FX Chains

Pre-configured plugin combinations for common workflows.

How to install FX Chains

Copy the .RfxChain files to your Reaper FXChains folder:

Windows
C:/Users/[Username]/AppData/Roaming/REAPER/FXChains/
macOS
~/Library/Application Support/REAPER/FXChains/
Linux
~/.config/REAPER/FXChains/

In Reaper: open the FX window, navigate to the FX Chains category in the left panel. Select your chain — all plugins load automatically in the correct order.

⚠️ Important: For FX Chains to load correctly, the null-jsfx plugins must be installed in the Effects folder as a subfolder (not scattered files). Path example: Effects/null-jsfx/*.jsfx
