BS. The piano is one giant trigger pad and the notes play in a pre-programed sequence regardless of where the instrument is struck.


You are right. He is clearly not hitting the corresponding keys. Its a MIDI sequence.

Years ago a friend of mine was sure that you could produce a midi sequence from music audio. I was certain you could not because (similar to what Ant says) you can use analysis to extract frequency information (FFTs, for example), but you cannot extract waveforms of indiviual instruments. One would have to know, at the minimum, all the instruments being played in the audio. You would have to use analysis to determine which instruments are part of the current composite wave form and at what stage of the sound wave each individual instrument was currently at. Seems like a daunting (if possible) task.

Then again, I could be totallyout of my mind about this...
