Combine Any Of These Libraries With Krotos Plugins

These libraries come with integration for Weaponiser or Reformer Pro, but what does this mean?

  1. When you buy a Krotos library, you get both the standalone sound files AND a library installer program.
  2. All you have to do is run this installer. When installation is finished, the library automatically appears in either Weaponiser’s presets or Reformer Pro’s library, depending on which plugin the library is for.

This saves you the time and effort of having to create presets out of the sound files in the libraries – they are added, indexed and ready to go! The combination of these plugins and our libraries provides a powerful, fast and effortless workflow for any of your sound design projects, whether you work in film, TV, games, podcasts or music.
