Integrating state-of-the-art technology into top-of-the-line Yamaha grands, Disklavier Pro™ Series grand pianos provide a uniquely effective, high-performance solution for studios, institutions and today's most discerning musicians. Their servo-controlled drive system and other advanced components record and reproduce acoustic piano performance with unprecedented power, precision and control.

Additional features – including Silent functions, XG instrumental tone generation, MIDI and PC connections, and a new control unit with CD drive, expanded memory and more – let you take full advantage of a whole new era of musical opportunities. Engineered to the exacting standards of professional music production, the New Disklavier Pro Series offers incomparable versatility and superior performance for applications from recording, collaboration and academic study to film scoring, music broadcasting and multi-media/Internet content development – as well as an unparalleled source of entertainment and enjoyment for those with the most highly developed musical sensitivities.

In addition to offering all the traditional attributes of Yamaha acoustic pianos, Disklavier pianos can also play themselves, providing exciting musical entertainment at any time, with or without a pianist.

The Disklavier can reproduce live piano concerts by many of the world's favorite artists, exactly as they were played, complete with the visual drama of key and pedal movement. It's like having the most renowned pianists performing just for you, 'live' in your own home. It can also recreate remarkable realistic instrumental sounds, allowing you to enjoy jazz combos, popular groups, chamber music and more.

Ideal for relaxing or entertaining at home, the Disklavier also provides an exciting attraction for hotels, restaurants and other establishments. Versatile programming options, remote control and a full complement of external connections make it easy to host, customize and automate Disklavier performance, and treat guests to a memorable musical experience.

Combining the tone and touch of a Yamaha piano with an astonishing range of digitally enhanced capabilities, the Disklavier piano provides a truly unparalleled musical entertainment system for any home or business.

Disklavier Pro Series grand pianos set the highest standards of accuracy in acoustic reproduction. Using feedback between sensor and drive system components under the command of specially developed LSI microprocessors, the servo control system continuously monitors the movement of each key, precisely recreating every detail of the original performance. High-speed processing and an internal compensation system virtually eliminate any speed or timing deviations, while built-in calibration ensures consistently perfect playback.

Special high-powered solenoids respond instantly and accurately to playback signals generated by the high-sensitivity recording sensors, reproducing a wider range of dynamic control than has ever been possible before. From the most delicate pianissimo to thundering fortissimo, the Disklavier Pro accurately records and recreates the full spectrum of musical expression.

A sophisticated system of optical sensors records every motion of the keys with meticulous precision – even keys touched only for harmonic value or to ease a fingering transition, without sounding the strings. Continuous-position key motion sensors register key speed, depth and release speed, while hammer sensors register the speed of each hammer blow. Together, they form the most accurate system available for reproducing keyboard performance, all without any mechanical interference with keyboard touch or response. A special dual-position shutter allows hammer sensors to deliver optimal performance in both normal and Silent modes.

Sensors on the Disklavier Pro Series grands register not only the down stroke but the release speed of the keys – a major advance in Disklavier technology. This generates the data required for accurate damper control, reproducing the delicate nuances of staccato and legato phrasing. Even conventional software, recorded without this additional key-release data, sounds better on the Disklavier Pro Series pianos, as these instruments determine and recreate the natural release speed for each keystroke.

Sustain and shift pedals are equipped with continuous-position digital optical sensors and servo-controlled drive units, controlled by their own dedicated processor. These support precise levels of incremental movement to faithfully reproduce every pedaling action of the recording or performing artist.

The new Pro Series grands include CD and floppy disk drives. They're compatible with a wide range of music software and can reproduce both audio and MIDI tracks in conjunction with the piano. Internal memory has increased to 16 MB, in 16 linkable memory disks. A clock/timer lets you program automatic playback and time-stamp MIDI data for PC editing. Digital instrumentation now offers a far wider range of selectable voices.

