Pianissimo: Piano learning, reimagined

什么是 Pianissimo: Piano learning, reimagined？

It’s a small LED screen I built to help people learn and practice piano in a more intuitive way. It's inspired in Guitar hero, but for piano. Pianissimo sits on top of any keyboard, and receives MIDI files via bluetooth, decode them and transform the file into a series of falling lights that indicate the user when to press each key on the keyboard.
