The Disklavier Pro is the flagship of Yamaha’s highly acclaimed series of Disklavier pianos which
incorporates newly developed technologies that enable dynamic, high-precision recording and playback of an
unprecedented level. Combining innovative high-performance technology with the renowned Yamaha acoustic
grand piano, you can be assured of the ultimate reproduction of even the most intricate and demanding
performance.
Faithful playback using servo control technology
The heart of the Disklavier Pro’s high-performance capability lies in Yamaha’s exclusive servo control
system which uses a combination of high-power solenoids and ultra-sensitive sensors. Precision control
of this advanced system is realized by a new, exclusively developed processing unit consisting of eight
LSIs. The result is accurate playback of the widest dynamic range ever, from the faintest pianissimo to
the strongest fortissimo. Even the playback of silent notes used to add harmonics to other notes is
possible, giving the Disklavier Pro the ability to play back virtually any performance exactly the way it
is played.
True-to-original recording
High-precision recording is realized by a unique dual sensing system where newly developed optical
sensors monitor every movement of the keys along with the speed of each hammer stroke. In Enhanced
mode, key sensors not only read how softly or firmly a key is pressed, but also the dampening speed of
the notes when the key is released, thus making it possible to precisely reproduce light staccatos and
smooth legatos. Even songs in which release speed is not recorded can be played back at a natural
speed. Moreover, with the Disklavier Pro’s extended MIDI data fomiat (XP mode), optical sensors
monitor key movement and assign MIDI control parameters to the data, enabling the Disklavier Pro to
record and play back even the finest differences in keyboard touch from delicate half key strokes to
deep, fully-pressed strokes.
The Disklavier Pro’s impressive recording and playback capability ensures perfect capture of all the
subleties of a pianist’s performance.
HIgh-precIslon pedal drive
The pedals are also controlled using optical sensors and digital servo technology with a special
dedicated 32-bit processor, enabling fine processing of even the smallest pedal movement.
Built-In calibration system
To maintain optimum playback and recording conditions, the Disklavier Pro has a versatile calibration
system which fully supports servo technology to calibrate the solenoids and sensors from every
checkpoint. This ensures standardization of recorded data and compensates for any unevenness
throughout the 88 keys to guarantee ultimate performance every time.
