Gulbransen
Gulbransen Company was a musical instrument manufacturer of player pianos and home organs in the United States. It also made reed organs. It was originally established in 1904 by Axel Gulbransen as Gulbransen Piano Company. In the history of musical instruments, Gulbransen is notable for several innovations. In its early years, Gulbransen made the first upright piano with a player piano mechanism in the same case. In the 1920s, thousands of player pianos were manufactured by the firm under the Gulbransen and Dickinson name. In the electronic organ era, Gulbransen pioneered several innovations in the production of home electronic organs that became industry standards: * Use of transistor circuitry * Built-in Leslie speaker system * Chime stop and Piano stop * '' Automatic rhythm'' (built-in drum machine) * ''Automatic walking bass'' (bass accompaniment) In 1957, Gulbransen released the first transistorized electric organ "Gulbransen ''Model B''" (Model 1100), Includes 195 ...

Seeburg Corporation
Seeburg was an American design and manufacturing company of automated musical equipment, such as orchestrions, jukeboxes, and vending equipment. Prior to manufacturing their signature jukebox suite of products, Seeburg was considered to be one of the "big four" of the top coin-operated phonograph companies alongside AMI, Wurlitzer, and Rock-Ola. At the height of jukebox popularity, Seeburg machines were synonymous with the technology and a major quotidian brand of American teenage life. The company went out of business after being sold to Stern Electronics in 1982. History Automated musical equipment, such as coin-operated phonographs and orchestrions, was manufactured under the J.P. Seeburg and Company name for most of its early years. Until 1956, the company was family-owned. The company was founded by Justus Percival Sjöberg from Gothenburg, Sweden. He moved to the United States after graduating from Chalmers University of Technology and used an Americanized spelling of h ...

Electronic Organ
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: * Hammond-style organs used in pop, rock and jazz; * digital church organs, which imitate pipe organs and are used primarily in churches; * other types including combo organs, home organs, and software organs. History Predecessors ;Harmonium The immediate predecessor of the electronic organ was the harmonium, or reed organ, an instrument that was common in homes and small churches in the late 19th and early 20th centuries. In a fashion not totally unlike that of pipe organs, reed organs generate sound by forcing air over a set of reeds by means of a bellows, usually operated by constantly pumping a set of pedals. While reed organs have limited tonal quality, they are small, inexpensive, self ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rodgers Instruments
Rodgers Instruments Corporation is an American manufacturer of classical and church organs. Rodgers was incorporated May 1, 1958 in Beaverton, Oregon by founders, Rodgers W. Jenkins and Fred Tinker, employees of Tektronix, Inc., of Portland, Oregon, and members of a Tektronix team developing transistor-based oscillator circuits. Rodgers was the second manufacturer of solid state oscillator-based organs, completing their first instrument in 1958 (the first was the Gulbransen "B" home organ, introduced in July 1957. Both the Rodgers and the Gulbransen had vacuum-tube amplifiers. In 1962, upon introducing solid-state amplifiers, Rodgers became the world's first all-transistor organ). Other Rodgers innovations in the electronic organ industry include solid-state organ amplifiers (1962), single-contact diode keying (1961), reed switch pedal keying for pedalboards (1961), programmable computer memory pistons (1966), and the first MIDI-supported church organs (1986).

Reed Organ
The pump organ is a type of free-reed organ that generates sound as air flows past a vibrating piece of thin metal in a frame. The piece of metal is called a reed. Specific types of pump organ include the reed organ, harmonium, and melodeon. The idea for the free reed was imported from China through Russia after 1750, and the first Western free-reed instrument was made in 1780 in Denmark. More portable than pipe organs, free-reed organs were widely used in smaller churches and in private homes in the 19th century, but their volume and tonal range were limited. They generally had one or sometimes two manuals, with pedal-boards being rare. The finer pump organs had a wider range of tones, and the cabinets of those intended for churches and affluent homes were often excellent pieces of furniture. Several million free-reed organs and melodeons were made in the US and Canada between the 1850s and the 1920s, some of which were exported. The Cable Company, Estey Organ, and Mason & ...

