Aftertouch
Keyboard expression is the ability of a keyboard musical instrument to change tone or other qualities of the sound in response to velocity, pressure or other variations in how the performer depresses the keys of the musical keyboard. Expression types include: * ''Velocity sensitivity''—how fast the key is pressed * ''Aftertouch'', or ''pressure sensitivity'' — the amount of pressure on a key, once already held down * ''Displacement sensitivity''—distance that a key is pressed down Keyboard instruments offer a range of expression types. Acoustic pianos, such as upright and grand pianos, are velocity-sensitive—the faster the key strike, the harder the hammer hits the strings. Baroque-style clavichords and professional synthesizers are aftertouch-sensitive—applied force on the key after the initial strike produces effects such as vibrato or swells in volume. Tracker pipe organs and some electronic organs are displacement-sensitive—partly depressing a key produces a quie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musical Keyboard
A musical keyboard is the set of adjacent depressible levers or keys on a musical instrument. Keyboards typically contain keys for playing the twelve notes of the Western musical scale, with a combination of larger, longer keys and smaller, shorter keys that repeats at the interval of an octave. Pressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine ( acoustic and electric piano, clavichord), plucking a string (harpsichord), causing air to flow through a pipe organ, striking a bell (carillon), or activating an electronic circuit (synthesizer, digital piano, electronic keyboard). Since the most commonly encountered keyboard instrument is the piano, the keyboard layout is often referred to as the piano keyboard or simply piano keys. Description The twelve notes of the Western musical scale are laid out with the lowest note on the left. The longer keys (for the seven "natural" notes of the C major scale: C, D, E, F ...

Continuum (instrument)
The Continuum Fingerboard or Haken Continuum is a music performance controller and synthesizer developed by Lippold Haken, a professor of Electrical and Computer Engineering at the University of Illinois, and sold by Haken Audio, located in Champaign, Illinois. The Continuum Fingerboard was initially developed from 1983 to 1998 at the CERL Sound Group at the University of Illinois, to control sound-producing algorithms on the Platypus audio signal processor and the Kyma/Capybara workstation. In 1999, the first Continuum Fingerboard was commercially sold. Until 2008, the Continuum Fingerboard provided IEEE-1394 (FireWire) connections to control a Kyma sound design workstation, as well as MIDI connections to control a MIDI synthesizer module. More recently, the Continuum Fingerboard generates audio directly in addition to providing MIDI connections for MIDI modules, software synthesizers, and Kyma (the IEEE-1394 connection that was present on earlier models has been removed). ...

Synthesizer
A synthesizer (also synthesiser or synth) is an electronic musical instrument that generates audio signals. Synthesizers typically create sounds by generating waveforms through methods including subtractive synthesis, additive synthesis and frequency modulation synthesis. These sounds may be altered by components such as filters, which cut or boost frequencies; envelopes, which control articulation, or how notes begin and end; and low-frequency oscillators, which modulate parameters such as pitch, volume, or filter characteristics affecting timbre. Synthesizers are typically played with keyboards or controlled by sequencers, software or other instruments, and may be synchronized to other equipment via MIDI. Synthesizer-like instruments emerged in the United States in the mid-20th century with instruments such as the RCA Mark II, which was controlled with punch cards and used hundreds of vacuum tubes. The Moog synthesizer, developed by Robert Moog and first so ... [...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. ...

Yamaha EX5
The Yamaha EX5 is a synthesizer/workstation produced by Yamaha from 1998 to 2000. The EX5 combines several methods of sound generation (see below). The later released EX7 was a cheaper version of the EX5 with fewer keys, polyphony, sounds and functions. The Yamaha EX music synthesizers, along with the early Yamaha S series, were the predecessors of the Motif workstation series. Features The Yamaha EX5 (EX stands for Extended Synthesis) uses four different tone generators for generating sounds. These are AWM2 ("Advanced Wave Memory, 2nd Generation" PCM-subtractive), AN (Analog Physical Modeling), FDSP (Formulated Digital Sound Processing) and VL (Virtual Acoustic) synthesis. The fifth sound source is ser-RAM/flashROM [Sample-based synthesis. Sound patches ("Voices") can be assembled from either a maximum of four AWM2 oscillators ("Elements"), or a combination variously fewer AWM2 Elements with two AN Elements (either layered or duophonically), or one monophonic VL Element, or ...

