This is pretty neat, but are they actually playable by a single human pianist? There's parts of the demo video where there are 10 simultaneous notes being played over 4 octaves, which doesn't seem humanly possible. Identifying the notes and chords being played is a big step but you've also got to adapt to the limitations of the instrument and figure out how to simplify it to be playable while retaining the same essence. That's a big part of what makes arrangement difficult.