Piano Manufacturing Companies Of The United States
The piano is a stringed keyboard instrument in which the strings are struck by wooden hammers that are coated with a softer material (modern hammers are covered with dense wool felt; some early pianos used leather). It is played using a keyboard, which is a row of keys (small levers) that the performer presses down or strikes with the fingers and thumbs of both hands to cause the hammers to strike the strings. It was invented in Italy by Bartolomeo Cristofori around the year 1700. Description The word "piano" is a shortened form of ''pianoforte'', the Italian term for the early 1700s versions of the instrument, which in turn derives from ''clavicembalo col piano e forte'' (key cimbalom with quiet and loud)Pollens (1995, 238) and ''fortepiano''. The Italian musical terms ''piano'' and ''forte'' indicate "soft" and "loud" respectively, in this context referring to the variations in volume (i.e., loudness) produced in response to a pianist's touch or pressure on the keys: the grea ...

Generalmusic
Generalmusic was an Italian musical instrument manufacturing company focusing on digital and acoustic pianos, synthesizers and music workstations. The company produced three lines: a musical instrument series called GEM, a various studio equipment series called LEM and electric organs/synthesizers called ELKA. It was founded in 1987 and ceased business in 2009 before becoming bankrupt in 2011. History Early Years Generalmusic's first arranger workstation models were their WS series, released in 1990. Featuring a 5-track sequencer, 32 built-in arranger styles, and 32 user-programmable styles, they predated the General MIDI standard. This limited easy interoperability with other devices. The WX series (released in 1993) did implement General MIDI, offered a large blue LCD display, a user-friendly interface and some vintage synth sound presets like Oberheim, ARP 2600, Prophet or Elka Synthex. Although designed as arranger workstations, WX series had some professional synthesizer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flip-flop (electronics)
In electronics, a flip-flop or latch is a circuit that has two stable states and can be used to store state information – a bistable multivibrator. The circuit can be made to change state by signals applied to one or more control inputs and will have one or two outputs. It is the basic storage element in sequential logic. Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems. Flip-flops and latches are used as data storage elements. A flip-flop is a device which stores a single ''bit'' (binary digit) of data; one of its two states represents a "one" and the other represents a "zero". Such data storage can be used for storage of ''state'', and such a circuit is described as sequential logic in electronics. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current state (and hence, previous inputs). It can also b ...

Electronics
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small ...

Drum Sequencer (controller)
A cam timer or drum sequencer is an electromechanical system for controlling a sequence of events automatically. It resembles a music box with movable pins, controlling electrical switches instead of musical notes. Description An electric motor drives a shaft on which is arranged a series of cams or a drum studded with pegs along its surface. Associated with each cam is one or more switches. The motor rotates at a fixed speed, and the camshaft is driven through a speed reducing gearbox at a convenient slow speed. Indentations or protrusions on the cams operate the switches at different times. By arrangement of the cams and switches, complex sequences of opening and closing switches can be made. The switches then operate different elements of the controlled system - for example motors, valves, etc. A programmer may change or rearrange (reprogram) peg or cam positions. Much like the pegs in a music box cylinder activate the notes, in a drum sequencer, as the drum of the sequence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechatronics
Mechatronics engineering also called mechatronics, is an interdisciplinary branch of engineering that focuses on the integration of mechanical, electrical and electronic engineering systems, and also includes a combination of robotics, electronics, computer science, telecommunications, systems, control, and product engineering. As technology advances over time, various subfields of engineering have succeeded in both adapting and multiplying. The intention of mechatronics is to produce a design solution that unifies each of these various subfields. Originally, the field of mechatronics was intended to be nothing more than a combination of mechanics, electrical and electronics, hence the name being a portmanteau of the words "mechanics" and "electronics"; however, as the complexity of technical systems continued to evolve, the definition had been broadened to include more technical areas. The word ''mechatronics'' originated in Japanese-English and was created by Tetsuro Mori, an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
