Roland V-Drums
V-Drums (Virtual Drums) are a line of electronic drums by Roland Corporation Introduced originally in 1997. Trigger types V-Drums trigger devices are of four major types: mesh-head drum pads, rubber pads, cymbal pads and acoustic drum triggers. Mesh-head pads look very similar to acoustic drums, and attempt to emulate their feel. The simpler, more generic type is a rubber pad, which is less expensive, but also looks and feels less like an acoustic drum. There are several models of cymbal pads (also called V-Cymbals). The more expensive ones attempt to emulate the physical properties of acoustic cymbals of various types (e.g.: hi-hat, crash, ride), while the simpler, less expensive cymbal pads are less realistic. Acoustic drum triggers can be used to provide trigger signals from standard acoustic drums. From an electrical point of view, trigger pads can be of the following types: * ''Mono Pads'', using ''one'' Piezoelectric sensor for the head. Usually kick-drum pads or ...

Roland Drums 2020 By Glenn Francis
Roland (; frk, *Hrōþiland; lat-med, Hruodlandus or ''Rotholandus''; it, Orlando or ''Rolando''; died 15 August 778) was a Frankish military leader under Charlemagne who became one of the principal figures in the literary cycle known as the Matter of France. The historical Roland was military governor of the Breton March, responsible for defending Francia's frontier against the Bretons. His only historical attestation is in Einhard's ''Vita Karoli Magni'', which notes he was part of the Frankish rearguard killed in retribution by the Basques in Iberia at the Battle of Roncevaux Pass. The story of Roland's death at Roncevaux Pass was embellished in later medieval and Renaissance literature. The first and most famous of these epic treatments was the Old French ''Chanson de Roland'' of the 11th century. Two masterpieces of Italian Renaissance poetry, the ''Orlando Innamorato'' and '' Orlando Furioso'' (by Matteo Maria Boiardo and Ludovico Ariosto respectively), are even f ...

Ambient Noise Level
In atmospheric sounding and noise pollution, ambient noise level (sometimes called background noise level, reference sound level, or room noise level) is the background sound pressure level at a given location, normally specified as a reference level to study a new intrusive sound source. Ambient sound levels are often measured in order to map sound conditions over a spatial regime to understand their variation with locale. In this case the product of the investigation is a sound level contour map. Alternatively ambient noise levels may be measured to provide a reference point for analyzing an intrusive sound to a given environment. For example, sometimes aircraft noise is studied by measuring ambient sound without presence of any overflights, and then studying the noise addition by measurement or computer simulation of overflight events. Or roadway noise is measured as ambient sound, prior to introducing a hypothetical noise barrier intended to reduce that ambient noise lev ...

CompactFlash
CompactFlash (CF) is a flash memory mass storage device used mainly in portable electronic devices. The format was specified and the devices were first manufactured by SanDisk in 1994. CompactFlash became one of the most successful of the early memory card formats, surpassing Miniature Card and SmartMedia. Subsequent formats, such as MMC/ SD, various Memory Stick formats, and xD-Picture Card offered stiff competition. Most of these cards are smaller than CompactFlash while offering comparable capacity and speed. Proprietary memory card formats for use in professional audio and video, such as P2 and SxS, are faster, but physically larger and more costly. CompactFlash's popularity is declining as CFexpress is taking over. As of 2022, both Canon and Nikon newest high end cameras, e.g. the Canon EOS R5, Canon EOS R3, and Nikon Z 9 use CFexpress cards for the higher performance required to record 8K video. Traditional CompactFlash cards use the Parallel ATA interface, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bluetooth
Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to . It employs UHF radio waves in the ISM bands, from 2.402GHz to 2.48GHz. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices and connect cell phones and music players with wireless headphones. Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The IEEE standardized Bluetooth as IEEE 802.15.1, but no longer maintains the standard. The Bluetooth SIG oversees development of the specification, manages the qualification program, and protects the trademarks. A manufacturer must meet ...

Secure Digital
Secure Digital, officially abbreviated as SD, is a proprietary non-volatile flash memory card format developed by the SD Association (SDA) for use in portable devices. The standard was introduced in August 1999 by joint efforts between SanDisk, Panasonic (Matsushita) and Toshiba as an improvement over MultiMediaCards (MMCs), and has become the industry standard. The three companies formed SD-3C, LLC, a company that licenses and enforces intellectual property rights associated with SD memory cards and SD host and ancillary products. The companies also formed the SD Association (SDA), a non-profit organization, in January 2000 to promote and create SD Card standards. SDA today has about 1,000 member companies. The SDA uses several trademarked logos owned and licensed by SD-3C to enforce compliance with its specifications and assure users of compatibility. History 1999–2003: Creation In 1999, SanDisk, Panasonic (Matsushita), and Toshiba agreed to develop and market the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Variable Resistor
A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load. Nomenclature There are a number of terms in the electronics industry used to describe certain types of potentiometers: * slide pot or slider pot: a potentiome ...

