iPhone 4S' Siri Can Now Even Play The Piano! [Video]

It appears the speech controlled assistant featured on Apple's latest iPhone is more than just a pretty voice - apparently, she is even able to play the piano.

Although she/he is not always able to understand what users are saying if they have a British, Scottish, Australian or southern US accent; Siri has no problem interpreting the notes of a piano piece, as Craig Knudsen, creator of SmartKEY for Disklavier, recently demonstrated in this Youtube video.

Moreover, iPhone 4S users don't even need to hack their iPhone to make it play a Yamaha Disklavier like the one in the video (although, the piano itself does cost around £30,000). In order to activate the piano's keys and even move the pedals, Siri needs a WiFi connection and Apple's wireless AirPlay.

The iPhone 4S needs to send a converted song file wirelessly to an Apple Airport Express base station. From there the information is passed to the Yamaha Disklavier reproducing piano; the audio output from the Airport Express is connected to the analogue MIDI inputs of the Disklavier via a standard audio cable.

As the enthusiastic inventor showed, the digital assistant is able to play Rhapsody in Blue, As Time Goes By and Waterfall - although its not clear just how far Siri's repertoire could stretch.

Given that she is still in beta stage, who knows what other surprises Siri may yet have in store.
