Seiko DS-250
The DS-250 was an electronic keyboard manufactured in 1985 by Seiko and was considered a commercial failure. It was capable of generating both digital and additive sounds. It is expandable with two expander units DS-310 and DS-320. Features The unit used additive synthesis for sound generation, chorus and ports included MIDI In, Out and Through, RCA outputs (stereo), Headphones and level controls for both channels. It also has on board speakers. It is capable of running either a single sound or two sounds at once, either layered or split, and each of these can be used on its own MIDI channel (there are small dials on the end of the keyboard to set each channel). There are 16 preset sounds and these are all editable within a very limited context of volume, sustain (3 levels) and a variable vibrato (with vibrato delay switch). You can change the detune and pitch intervals between the two layered sounds. DS1000 sequencer A MIDI 1000 note sequencer called the DS1000 was also produce ...

Seiko
, commonly known as Seiko ( , ), is a Japanese maker of watches, clocks, electronic devices, and semiconductors. Founded in 1881 by Kintarō Hattori in Tokyo, Seiko introduced the world's first commercial quartz wristwatch in 1969. Seiko is widely known for its wristwatches. Seiko and Rolex are the only two watch companies considered to be vertically integrated. Seiko is able to design and develop all the components of a watch, as well as assemble, adjust, inspect and ship them in-house. Seiko's mechanical watches consist of approximately 200 parts, and the company has the technology and production facilities to design and manufacture all of these parts in-house. The company was incorporated (K. Hattori & Co., Ltd.) in 1917 and renamed Hattori Seiko Co., Ltd. in 1983 and Seiko Corporation in 1990. After reconstructing and creating its operating subsidiaries (such as Seiko Watch Corporation and Seiko Clock Inc.), it became a holding company in 2001 and was renamed Seiko Hol ...

Digital Synthesizer
A digital synthesizer is a synthesizer that uses digital signal processing (DSP) techniques to make musical sounds, 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, while others include sampling capability in addition to digital synthesis. History The very earliest digital synthesis experiments were made with computers, as part of academic research into sound generation. In 1957, the first programming language for computer music, MUSIC, was developed by Max Mathews on an IBM 704 at Bell Labs in 1957. It generates digital audio waveforms through direct synthesis. , EMS MUSYS 3 system was developed by Peter Grogono (software), David Cockerell (hardware and interfacing) and Peter Zinovieff (system design and operation) at their London (Putney) Studio. The system ran on two mini-co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Additive Synthesis
Additive synthesis is a sound synthesis technique that creates timbre by adding sine waves together. The timbre of musical instruments can be considered in the light of Fourier series, Fourier theory to consist of multiple harmonic or inharmonic ''Harmonic series (music)#Partial, partials'' or overtones. Each partial is a sine wave of different frequency and amplitude that swells and decays over time due to modulation from an ADSR envelope or low frequency oscillator. Additive synthesis most directly generates sound by adding the output of multiple sine wave generators. Alternative implementations may use pre-computed Wavetable synthesis, wavetables or the inverse fast Fourier transform. Explanation The sounds that are heard in everyday life are not characterized by a single frequency. Instead, they consist of a sum of pure sine frequencies, each one at a different amplitude. When humans hear these frequencies simultaneously, we can recognize the sound. This is true for both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIDI
Musical Instrument Digital Interface (; MIDI) is an American-Japanese technical standard that describes a communication 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. A single MIDI cable can carry up to sixteen channels of MIDI data, each of which can be routed to a separate device. Each interaction with a key, button, knob or slider is converted into a MIDI event, which specifies musical instructions, such as a note's pitch, timing and velocity. One common MIDI application is to play a MIDI keyboard or other controller and use it to trigger a digital sound module (which contains synthesized musical sounds) to generate sounds, which the audience hears produced by a keyboard amplifier. MIDI data can be transferred via MIDI or USB cable, or recorded to a sequencer or digital audio workstation to be edited or played back. ...

Electronic Keyboard
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. Electronic keyboards offer a diverse selection of instrument sounds (piano, organ, violin, etc.) along with synthesizer tones. Designed primarily for beginners and home users, they generally feature unweighted keys. While budget models lack velocity sensitivity, mid-range options and above often include it. These keyboards have limited sound editing options, focusing on preset sounds. Casio and Yamaha Corporation, Yamaha are major manufacturers in this market, known for popularizing the concept since the 1980s.

Jean-Michel Jarre
Jean-Michel André Jarre (; born 24 August 1948) is a French composer, performer and record producer. He is a pioneer in the Electronic music, electronic, Ambient music, ambient and New-age music, new-age genres, and is known for organising outdoor spectacles featuring his music, accompanied by vast Laser lighting display, laser displays, large Projector, projections and fireworks. Jarre was raised in Lyon by his mother and grandparents and trained on the piano. From an early age, he was introduced to a variety of art forms, including street performers, jazz musicians and the artist Pierre Soulages. His musical style was perhaps most heavily influenced by Pierre Schaeffer, a pioneer of musique concrète at the Groupe de Recherches Musicales. His first mainstream success was the 1976 album ''Oxygène''. Recorded in a makeshift studio at his home, the album sold an estimated 18 million copies. ''Oxygène'' was followed in 1978 by ''Equinoxe, Équinoxe'', and in 1979, Jarre p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rendez-Vous (Jean-Michel Jarre Album)
''Rendez-Vous'' is the eighth studio album by electronic musician and composer Jean-Michel Jarre released on Disques Dreyfus, licensed to Polydor, in 1986. The album art was created by long-time collaborator Michel Granger. Composition and recording ''Rendez-Vous'' was created over a period of about two months. It features heavy use of the Elka Synthex, notably so on "Second Rendez-Vous", a track Jarre often performs using a laser harp. As with '' Zoolook'', it contains elements from the album '' Musique pour Supermarché'', in this case it is in "Fifth Rendez-Vous". Some of the other musical themes on ''Rendez-Vous'' were recycled from various singles Jarre wrote and produced for Gérard Lenorman in the 1970s. Jarre also developed "Fourth Rendez-Vous" from a discarded demo at collaborator Michel Geiss urging, noting that its success as both a single and live staple did little to dissuade his contempt for the song. "Second Rendez-Vous" was inspired by American musician Wendy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric And Electronic Keyboard Instruments
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...
