Raspberry Pi transforms upright piano into a retro loop player
Upright piano's don't exactly scream "high-tech," since everyone's weird aunt has one. A pair of hackers from a company called MajorMega may change your mind, however as they've modified one to give you and your friends a fun way to create multi-part compositions. The "Quaver" upright piano is equipped with a Raspberry pie board that makes it act like a 4-track recorder and loop sampler. All you have to do is sit down, punch the big "record" button and bang out your part of the song. When you hit the button again, the piano will instantly play back your creation in a loop.
