A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds. This in contrast to older analog synthesizers, which produce music using analog electronics, and samplers, which play back digital recordings of acoustic, electric, or electronic instruments. Some digital synthesizers emulate analog synthesizers; others include sampling capability in addition to digital synthesis.
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.
An electronic keyboard, portable keyboard, or digital keyboard is an electronic musical instrument based on keyboard instruments. Electronic keyboards include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. In technical terms, an electronic keyboard is a rompler-based synthesizer with a low-wattage power amplifier and small loudspeakers.
ARP Instruments, Inc. was a Lexington, Massachusetts manufacturer of electronic musical instruments, founded by Alan Robert Pearlman in 1969. It created a popular and commercially successful range of synthesizers throughout the 1970s before declaring bankruptcy in 1981. The company earned a reputation for producing excellent sounding, innovative instruments and was granted several patents for the technology it developed.
Farfisa is a manufacturer of electronics based in Osimo, Italy, founded in 1946. The company manufactured a series of compact electronic organs in the 1960s and 1970s, including the Compact, FAST, Professional and VIP ranges, and later, a series of other keyboard instruments. They were used by a number of popular musicians including Sam the Sham, Country Joe and the Fish, Pink Floyd, Sly Stone, Blondie, and the B-52s.
Behringer is an audio equipment company founded by the Swiss engineer Uli Behringer on 25 January 1989 in Willich, Germany. Behringer produces equipment including synthesizers, mixers, audio interfaces and amplifiers. Behringer is owned by Music Tribe, a holding company chaired by Uli Behringer.
An electric organ, also known as electronic organ, is an electronic keyboard instrument which was derived from the harmonium, pipe organ and theatre organ. Originally designed to imitate their sound, or orchestral sounds, it has since developed into several types of instruments:
Guitar Organ or GuitOrgan is a type of electric guitar with electronic organ components added, developed by Jennings Musical Industry as Vox Guitar Organ at latest in 1965. Similar instrument, GuitOrgan was developed by Murrell Electronics, circa 1967. On this type of instruments, each guitar fret is separated into six segments, creating independent contact switches for each string. The organ notes are keyed when a string touches a specific segment. An expression pedal is used to fade the organ sound in and out, while the guitar can be played at the same time.
Electone is the trademark used for electronic organs produced by Yamaha. With the exception of the top end performance models, most Electones are based on the design of the spinet electronic organ. Current models are completely digital and contain a variety of sounds, effects, and accompaniments, on top of the ability to store programming data onto memory devices.
Crumar is an Italian manufacturer of electronic musical instruments. It was established by Mario Crucianelli in the late 1960s, and manufactured synthesizers and keyboards during the '70s and '80s. Its name is a portmanteau of "Crucianelli" and the name of his business partner, Marchetti. The company appears to have grown out of the Crucianelli accordion company and also continued to manufacture accordions under both names.
Chorus is an audio effect that occurs when individual sounds with approximately the same time, and very similar pitches, converge. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device.
Allen Organ Company LLC builds church organs, home organs, and theatre organs. Its factory is located in Macungie, Pennsylvania. The Allen International Sales Headquarters also includes the Jerome Markowitz Memorial Center, a museum. It displays many instruments that represent technological milestones in the development of the pipeless, electronic organ.
Rocky Mount Instruments (RMI) was a subsidiary of the Allen Organ Company, based in Rocky Mount, North Carolina, active from 1966 to 1982. The company was formed to produce portable musical instruments, and manufactured several electronic pianos, harpsichords, and organs that used oscillators to create sound, instead of mechanical components like an electric piano.
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.
The Solina String Synthesizer, also erroneously known as the ARP Solina String Synthesizer or sometimes the ARP String Synthesizer, is a combination of a string synthesizer and synthesizer. It is a hybrid model which combined both the Solina String Ensemble string synthesizer and the ARP Explorer monophonic synthesizer. It was built in Bodegraven, Netherlands by Eminent B.V. Supposedly only about 100 were ever produced. The addition of the ARP Explorer to the Solina string sounds made for a very powerful combination.
The Solina String Ensemble, also marketed as the ARP String Ensemble, is a fully polyphonic multi-orchestral synthesizer with a 49-key keyboard, produced by Eminent BV. It was distributed in the United States by ARP Instruments from 1974 to 1981. The sounds it incorporates are violin, viola, trumpet, horn, cello, and contrabass. The keyboard uses 'organ style' divide-down technology to make it polyphonic. The built-in chorus effect gives the instrument its distinctive sound.
Viscount International SpA (Viscount) is a musical instrument manufacturer based in Mondaino, Italy. The brand Viscount was registered in 1969 by Marcello Galanti, but the company was established in the late 19th century by his forefather Antonio Galanti. After 1969 Viscount's primary focus has been on classic organs and digital pianos. Several alternative brands were formed in the 2000s to aim at expanding into other markets: VERSE and Voice Systems, respectively, for the high and low-end Pro-Audio markets and Physis for digital organs using Viscount's physical modeling technology. The company also used the Oberheim brand for several years, to market vintage organs, synthesizers and guitar effects. Currently, Viscount's manufacturing and R&D activity is based in Italy. The company has been continuously owned by the Galanti family since its inception.
The Eminent 310 Unique is a home electronic organ that was built and introduced in 1972 by the Dutch organ manufacturer Eminent, at the time based in Bodegraven, the Netherlands. It was the first organ to include a string section, making it the first commercial polyphonic string synthesizer on the market. It is prominently featured on Jean Michel Jarre's albums Oxygène (1977) and Équinoxe (1978).
A string synthesizer or string machine is a specialized synthesizer designed specifically to make sounds similar to that of a string orchestra. Dedicated string synthesizers occupied a specific musical instrument niche between electronic organs and general-purpose synthesizers in the 1970s and early 1980s, until advances in digital signal processing technology allowed the production of inexpensive general-purpose polyphonic synthesizers and samplers, which made the existence of a separate type of instrument unnecessary.
The history of home keyboards lies in mechanical musical instrument keyboards, electrified keyboards and 1960s and 1970s synthesizer technologies.
