Siri’s been hacked to remotely start a car and even change channels on a TV set, though this is likely the first time iPhone 4S’ digital assistant’ hasbeen made to “play” an instrument. Using an AirPort Express and some special MIDI files, this Siri hack is able to make the not-so-cheap Yamaha Disklavier piano play requested songs. Here’s how the setup works according to The Loop:
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.
For those fortunately enough to own a Disklavier, there’s even an iOS app – Disklavier Controller - that lets you perform similar functions like song selection and playback. Of course, this is no where near as cool as asking Siri to do all the hard work for you.
