iPhone 4S Siri has been used to control a house temperature and more. And now guys at Yamaha have managed to get Siri to play a piano, using the Yamaha Disklavier reproducing piano.
A video is included below showing how the Yamaha guy speaks to Siri to get it to play the piano. Explanation is also included if you’re curious how they managed to do that.
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.
