Yamaha P-255 digital piano revealed

Yamaha has updated its Yamaha P Series of digital pianos with the P-255. Yamaha suggests it has a more authentic piano sound and feel than before. It’s highly portable and can also be used with matching stand and three-pedal accessory, making it great for both on-the-move and in the home. In addition, an optional iPad app can be used to graphically alter the instrument’s settings.

The P-255 has three functions not found together on any other P Series instrument before:

Yamaha P-255
Yamaha P-255
  • Key-off samples: This feature reproduces the slight change in sound at the instant you remove your fingers from the keys. What’s more, different key-off sounds are produced for staccato and legato playing.
  • Sustain sampling: The resonance of the soundboard and strings heard when the damper pedal is used has been sampled in order to recreate this acoustic effect. The P-255 responds to how deep you depress the pedal.
  • String resonance: When the hammer of a grand piano strikes its string, the other strings will also resonate. The P-255 can reproduce this effect using its String Resonance feature.

Additionally, the P-255 uses the Pure CF Sound Engine for its samples.

The instrument has synthetic ivory key tops for a more authentic playing experience and with moisture absorption properties.

Its built-in circular speakers vibrate in a natural manner to produce a well-balanced tone. In particular, lower notes are richer than digital pianos featuring oval speakers. The P-255 also features tweeters, for improving higher note reproduction, and dual 15W amplifiers.

The Sound Boost button can be used to increase the volume and presence of the sound. Coupled with this, three EQ sliders allow more fine-tuning of different frequency ranges.

The P-255 also features rhythm tracks (ten in total), a range of other non-piano sounds including organs, a string section, basses and a wide variety of other instruments, variable touch response setting, direct-to-USB audio recording, and 256 note polyphony.

The free P-255 Controller App for iPhone or iPad lets you can control a wide range functions with an easy-to-use, touch-screen interface. This visual approach to configuring the P-255 makes it easy to try out functions that you may not have considered using before. Graphically choose which Voices to layer, adjust the split point, manage songs you record to a USB device and more, all with the touch of a finger. You can also use the app to store your favorite settings and recall them instantly whenever needed. Explore the settings and sounds of the P-255 even before yours arrives at home.
