Disklavier-Pro
From Wikipedia, the free encyclopedia
Disklavier-Pro is the "professional" line of Disklavier pianos, which are manufactured by Yamaha Corporation in Japan. They are unique in their ability to accurately reproduce any motion of the keys and pedals (as moved by a human pianist, for example), which it can capture with an array of sensors.
Like with a regular Disklavier, the servo-solenoids actuate the motion of the keys and pedals, but with increased precision, allowing for a truly precise reproduction of the coded performance.
Disklavier uses an extension of the standard MIDI format, known as XP, to encode the performance data. Currently, the latest model of Disklaiver Pro is Mark IV. Disklavier-Pros are used by the Piano-e-competition[1].
They are also the pianos used by Zenph Studios, a company dedicated to making live performances from old piano recordings[2].
