Roland TR-707
The Roland TR-707 Rhythm Composer is a drum machine released by the Roland Corporation in 1985. Features The TR-707 has fifteen digitally sampled sounds. The instrument is capable of 10-voice polyphony. The alternate bass drum, snare, and hi-hat sounds cannot be triggered simultaneously. The instruments are labeled as Bass Drum, Snare Drum, Low Tom, Mid Tom, Hi Tom, Rimshot, Cowbell, Hand Clap, Tambourine, Hi-Hat (Closed or Open), Cymbal (Crash or Ride), as well as an additional function labeled accent, which serves to rhythmically modify the volume of the other instruments. The instruments on the TR-707 are samples of recordings of actual acoustic instruments, and not synthesized individually like the instruments on the TR-808. The TR-707 provides four levels of shuffle that operate globally on the rhythm, as well as flam that can be applied to any step. The device offers 64 programmable patterns, which are editable via step-write or tap-write, that can be sequenced togeth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Audio Bit Depth
In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample. Examples of bit depth include Compact Disc Digital Audio, which uses 16 bits per sample, and DVD-Audio and Blu-ray Disc which can support up to 24 bits per sample. In basic implementations, variations in bit depth primarily affect the noise level from quantization error—thus the signal-to-noise ratio (SNR) and dynamic range. However, techniques such as dithering, noise shaping, and oversampling can mitigate these effects without changing the bit depth. Bit depth also affects bit rate and file size. Bit depth is only meaningful in reference to a PCM digital signal. Non-PCM formats, such as lossy compression formats, do not have associated bit depths. Binary representation A PCM signal is a sequence of digital audio samples containing the data providing the necessary information to reconstruc ...

Roland TR-909
The Roland TR-909 Rhythm Composer is a drum machine introduced by Roland Corporation in 1983, succeeding the TR-808. It was the first Roland drum machine to use samples for some sounds, and the first with MIDI functionality, allowing it to synchronize with other devices. Though it was a commercial failure, the 909 became influential in the development of electronic dance music genres such as techno, house and acid. Design The 909 was designed by Tadao Kikumoto, who also designed the Roland TB-303 synthesizer. Chief Roland engineer Makoto Muroi credited the design of the analog and pulse-code modulation voice circuits to "Mr Ou" and its software to "Mr Hoshiai". Whereas its predecessor, the TR-808, is known for its "boomy" bass, the 909 sounds aggressive and "punchy". It was the first Roland drum machine to use samples (prerecorded sounds), for its crash, ride and hi-hat sounds; other sounds are generated with analog synthesis. As the clap and snare are generated via ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roland TR-808
The Roland TR-808 Rhythm Composer, commonly known as the 808, is a drum machine manufactured by the Roland Corporation between 1980 and 1983. It was one of the first drum machines to allow users to program rhythms instead of using preset patterns. Unlike its nearest competitor at the time, the more expensive Linn LM-1, the 808 generates sounds using analog synthesis rather than by playing samples (prerecorded sounds). Launched when electronic music had yet to become mainstream, the 808 received mixed reviews for its unrealistic drum sounds and was a commercial failure. After building approximately 12,000 units, Roland discontinued the 808 after its semiconductors became impossible to restock. It was succeeded by the TR-909 in 1983. Over the course of the 1980s, the 808 attracted a cult following among underground musicians for its affordability on the used market, ease of use and idiosyncratic sounds, particularly its deep, booming bass drum. It became a cornerstone of the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Al Jeel
Al Jeel, also known as Jeel, Geel (Egyptian Arabic), is an Egyptian alternative to foreign popular forms of music that developed in the 1970s. Modeled after foreign rock and roll and pop music, Al Jeel became oriented around dance/pop, and had a background similar to reggae. Al Jeel also included many distinctively Egyptian characteristics, somewhat related to past Egyptian musical influences. One of the most famous Al Jeel performers is Hamid El Shaeri. Overview The style was called new wave by many, emphasizing the transition from the first form of Egyptian pop music to spring up in the 1960s, Sha'abi. Sha'abi had sprung up in the slums of Egypt as a type of ghetto music, but after a decade of popularity the educated youth of Egypt began to look for different styles of music. Internationally savvy, high-tech Al Jeel became the music of the educated, well-to-do youth. Sharing common roots with Algerian Raï and Pop-Raï, Al-Jeel incorporates Bedouin, Nubian, and Egyptian rhy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabic Pop Music
Arabic pop music or Arab pop music is a subgenre of pop music and Arabic music. Arabic pop is mainly produced and originated in Cairo, Egypt; as Egyptian music genre is by far the most widespread within the region. Also Beirut, Lebanon, and Gulf states come as secondary centers. It is an outgrowth of the Arabic film industry (mainly Egyptian movies), also predominantly located in Cairo. Since 2000, various locations in the Gulf countries have been producing Khaleeji pop music. The primary style is a genre that synthetically combines pop melodies with elements of different Arabic regional styles, called ''ughniyah'' ( ar, أغنية) or in English "song". It uses a wide variety of instruments, including electric guitars or electronic keyboards, as well as traditional Middle Eastern instruments like the oud, darbukka or qanun and many more. Another characteristic aspect of Arabic pop is the overall tone and mood of the songs. The majority of the songs are in a minor key, and t ...

