Mmmm no. I sampled the sounds by myself from the instrumental version of the song. There are a lot of software to extract single notes from chords, search on google and you will find them. Then i made an instrument with ableton live sampler loading my own samples from the song. I use the piano as a midi keyboard to play ableton live on my computer.He bought a soundpack that I'm assuming was the one that Chris's piano is based on and he just transferred the sounds via MIDI/USB to the piano. That or he played it back on a computer.
