Elysium

Elysium is a rich environment for creating layered, evolving, and moving sounds. There really is a wealth of sound creation opportunities to be found here. To be honest, it can sometimes feel a bit overwhelming. However, there are enough options (simple randomization toggles) that can help you create interesting new textures.

(I will, however, say that my experience with support has been not great. After multiple emails and direct messages over a span of months, I never got a single reply from the developers.).
