We’ve all seen some cool things that Siri can do, but this has to be the best so far. The guys at Yamaha got Siri to play piano.

Here’s how my friend at Yamaha explained it to me:

Take a standard MIDI songfile and convert it to an audio file (while maintaining the MIDI data). The songfile is then sent wirelessly via WiFi to an Apple Airport Express (which is mounted underneath a Yamaha Disklavier reproducing piano. The audio output of the Airport Express is then connected to the analog MIDI inputs of the Disklavier, using a standard audio cable.Then, you simply ask Siri to play your favorite song from your iTunes library, and Siri responds immediately, by making the Disklavier’s keys and pedal move up and down, recreating the performance, including full orchestration.
