Wonderful
Great sound, very interesting tone control --- and best of all, its a free app that doesnt visually YAMMER at you to buy, try or rate! Its ON when you open it (no menu or promo screens to leaf through), and the ads are so discreet they make you curious rather than bored or annoyed.
Lovely, lovely bongs. It can indeed sound like a marimba, or a steel drum. I love this app, and I hope all its virtues dont get "improved" away.
