The most common of these are the piano, organ, and various electronic keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas, which are struck idiophones operated by a keyboard, and carillons, which are usually housed in bell towers or belfries of churches or municipal buildings.

One of Shawn Wasabi's equipment is the DJ TechTools Midi Fighter 64, a custom 64-button MIDI controller. [7] The Midi Fighter line of controllers is notable for using Japanese Sanwa arcade buttons rather than the rubber pads traditionally used on MPC-style MIDI controllers. [7] Initially, the Midi Fighter only came in 16-button variations. [7]
A MIDI keyboard or controller keyboard is typically a piano-style electronic musical keyboard, often with other buttons, wheels and sliders, used as a MIDI controller for sending Musical Instrument Digital Interface commands over a USB or MIDI 5-pin cable to other musical devices or computers.
A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys—sufficient for a full five octaves of range (61 notes).
Most electronic keyboards use spring-loaded keys that make some kinds of playing techniques, such as backhanded sweeps, impossible, but make the keyboards lighter and easier to transport. Players accustomed to acoustic piano keys may find non-weighted spring-action keyboards uncomfortable and difficult to play effectively.
The keyboard sends the key code to the keyboard driver running in the main computer; if the main computer is operating, it commands the light to turn on. All the other indicator lights work in a similar way. The keyboard driver also tracks the shift, alt and control state of the keyboard.
A musical keyboard is the set of adjacent depressible levers or keys on a musical instrument. Keyboards typically contain keys for playing the twelve notes of the Western musical scale, with a combination of larger, longer keys and smaller, shorter keys that repeats at the interval of an octave.
An isomorphic keyboard is a musical input device consisting of a two-dimensional grid of note-controlling elements (such as buttons or keys) on which any given sequence and/or combination of musical intervals has the "same shape" on the keyboard wherever it occurs – within a key, across keys, across octaves, and across tunings.
