the PianoHack

This product will let anybody who already has a piano midi controller play through chord progressions while still playing chords on the piano without learning any fingerings of traditional piano chords. (Picture does not do it just as the product is not meant to be seen, the magic is all in my coding of this product.)

Anyone can start making music and playing piano chords without learning music theory or practicing chords shapes. No wrong notes. The player uses his own dynamics on the keyboard and chord choices.
