Other Features
Most digital pianos implement a variety of features not found on a traditional piano.
Digital pianos usually offer a MIDI connection, allowing them to control or be controlled by other electronic instruments and sequencers. They may also have a disk drive or other external media slot to load MIDI data, which the piano can play automatically, allowing it to function as a player piano.
Some have a built-in sequencer to aid in composition.
It may have illuminated keys so that a beginner can learn a piece by playing keys that are lit.
Some can transpose music as it is played, allowing the pianist to play in a familiar key while the piano renders it in another.
An acoustic piano produces reverberation in its soundboard and in the room where it is played. Digital pianos often have a feature to electronically simulate reverberation as well. Other digital pianos may have additional reverberation options such as a "stage simulation." Some also have chorus, tremolo, and phaser effects.
Some offer additional voices: String instrument, harpsichord, organs, clavichord, etc.
Since the inception of the MIDI interface standard in the early 1980s, most digital pianos can be connected to a computer. With appropriate software, the computer can handle sound generation, mixing of tracks, music notation, musical instruction, and other music composition tasks.

Famous quotes containing the word features:
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (1817–1862)
