version of StudioOne, the Studio One registration key and online activation code is found on the inside of the trifold CD sleeve.
With a digital purchase from our web store or other third party affiliates web store, that code will likely come in an email to the email on file for the retailer that you purchased from.
* Some digital purchases of StudioOne and hardware registrations, automatically register StudioOne to your user account.
TIP: Always log out of your user account, then log back in when you purchase through our web store or have registered a bundled hardware product key in your account to see if the software was registered to your account automatically.