The new Disklavier Pro Series full-function models now play compact disc software in addition to floppy disks, further expanding your options for musical entertainment. This enables your Disklavier piano to reproduce high-fidelity vocal and instrumental audio tracks, so you can experience the sound of your favorite groups – complete with vocalists and instrumental soloists – enhanced by the live concert presence of Disklavier acoustic piano playback. With a variety of audio/MIDI CD software already available, and others including the exciting new Yamaha PianoSoft PlusAudio™ titles in development or production, your Disklavier can offer you a wider variety of prerecorded concerts than ever before – all with the convenience, durability and ease of use of conventional audio CDs.

To achieve its superior recording and playback performance, the Disklavier Pro generates extra MIDI data to accommodate precision parameters. All essential data such as hammer speed, key release speed and pedaling is recorded and reproduced within the standard MIDI format, enabling full compatibility with other MIDI devices. For recording piano performances with even more subtlety and detail, you can select the expanded Yamaha XP MIDI format. This utilizes general-purpose controller numbers in the MIDI specification to record additional performance data including key speed and stroke depth, for recordings of enhanced sensitivity and precision. Multi-mode flexibility allows the Disklavier Pro to interact smoothly with existing MIDI configurations and reproduce data generated in either XP or enhanced mode, with automatic selection of the appropriate playback format.

The Yamaha Grand Silent System provides additional versatility. With the touch of a button, you can prevent the hammers from striking the strings, while generating superb real-time digital piano tones – so true to life that they even recreate the harmonic resonance resulting from incremental use of the sustain pedal. The Silent System is also ideal for multi-track recording, allowing you to record orchestral tracks from the piano keyboard without sounding the piano. An exclusive Quick Escape™ action mechanism and dual-mode sensors automatically compensate for hammer stroke variations, maintaining natural touch and response in both Silent and conventional modes.

An integrated Yamaha XG tone module can generate 697 digital voices, 491 of which are now selectable at the control panel. This makes it easy to record other instrumental sounds in addition to the piano, or reproduce fully orchestrated piano/ensemble concerts through headphones or your own amplified speakers.

For anyone who's ever dreamed of playing the piano, but thought they didn't have time to learn, the new Disklavier grands can make your dream come true, without lessons, and even if you've never touched a keyboard or read a note of music in your life!

With the new SmartKey feature, it's easy. Just follow along as SmartKey partially depresses the next note to play. Within minutes, you'll be playing entire songs, complete with virtuoso harmonies and arpeggios, played to your lead by the Disklavier itself.

CueTime™, another exciting new integrated feature, offers sophisticated auto-accompaniment. You simply play the piano part, and the digital orchestra 'follows your cue,' matching your pace and enhancing your melody with professional-sounding instrumentation.

The responsive sensitivity of the grand piano action makes this an incomparable MIDI controller – far superior to other digital keyboards – as well as a superb acoustic instrument. Silent System technology lets you 'turn off the piano' when playing on connected equipment. You can even cancel the movement of keys or pedals during playback, to facilitate overdubbing or collaborative performance.

Terminals, including MIDI In/Out, AUX In/Out and a pair of headphone jacks, let you link with external devices. And the direct computer interface gives you easy access to PC software, peripherals and the Internet.

In describing the advanced features of the Disklavier Pro, it's easy to overlook the remarkable capabilities of 'standard' Disklavier pianos. Keyboard-direct recording onto standard floppy disks or internal memory disks, for example. 'Live' acoustic playback complete with key and pedal movement, plus tempo, volume and transposition controls. Separate left/right recording and independent playback. Repeat, search, utility functions and more. These features are all available on the Disklavier Pro Series as well.

A special dual-position shutter allows hammer sensors to deliver optimal performance in both normal and Silent modes.

The DS4APRO grand piano is an instrument of rare perfection, handcrafted from the very finest materials to the highest professional standards in the Yamaha concert grand workshop.

The Yamaha Servicebond Assurance Program is provided to the customer, without additional charge, 3-8 months after delivery of their piano. This service is a thorough check up and adjustment procedure to "rejuvenate" a piano after play-in and acclimation to its new environment. After 3-8 months or so of settling and becoming acclimatized, the piano will receive the benefit of a service visit to return it to the conditions specified by the manufacturer.