Acid House
Acid house (also simply known as just "acid") is a subgenre of house music developed around the mid-1980s by DJs from Chicago. The style is defined primarily by the squelching sounds and basslines of the Roland TB-303 electronic bass synthesizer-sequencer, an innovation attributed to Chicago producers DJ Pierre of Phuture and Sleezy D. Acid house soon became popular in the United Kingdom and continental Europe, where it was played by DJs in the acid house and later rave scenes. By the late 1980s, acid house had moved into the British mainstream, where it had some influence on pop and dance styles. Acid house brought house music to a worldwide audience. The influence of acid house can be heard in later styles of dance music including trance, hardcore, jungle, big beat, techno and trip hop. Characteristics Acid house's minimalist sound combined house music's ubiquitous programmed four-on-the-floor 4/4 beat with the electronic squelch sound produced by the Roland TB-303 ele ...

House Music
House is a music genre characterized by a repetitive Four on the floor (music), four-on-the-floor beat and a typical tempo of 120 beats per minute. It was created by Disc jockey, DJs and music producers from Chicago metropolitan area, Chicago's underground Clubbing (subculture), club culture in the late 1970s, as DJs began altering disco songs to give them a more mechanical beat. House was pioneered by African Americans, African American DJs and producers in Chicago such as Frankie Knuckles, Ron Hardy, Jesse Saunders, Chip E., Steve "Silk" Hurley, Farley "Jackmaster" Funk, Marshall Jefferson, Phuture, and others. House music expanded to other American cities such as New York City and became a worldwide phenomenon. House has had a large effect on pop music, especially dance music. It was incorporated by major international pop artists including Whitney Houston, Janet Jackson ("Together Again (Janet Jackson song), Together Again"), Kylie Minogue, Pet Shop Boys and Madonna ("Vogu ...

EEPROM
EEPROM (also called E2PROM) stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed. EEPROMs are organized as arrays of floating-gate transistors. EEPROMs can be programmed and erased in-circuit, by applying special programming signals. Originally, EEPROMs were limited to single-byte operations, which made them slower, but modern EEPROMs allow multi-byte page operations. An EEPROM has a limited life for erasing and reprogramming, now reaching a million operations in modern EEPROMs. In an EEPROM that is frequently reprogrammed, the life of the EEPROM is an important design consideration. Flash memory is a type of EEPROM designed for high speed and high density, at the expense of large erase blocks (ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Read-only Memory
Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM cannot be electronically modified after the manufacture of the memory device. Read-only memory is useful for storing software that is rarely changed during the life of the system, also known as firmware. Software applications (like video games) for programmable devices can be distributed as plug-in cartridges containing ROM. Strictly speaking, ''read-only memory'' refers to memory that is hard-wired, such as diode matrix or a mask ROM integrated circuit (IC), which cannot be electronically changed after manufacture. Although discrete circuits can be altered in principle, through the addition of bodge wires and/or the removal or replacement of components, ICs cannot. Correction of errors, or updates to the software, require new devices to be manufactured and to replace the installed device. Floating-gate ROM semiconductor memory in the form of erasab ...
