Editing Electronic keyboard (section)

==Components==
The major components of a typical modern electronic keyboard are:
* '''[[Musical keyboard]]''': Electronic keyboards typically use unweighted keys for portability and affordability. In contrast, digital pianos have [[Action (piano)|weighted or semi-weighted keys]] to replicate the feel of acoustic pianos.
* '''Firmware''': A program (usually embedded in a computer chip) which handles user interaction with controllers such as the musical keyboard, menus, and buttons. These controllers enable the user to select different instrument sounds (e.g., piano, guitar, strings, drum kit), digital effects (reverb, echo, chorus or sustain), and other features (e.g., transposition, accompaniments, sequencer, recording, external media, etc.). The user interface system usually includes an LCD screen that gives the user information about the synthesized sound they have selected like tempo, or  effects that are activated (e.g., reverb) and other features.
* '''Computerized musical arranger''': A software program which produces rhythms and chords by the means of computerized commands, typically MIDI. Electronic hardware can also do this. Most computerized arrangers can play a selection of rhythms (e.g., rock, pop, jazz).
* '''Sound generator''': A [[rompler]], typically contained within an integrated [[Read-only memory]] (ROM), which is capable of accepting [[MIDI]] commands and producing sounds. Electronic keyboard romplers usually incorporate [[sample-based synthesis]], but more advanced keyboards might sometimes feature [[physical modeling synthesis]].
* '''Amplifier and speakers''': an internal audio [[power amplifier]], typically ranging from less than 2.5 to over 30 watts, connected to the sound generator chip. The amplifier is then connected to small, low-powered speakers that reproduce the synthesized sounds so that the listener can hear them. Older and less expensive keyboards may have a single mono speaker. Most keyboards usually have two speakers producing stereo sound, often with [[bass reflex|bass ports]] and [[tweeter]]s for more advanced models.
* '''Power supply''': Keyboards may or may not have an internal power supply system built to the main circuit board, but most modern keyboards are often equipped with an included [[AC adapter]].
* '''[[MIDI]] terminals''': Most keyboards usually incorporate 5-pin MIDI connections for data communication, typically so the keyboard can be connected with either a computer or another electronic musical instrument, such as a [[synthesizer]], a [[drum machine]] or a [[sound module]], allowing it to be used as a [[MIDI controller]]. Not all keyboards have conventional MIDI terminals and connector. The least expensive models may have no MIDI connections. Post-2000s keyboards may have a [[USB-B]] instead, which serve as both input and output in a single connection. Since the 2010s, MIDI in/out terminals are only available in professional-grade keyboards, stage pianos and high-end synthesizers, while low-cost home keyboards, digital pianos, and lower-end synthesizers use USB as the only connection available. 
* '''[[Flash memory]]''': Some electronic keyboards have a small amount of onboard memory (usually in several [[megabyte]]s) for storing data such as recorded songs, MIDI files, and other proprietary files.
* '''External storage device''': Usually available on professional-grade keyboards and synthesizers, this allows the user to store data in externally connected storage media such as [[ROM cartridge]]s, [[floppy disk]]s, [[memory card]]s and [[USB flash drive]]s. Floppy disks and cartridges were obsolete by the early 2000s, with memory cards starting to replace them shortly afterwards. USB storage was popularized by [[Yamaha Corporation|Yamaha]]'s lineup of high-end electronic keyboards in the mid-2000s and has become a standard feature since. Most keyboards since the 2010s use USB storage, with the exception of certain [[Casio]] models, which use [[SD card]]s instead.
* '''[[Music stand]]''': A metal or plastic rack for holding sheet music or music books upright. The music stand is usually removable to facilitate storage and transportation.
* '''Sustain pedal''': If a home keyboard has a [[Sustain pedal|sustain feature]], replicating the similar device used on acoustic pianos, 1/4" jack is provided for this purpose. By comparison, on a digital piano, a sustain pedal is often built into the frame, usually with a proprietary connector. The least expensive home keyboards do not have a sustain function or a sustain pedal jack, which limits their use to early beginners.
