The Bone-flute is lovingly programmed to provide a playing experience markedly superior to anything else available in the Paleolithic and even well into the Neolithic ages.
(Truth in advertising disclaimer: okay, I made up the bit about the 12,000 years and the Megatherium; if you really need it to be, like, real - well maybe you shouldn't be playing a sampler, but hiring a Megatherium-thighbone-flute player; don't stint, Megatherium-thighbone-flute players need to eat too!).
