You might want to check the number 3 or 5 on the push; it sounds to me like the reed "bottoms out" when you really push the bellows hard at the ends of some of the phrases and the pitch goes way off tune. I don't know if it will damage the reed or not but it sounds a bit forced at times. Or maybe it's just the little speakers in this laptop! Otherwise I enjoyed the playing and the tone of the accordion.
