A joke Okay, so you pay 5$ for this "feature". And what for, exactly? This "upright piano" sounds so horribly artificial that it doesn't even sound like a piano anymore. Please use a higher quality library / synthesizer or ask for less. This is never worth 5$ Edit: And yes, I have used very high quality headphones to listen to this (even went to borrow from a friend who owns a pair worth 400$). I play piano myself, but this sounds like what I would expect from a cheap electric piano.
