Yamaha Disklavier PRO
On stage is the pinnacle of Yamaha’s piano technology, the Disklavier PRO. It’s a nine-foot concert grand, a regular piano filled with the keys, hammers, strings, and pedals you would expect. It can be played just like any other fine piano. However, it is also packed with a full set of sophisticated electronics: fiber optics, sensors, solenoids, and computers.
The computers read, as input, re-performance data, that is, the precise description of how each key and pedal should be positioned. They decode the numerical values into electrical signals. These electrical signals are, in turn, triggers to the solenoids. Picture a piano key; it’s actually twice as long as what you see in the front. Each key is a long lever; when you press it down in the front, it rises in the back, to toss the hammer up to hit the string. A solenoid is an electrically-driven magnet, one positioned at the back of each key. Its job is to replicate, in inverse, what your finger would have done in pressing the front of key. It requires great speed and precision to reproduce all the subtleties of a skilled pianist.
You may be familiar with a computer music standard called MIDI. The native resolution of a Disklavier PRO far exceeds that of standard MIDI, but they’re also backward-compatible, capable of playing the MIDI files used by regular Disklavier pianos. Zenph’s software packages – HCX, Internet MIDI, and RePerform – enhance the capabilities of every new Disklavier and Disklavier PRO sold by Yamaha.
Tonight’s Disklavier PRO has been graciously furnished for this event by Yamaha Artist Services. Gershwin’s re-performance and Zenph’s HCX software was prepared by Zenph team members Phil Amalong and Anatoly Larkin.
