Tony,
The Project and Mastering Suite of Studio One is ONLY a feature of Studio One Professional. This has been the case for every version of Studio One, since it was launched.
The specific features for each version of Studio One 3 can be found here:

The only way to get this Project and Mastering feature would be to upgrade to the Professional version of Studio One.
