This App is unique because you select the sounds and there are many varied sounds available. Those sounds may be rearranged and come and go in a way that keeps things fresh but they are always your sounds. And, presumably, you made those selections because, that’s what you needed to hear (there’s a handy undo button!). Hearing one’s sounds cycle around can become immersive and emotional. Confining the soundscape to the users selections is what sets this app apart and makes it, by far, one of the “best in it’s class”.
You can make it spacey or super dense and exciting.
In my experience, similar apps, including those produced by artists mentioned in the app description, are cool in an of themselves, but, for me don’t have the emotional resonance of Cosm’s. This is because they insert their own sounds into the soundscape. Sometimes that can be interesting, but too often I find it intrusive. I don’t use this type of app to jam with an algorithm, I want to explore my own space.
