After all those numerous things we have seen Siri do in the past, Apple's intelligent personal assistant has added another feather to its cap, playing no less than a Yamaha Disklavier piano and creating a tune that is soothing to your ears.
For those unaware, a Disklavier is effectively a modern day piano that uses electromechanical solenoids and optical sensors connected to LEDs which allow them to play notes and use the piano pedals without the need for a human operator.
The engineers at Yamaha have used Apple's arsenal consisting of an iPhone 4S, Siri technology, and an Apple Airport Express and combined it with one of their own Disklavier pianos to create possibly one of the coolest choooons anyone can muster.
The playback is achieved by taking a standard MIDI song file and converting it to a recognized audio file, making sure that all of the MIDI data is preserved in the process. The outputted audio file is then sent wirelessly from the iPhone 4S using Airplay technology to the Airport Express.
The next step is where the magic happens. The audio output of the Airport Express is connected to the analog MIDI inputs of the Disklavier piano using an everyday standard audio cable. By activating Siri and requesting a song to be played the whole process is initiated, making the Disklavier’s keys and pedals begin movement, recreating the chosen song seamlessly.
