In this TED talk, Zenph’s John Q. Walker demonstrates how recordings can be analyzed for precise keystrokes and pedal motions, then played back on computer-controlled grand pianos.

Controversial but interesting techology – is it really a Glenn Gould performance anymore, or just a way to generate a new recording with a new copyright?
