The more random-sounding an effect the better but for some the loop is far too short and it becomes monotonous rather than soothing. Sound quality is quite good for the most part, but perhaps cutting down the sheer quantity and, quite frankly, duplication of sounds would allow for longer samples than only a few seconds. Perhaps there will be improvement when it hits 2.0?