Remo
Remo Inc. is an American musical instruments manufacturing company based in Valencia, California, and founded by Remo Belli in 1957. Products manufactured include drum kits, drumhead A drumhead or drum skin is a membrane stretched over one or both of the open ends of a drum. The drumhead is struck with sticks, mallets, or hands, so that it vibrates and the sound resonates through the drum. Additionally outside of percu ...s, drums, and drum hardware, hardware. History Drummer and founder Remo D. Belli experimented with PET film (biaxially oriented), PET film as a possible material for the production of drumheads after World War II due to its consistency in tonal qualities and resistance to weather changes. Throughout the 1960s, it was a fight to gain market acceptance, as purist jazzmen preferred the sound of natural calfskin. However, these calfskin drumheads had to be frequently tuned with weather fluctuations. Remo Belli created convenience for professional dr ...

Trampoline
A trampoline is a device consisting of a piece of taut, strong fabric stretched between a steel frame using many coiled springs. Not all trampolines have springs, as the Springfree Trampoline uses glass-reinforced plastic rods. People bounce on trampolines for recreational and competitive purposes. The fabric that users bounce on (commonly known as the "bounce mat" or "trampoline bed") is not elastic itself; the elasticity is provided by the springs that connect it to the frame, which store potential energy. History Early trampoline-like devices A game similar to trampolining was developed by the Inuit, who would toss blanket dancers into the air on a walrus skin one at a time (see Nalukataq) during a spring celebration of whale harvest. There is also some evidence of people in Europe having been tossed into the air by a number of people holding a blanket.

Tom-tom Drum
A tom drum is a cylindrical drum with no snares, named from the Anglo-Indian and Sinhala language. It was added to the drum kit in the early part of the 20th century. Most toms range in size between in diameter, though floor toms can go as large as . It is not to be confused with a tam-tam, a gong. Design history The drum called "Thammattama", played by the Sinhala people of Sri Lanka, is used in a number of Buddhist rituals in that country. It is commonly heard in Buddhist temples paired along with the reed instrument called horanava. This may be etymologically derived from the Tamil term "Thappattam" or "Thappu", a frame drum associated with South Indian Tamil culture. However, the tom-tom drums on the Western drum set clearly resemble the Sri Lankan version more than the frame drum. The British colonists complained loudly about the noise generated by the "tom-toms" of the natives throughout South Asia. It is likely that the term tom-toms thus comes from their experie ...

Piezoelectric Sensor
A piezoelectric sensor is a device that uses the piezoelectric effect to measure changes in pressure, acceleration, temperature, strain, or force by converting them to an electrical charge. The prefix ''piezo-'' is Greek for 'press' or 'squeeze'. Applications Piezoelectric sensors are versatile tools for the measurement of various processes. They are used for quality assurance, process control, and for research and development in many industries. Pierre Curie discovered the piezoelectric effect in 1880, but only in the 1950s did manufacturers begin to use the piezoelectric effect in industrial sensing applications. Since then, this measuring principle has been increasingly used, and has become a mature technology with excellent inherent reliability. They have been successfully used in various applications, such as in medical, aerospace, nuclear instrumentation, and as a tilt sensor in consumer electronics or a pressure sensor in the touch pads of mobile phones.

Ride Cymbal
The ride cymbal is a standard cymbal in most drum kits. Its function in the kit is to maintain a beat,Schroedl, Scott (2001). ''Play Drums Today!'', p.7. Hal Leonard. . "It's called the ride cymbal because you 'ride' on it--that is, you maintain a steady pattern." sometimes called a ride pattern, rather than the accent of a crash. It is normally placed on the extreme right (or dominant hand) of a drum set, above the floor tom.Peckman, Jonathan (2007). ''Picture Yourself Drumming'', p.195. . The ride can fulfill any function or rhythm the hi-hat does, with the exception of an open and closed sound. The ride is played with a drumstick. Terminology The term ''ride'' means ''to ride with the music'', describing the cymbal's sustain after it is struck. The term may depict either the function or characteristic of the instrument. Most cymbal makers manufacture specific cymbals for the purpose. Some drummers use a china cymbal, a sizzle cymbal or a specialized tone such as a s ...
