Disklavier is the brand name for a group of piano-related products made by Yamaha Corporation. It was introduced in the United States in 1987. The various forms of Disklavier are essentially modern pianos that use electromechanical solenoids and optical sensors connected to LEDs allowing them to play notes and use the pedals independently of any human operator. Most models are based upon real acoustic pianos and have been engineered such that the sensors and electromechanical elements do not interfere with or affect the normal playing of the instrument. They include the ability to store data, including performance data played by a human pianist, and then use that data to replay \/ reproduce the performance. Disklaviers also have inputs for data from MIDI and from several storage devices including floppy disks, CD-ROM, serial cables, and USB.","brand":"Lee Sanders","offers":[{"title":"Default Title","offer_id":47103010668784,"sku":"2940152528213","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940152528213_p0.jpg?v=1764022298","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940152528213","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
