PSA: You can share the User Library with Ableton

  1. Cut and Paste ~/Documents/Renoise/User Library to ~/Music/User Library
  2. Symlink
    Win
    mklink /D "C:\Users\<YourUsername>\Documents\Renoise\User Library" "C:\Users\<YourUsername>\Music\User Library"
    Mac
    ln -s ~/Music/User\ Library ~/Documents/Renoise/User\ Library
  3. Set location in Ableton

    The original location /Music/Ableton/User Library remains if you need to transfer samples etc as only the structure is replicated, gather what you need and and delete it afterwards

The resulting file structure is very interesting and useful as they have no folders with same name, like they were made for each other!
