A workaround for the “ItemFX Buffer Click bug” in Reaper

If you use ItemFX in Reaper I’m sure you come across “ItemFX buffer click”. Without going into too much detail the last buffer risk being left in memory and being released as the plugin wakes up the next time you play the item, creating a click that is very annoying. This applies to random developer’s plugins too, not just my plugins (Waves plugins amongst others). If you all of a sudden have a click at the beginning of an item and don’t get where it comes from you probably have this buffer issue with some plugin in the chain.

To use this in Reaper:

  • Download the ‘100ms fade in.lua’ file below
  • Open Reaper
  • Go to the ‘Actions’ menu and click ‘Show action list’
  • Click ‘New action’ and choose ‘Load ReaScript’
  • Find and load the downloaded Lua file in the file dialog that shows up
  • If you want to assign a key shortcut; Select the newly loaded script in the list and hit ‘Add…’ in the ‘Shortcut for selected action’ area down to the left
  • Hit the key that you like to use as your shortcut
  • Close the ‘Actions’ window 
  • Done

To use it you just select the item where you want to apply the script and hit your selected shortcut key.

Thanks to Odedd, ErBird, Ess7, Cohler, and OpenAI for the snippets of code and ideas that I used to create this script.
