No loops and no libraries to license. Every element here is modelled from how the real thing makes its sound, placed around the listener at its distance, and it never repeats. Weather puts six of them together as one scene; the others go deeper into one element each. They share one law of distance and one field, so anything you build with them sits together.
Bought one by one: €840. In Worlds: €499. And the free ones, Encode, Downmix, View, Depth and Beacon, work with all of it.
Step up to Total: €400 more, for 20 more plugins. If you already own Worlds, that is all it costs you — what you paid counts in full.
