I would like an app that is like the sound mixer that's on soundsleeping.com : their "Drum Sleep Aid / Relaxation Tool". Actually, I'd like to be able to use that one on my Pixi. Is this possible? Can some one do this and let me know? I am really fond of their "creek", which I mix in some "crickets" and "flute song" at lower levels. It calms my day and eases my moods.
