Reason+ is a subscription service, and not a specific software that you could upgrade to.
The Reason+ service consists of the following:
- The latest version of the Reason software
- All current Reason Studios Rack Extensions
- Any future upgrades and releases of the Reason software and Reason Studios Rack Extensions during your subscription period
- A stream of inspiring new Sound Packs (containing patches), released every week
- The Reason+ Companion application, used for downloading and managing your Rack Extensions and Sound Packs
If you’re already running Reason/Reason Suite 11.3.8 or later, you can continue to use this with a Reason+ trial or subscription - you only need to install the Companion application.
You could subscribe either monthly at 19.99 Euro/USD (or corresponding local currency), or annually at 199 Euro/USD (or corresponding local currency).
