MIDI is a technical standard that describes a communications protocol, digital interface, and electrical connectors that connect a wide variety of electronic musical instruments, computers, and related audio devices for playing, editing, and recording music. The specification originates in the paper Universal Synthesizer Interface published by Dave Smith and Chet Wood of Sequential Circuits at the 1981 Audio Engineering Society conference in New York City. A MIDI recording is not an audio signal, as with a sound recording made with a microphone. It is more like a piano roll, indicating the pitch, start time, stop time and other properties of each individual note, rather than the resulting sound.
The Electro-Theremin is an electronic musical instrument developed by trombonist Paul Tanner and amateur inventor Bob Whitsell in the late 1950s to produce a sound to mimic that of the theremin. The instrument features a tone and portamento similar to that of the theremin, but with a different control mechanism. It consisted of a sine wave generator with a knob that controlled the pitch, placed inside a wooden box. The pitch knob was attached to a slider on the outside of the box with some string. The player would move the slider, thus turning the knob to the desired frequency, with the help of markings drawn on the box. This contrasts with the theremin, which a performer plays without touching as two antennae sense the position and movement of the performer's hands.
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument, an electronic derivative of keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a synthesizer with a low-wattage power amplifier and small loudspeakers.
Novation Digital Music Systems Ltd. is a British musical equipment manufacturer, founded in 1992 by Ian Jannaway and Mark Thompson as Novation Electronic Music Systems. Today the company specializes in MIDI controllers with and without keyboards, both analog and virtual analog performance synthesizers, grid-based performance controllers, and audio interfaces. At present, Novation products are primarily manufactured in China.
The keytar is a lightweight synthesizer that is supported by a strap around the neck and shoulders, similar to the way a guitar is supported by a strap. Keytars allow players a greater range of movement onstage, compared to conventional keyboards, which are placed on stationary stands or which are part of heavy, floor-mounted structures. The instrument has a musical keyboard for triggering musical notes and sounds. Various controls are placed on the instrument's "neck", including those for pitch bends, vibrato, portamento, and sustain.
A MIDI controller is any hardware or software that generates and transmits Musical Instrument Digital Interface (MIDI) data to MIDI-enabled devices, typically to trigger sounds and control parameters of an electronic music performance. They most often use a musical keyboard to send data about the pitch of notes to play, although a MIDI controller may trigger lighting and other effects. A wind controller has a sensor that converts breath pressure to volume information and lip pressure to control pitch. Controllers for percussion and stringed instruments exist, as well as specialized and experimental devices. Some MIDI controllers are used in association with specific digital audio workstation software. The original MIDI specification has been extended to include a greater range of control features.
Keyboard expression is the ability of a keyboard musical instrument to change tone or other qualities of the sound in response to velocity, pressure or other variations in how the performer depresses the keys of the musical keyboard. Expression types include:
A MIDI keyboard or controller keyboard is typically a piano-style electronic musical keyboard, often with other buttons, wheels and sliders, used for sending MIDI signals or commands over a USB or MIDI 5-pin cable to other musical devices or computers. MIDI keyboards lacking an onboard sound module cannot produce sounds themselves, however some models of MIDI keyboards contain both a MIDI controller and sound module, allowing them to operate independently. When used as a MIDI controller, MIDI information on keys or buttons the performer has pressed is sent to a receiving device capable of creating sound through modeling synthesis, sample playback, or an analog hardware instrument. The receiving device could be:
The Roland Corporation has manufactured several keytars.
The Continuum Fingerboard or Haken Continuum is a music performance controller and synthesizer developed by Lippold Haken, a professor of Electrical and Computer Engineering at the University of Illinois, and sold by Haken Audio, located in Champaign, Illinois.
EWI is a type of wind controller, an electronic musical instrument. The EWI was invented by Nyle Steiner, his second electronic wind instrument design. Steiner originally brought to market a brass style fingering analogue wind synthesizer instrument known as the EVI in the 1970s. Steiner then went on to develop the EWI which had a unique fingering system closer to the woodwind style. These instrument designs first working models appeared in the 1970s, with the EWI appearing commercially during the early 1980s.
A wind controller, sometimes referred to as a wind synthesizer, is an electronic wind instrument. It is usually a MIDI controller associated with one or more music synthesizers. Wind controllers are most commonly played and fingered like a woodwind instrument, usually the saxophone, with the next most common being brass fingering, particularly the trumpet. Models have been produced that play and finger like other acoustic instruments such as the recorder or the tin whistle. The most common form of wind controller uses electronic sensors to convert fingering, breath pressure, bite pressure, finger pressure, and other gesture or action information into control signals that affect musical sounds. The control signals or MIDI messages generated by the wind controller are used to control internal or external devices such as analog synthesizers or MIDI-compatible synthesizers, synth modules, softsynths, sequencers, or even non-instruments such as lighting systems.
A guitar synthesizer is any one of a number of musical instrument systems that allow a guitarist to access synthesizer capabilities.
The Yamaha WX5, WX11, and WX7 are models of monophonic MIDI wind controller musical instruments manufactured by the Yamaha Corporation that have since been discontinued. The fingering system is based on the saxophone basic fingering. Like a keyboard controller, wind controllers send MIDI note information electronically to an external sound module or tone generator which in turn synthesizes a tremendous variety of musical tones. Unlike a keyboard controller which is usually polyphonic, a wind controller is monophonic. The only limits to the kinds of sounds available are the limitations of the external module/tone generator, not the WX5 itself. A WX5 performer can sound like any melodic instrument: wind, string, percussion, keyboard, or purely electronic, including special sound effects. In addition most tone generators a mix of instruments can be programmed.
CME is the registered trademark of Central Music Company, a musical high-tech company founded in Beijing, China in 1993. Its main focus is consumer and professional digital music production equipment.
The AKAI MPK MINI is a hammer-action, 88-key MIDI controller keyboard released by Akai in November 2009. It is the only MIDI controller in the MPK series to feature hammer-weighted keys.
The Arcadetar is a music performance controller, developed in 2012 by the Italian engineer and composer Andrea Lomuscio. It consists of a 25-note keyboard embedded in a guitar body, and a guitar neck with position and pressure sensors.
ROLI is a London-based music technology company known for its innovative high tech musical instruments, particularly the ROLI Seaboard, a MIDI controller with soft, rubbery keys and continuous, rather than discrete, pitches, and pitch-bending capabilities. ROLI was founded by American-born musician and entrepreneur Roland Lamb in 2009. Its instruments have been used by musicians including Grimes, A. R. Rahman, and Hans Zimmer.
A digital accordion is an electronic musical instrument that uses the control features of a traditional accordion to trigger a digital sound module that produces synthesized or digitally sampled accordion sounds or, in most instruments, a range of non-accordion sounds, such as orchestral instruments, pipe organ, piano, guitar, and so on. Digital accordions typically encode and transmit key presses and other input as Musical Instrument Digital Interface (MIDI) messages. Most digital accordions need to be plugged into a keyboard amplifier or PA system to hear their sounds.
The 12 Step foot controller is a bass pedal-style programmable MIDI controller pedal keyboard made by Keith McMillen Instruments which was released in 2011. It has small, soft, rubbery keys that are played with the feet. As a MIDI controller, it does not make or output any musical sounds by itself; rather, it sends MIDI messages about which notes are played to an external synth module or computer music program running on a laptop or other computer. Each key on the 12 Step senses the velocity, aftertouch pressure, and the amount of tilt the player is applying with her feet. The messages from the player's foot presses can be sent via USB to a computer-based virtual instrument or to a synthesizer or other electronic or digital musical instrument.
