Editing MIDI controller (section)

==Features==
MIDI controllers usually do not create or produce musical sounds by themselves. MIDI controllers typically have some type of interface that the performer presses, strikes, blows or touches. This action generates MIDI data (e.g. notes played and their intensity), which can then be transmitted to a MIDI-compatible [[sound module]] or [[synthesizer]] using a MIDI cable. The sound module or synthesizer in turn produces a sound that is amplified through a [[loudspeaker]].

The most commonly used MIDI controller is the electronic [[musical keyboard]] MIDI controller. When the keys are played, the MIDI controller sends MIDI data about the pitch of the note, how hard the note was played and its duration. Other common MIDI controllers are [[wind controller]]s, which a musician blows into and presses keys to transmit MIDI data, and [[electronic drums]].

The MIDI controller can be populated with any number of sliders, knobs, buttons, pedals and other sensors, and may or may not include a piano keyboard. Many [[audio control surface]]s are MIDI-based and so are essentially MIDI controllers.

While the most common use of MIDI controllers is to trigger musical sounds and play musical instruments, MIDI controllers are also used to control other MIDI-compatible devices, such as stage lights, digital [[audio mixer]]s and complex guitar [[effects unit]]s.
