Features: Piano sound quality available only from Yamaha The YDP-103 piano has been enhanced with Yamaha's Advanced Wave Memory (AWM) sampling technology to deliver authentic piano sounds. Advanced Wave Memory is a method that uses digital recordings of acoustic instruments, allowing you to enjoy a superb piano tone within a relatively compact instrument. Thanks to over a century of experience in building acoustic grand pianos, Yamaha is able to incorporate this heritage into its digital instruments. Excellent playability and realistic touch The 88-key Graded Hammer Standard (GHS) keyboard provides a heavier touch in the lower register and a lighter touch in the upper register, simulating the action of hammers inside an acoustic piano. The Graded Hammer Standard is ideal for the aspiring pianist, as practicing on it helps develop proper finger technique for playing on an acoustic piano. Additionally, the matte finish on the black keys reduces slipping during long playing sessions. Pedal adds an extra level of realism The half-damper pedal enables more nuanced and detailed expression while playing, similar to the pedal mechanism on a grand piano. This feature allows for continuously variable sustain lengths, from short to full, depending on how far the sustain pedal is pressed. Quick and easy access to your favorite features via an app The Digital Piano Controller app features an attractive interface optimized for iOS touchscreen devices, adding a whole new level of functionality to the YDP-103. You can turn your iOS device into an easy-to-use control panel, giving you faster access to functions and settings than using the instrument's panel alone. Adjust settings, select voices, and even record performances. Once you've tried it, you'll never want to play without it!
