An electronic musical instrument or electrophone is a musical instrument that produces sound using electronic circuitry. Such an instrument sounds by outputting an electrical, electronic or digital audio signal that ultimately is plugged into a power amplifier which drives a loudspeaker, creating the sound heard by the performer and listener.
Composite video is an analog video signal format that carries standard-definition video as a single channel. Video information is encoded on one channel, unlike the higher-quality S-Video and the even higher-quality component video. In all of these video formats, audio is carried on a separate connection.
An analogsynthesizer is a synthesizer that uses analog circuits and analog signals to generate sound electronically.
Modular synthesizers are synthesizers composed of separate modules for different functions. The modules can be connected together by the user to create a patch. The outputs from the modules may include audio signals, analog control voltages, or digital signals for logic or timing conditions. Typical modules are voltage-controlled oscillators, voltage-controlled filters, voltage-controlled amplifiers and envelope generators.
Component video is an analog video signal that has been split into two or more component channels. In popular use, it refers to a type of component analog video (CAV) information that is transmitted or stored as three separate signals. Component video can be contrasted with composite video in which all the video information is combined into a single signal that is used in analog television. Like composite, component cables do not carry audio and are often paired with audio cables.
CV/gate is an analog method of controlling synthesizers, drum machines, and similar equipment with external sequencers. The control voltage typically controls pitch and the gate signal controls note on-off.
Scanimate is an analog computer animation system developed from the late 1960s to the 1980s by Computer Image Corporation of Denver, Colorado.
A tuner is a subsystem that receives radio frequency (RF) transmissions, such as FM broadcasting, and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output. Broadcast FM/AM transmissions usually feed this intermediate frequency (IF) directly into a demodulator that converts the radio signal into audio-frequency signals that can be fed into an amplifier to drive a loudspeaker.
Moog Music Inc. is an American synthesizer company based in Asheville, North Carolina. It was founded in 1953 as R. A. Moog Co. by Robert Moog and his father and was renamed Moog Music in 1972. Its early instruments included the Moog synthesizer, followed by the Minimoog in 1970, two of the most influential electronic instruments of all time.
The Moog synthesizer is a modular synthesizer developed by the American engineer Robert Moog. Moog debuted it in 1964, and Moog's company R. A. Moog Co. produced numerous models from 1965 to 1981, and again from 2014. It was the first commercial synthesizer, and is credited with creating the analog synthesizer as it is known today.
A video synthesizer is a device that electronically creates a video signal. A video synthesizer is able to generate a variety of visual material without camera input through the use of internal video pattern generators. It can also accept and "clean up and enhance" or "distort" live television camera imagery. The synthesizer creates a wide range of imagery through purely electronic manipulations. This imagery is visible within the output video signal when this signal is displayed. The output video signal can be viewed on a wide range of conventional video equipment, such as TV monitors, theater video projectors, computer displays, etc.
PAiA Electronics, Inc. is an American synthesizer kit company that was started by John Simonton in 1967. It sells various musical electronics kits including analog synthesizers, theremins, mixers and various music production units designed by founder John Simonton, Craig Anderton, Marvin Jones, Steve Wood and others.
Polyphony is a property of musical instruments that means that they can play multiple independent melody lines simultaneously. Instruments featuring polyphony are said to be polyphonic. Instruments that are not capable of polyphony are monophonic or paraphonic.
VJing is a broad designation for realtime visual performance. Characteristics of VJing are the creation or manipulation of imagery in realtime through technological mediation and for an audience, in synchronization to music. VJing often takes place at events such as concerts, nightclubs, music festivals and sometimes in combination with other performative arts. This results in a live multimedia performance that can include music, actors and dancers. The term VJing became popular in its association with MTV's Video Jockey but its origins date back to the New York club scene of the 70s. In both situations VJing is the manipulation or selection of visuals, the same way DJing is a selection and manipulation of audio.
Daniel J. Sandin is an American video and computer graphics artist, designer and researcher. He is a Professor Emeritus of the School of Art & Design at University of Illinois at Chicago, and co-director of the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago. He is an internationally recognized pioneer in computer graphics, electronic art and visualization.
The Serge synthesizer is an analogue modular synthesizer system originally developed by Serge Tcherepnin, Rich Gold and Randy Cohen at CalArts in late 1972. The first 20 Serge systems were built in 1973 in Tcherepnin's home. Tcherepnin was a professor at CalArts at the time, and desired to create something like the exclusively expensive Buchla modular synthesizers "for the people that would be both inexpensive and powerful." After building prototypes, Tcherepnin went on to develop kits for students to affordably build their own modular synthesizer, production taking place unofficially on a second floor CalArts balcony. This led to Tcherepnin leaving CalArts in order to produce kits commercially, starting in 1974.
The Rutt/Etra Video Synthesizer is an analog raster manipulation device for image processing and real-time animation. The Rutt/Etra was co-invented by Steve Rutt and Bill Etra.
Synthesizers.com is an American company based in Tyler, Texas, founded by engineer Roger Arrick, which manufactures analog modular synthesizers for music and sound-effect creation.
Experimental Television Center is a 501(c)(3) nonprofit electronic and media art center.
The Video Noisefields (1974) by Steina and Woody Vasulka is an important example of early formal and technical experimentation with analog video. The video runs for twelve minutes and five seconds and materially visualizes the deflected energy of the electronic signal. The video switches between two sources throughout, which creates a flickering effect. The imagery is based on the deflection of electronic signals, and a colorizer is used to add color variation. In the video, a circular form materializes on the screen and presents a division between inner and outer. A pulsation between the two is sustained throughout.
