I have practiced using this alot lately!! Its pretty awesome. Just a thought tho. How come when Im playing a song and I put my phone upside down and it makes this wierd.... thing I cant explain. Its cool for some songs tho and dont change it I like it! Its like this pond ripple affect but instead of the visual effect on the antenna thing, its a sound effect. Like the volume are continously going down and up in a pattern. Great app tho. I have only experienced one problem with the recording once. I recorded and recorded the high note [where you dont touch any hole( or what I used is the button on the top left on touch mode )] And speaking of which, Im trying to put Touch Mode off and it says off and I still cant blow on it
