Installation

Automatic (Recommended)

1. Download the latest REAmo-vX.X.zip from Releases
2. Extract the ZIP file
3. In REAPER, run Actions > ReaScript: Run ReaScript... (Action ID: 41060)
4. Select Install_REAmo.lua from the extracted folder
5. Restart REAPER
6. (Optional) Preferences > Media — uncheck Set media items offline when application is not active. If enabled, REAPER takes media offline when you switch to another app, which prevents waveforms from loading on your device.
