- Download the installer for your platform from your account at restemapp.com (or the trial from the product page).
- Run it. On macOS you get AU, VST3, VST, AAX and the standalone app; on Windows VST3, VST, AAX and the standalone.
- Open ReStem (plugin or standalone) and log in with your restemapp.com username and password — that’s the activation.
- No internet on the studio machine? Post in Help & Support and we’ll walk you through it.
Common first-run notes
- Pro Tools: use the AAX; ReStem appears under Other.
- Logic: ReStem runs as a regular AU insert.
- REAPER: for the deepest integration, add ReStem as a track insert — it also supports ARA2 there.
- ReStem 2 Core is standalone-only by design — the plugin formats are a Pro feature.
