This is what I'd call a "nice little plugin." It's somewhat limited, with just four patches that you can mix and match, but it can make some nice ambient type sounds, and it has a few nature sounds (birds, rain etc) which are a nice throw-in (minor note, on the bird sounds, it's not just birds; they added some rain or rushing water in the background...odd since they have them as a separate sound you can add. What if you just want birds?). The UI needs a little work..the type is so tiny I can barely read it, likewise with the indicators on the knobs that tell you where you have it turned to (ridiculously tiny dots). But that's also minor. Well worth the download.
I needed this kind of plugin for my projects, le sound create audiorain but is very expensive just for rain, this is free but you can control only volume and pan. But I found this https://www.youtube.com/watch?v=a6pwNi5SuxY&t=11s for NI kontakt sampler, look much better than this frre vst.
