While Splice is primarily a subscription service for samples, they frequently host "Build Challenges" where producers upload the final Cubase project file. Sometimes, these are available for free download.

This project file is designed to sound like a "ready-to-score" film scene. It utilizes stock plugins (so you don't need 3rd party VSTs to open it) but is routed professionally.

Just Producer hosts a section for sharing free project files, including EDM templates and vocal mix templates with pre-configured FX sends.