Digital Piano
A digital piano is a type of electronic keyboard instrument designed to serve primarily as an alternative to the traditional acoustic piano, both in how it feels to play and in the sound it produces. Digital pianos use either synthesized emulation or recorded samples of an acoustic piano, which are played through one or more internal loudspeakers. They also incorporate weighted keys, which recreate the feel of an acoustic piano. Some digital pianos are designed to also look like an upright or grand piano. Others may be very simple, without a stand. While digital pianos may sometimes fall short of acoustic ones in feel and sound, their advantages include being smaller, weighing much less, and costing less than an acoustic piano. In addition, they do not need to be tuned, and their tuning can be modified to match the tuning of another instrument (e.g. a pipe organ). Like other electronic musical instruments, they can be connected to an amplifier or a PA system to produce a sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organ (music)
Carol Williams performing at the West_Point_Cadet_Chapel.html" ;"title="United States Military Academy West Point Cadet Chapel">United States Military Academy West Point Cadet Chapel. In music, the organ is a keyboard instrument of one or more Pipe organ, pipe divisions or other means (generally woodwind or electronic musical instrument, electric) for producing tones. The organs have usually two or three, sometimes up to five or more, manuals for playing with the hands and a pedalboard for playing with the feet. With the use of registers, several groups of pipes can be connected to one manual. The organ has been used in various musical settings, particularly in classical music. Music written specifically for the organ is common from the Renaissance to the present day. Pipe organs, the most traditional type, operate by forcing air through pipes of varying sizes and materials, each producing a different pitch and tone. These instruments are commonly found in churches and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIDI Controller
A MIDI controller is any hardware or software that generates and transmits Musical Instrument Digital Interface (MIDI) data to MIDI-enabled devices, typically to trigger sounds and control parameters of an electronic music performance. They most often use a musical keyboard to send data about the pitch of notes to play, although a MIDI controller may trigger lighting and other effects. A wind controller has a sensor that converts breath pressure to volume information and lip pressure to control pitch. Controllers for percussion and stringed instruments exist, as well as specialized and experimental devices. Some MIDI controllers are used in association with specific digital audio workstation software. The original MIDI specification has been extended to include a greater range of control features. Features MIDI controllers usually do not create or produce musical sounds by themselves. MIDI controllers typically have some type of interface that the performer presses, strikes ...

Keyboard Instrument
A keyboard instrument is a musical instrument played using a keyboard, a row of levers that are pressed by the fingers. The most common of these are the piano, organ, and various electronic keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas, which are struck idiophones operated by a keyboard, and carillons, which are usually housed in bell towers or belfries of churches or municipal buildings. Today, the term ''keyboard'' often refers to keyboard-style synthesizers and arrangers as well as work-stations. These keyboards typically work by translating the physical act of pressing keys into electrical signals that produce sound. Under the fingers of a sensitive performer, the keyboard may also be used to control dynamics, phrasing, shading, articulation, and other elements of expression—depending on the design and inherent capabilities of the instrument. Modern keyboards, especially digital ones, can simulate a wide range of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soft Pedal
The soft pedal or , is one pedal on a piano, generally placed leftmost among the pedals. On a grand piano this pedal shifts the whole action (including the keyboard) slightly to the right, so that the hammers, which normally strike all three of the strings for a note, strike only two of them. This softens the note and also modifies its tone quality. Tone quality is also affected by forcing the remaining two strings being struck to make contact with a part of the hammer felt which is not often hit (due to the whole action being shifted); this results in a duller sound, as opposed to the bright sound which is usually produced (due to the felt being hardened from regular use). History The essential function of the soft pedal was invented by Bartolomeo Cristofori, the inventor of the piano. On some of his pianos, it was possible to move the hammer mechanism so that the hammers struck just one of the two strings per note. Cristofori's mechanism was a hand stop, necessitating a ...

Sympathetic Resonance
Sympathetic resonance or sympathetic vibration is a harmonic phenomenon wherein a passive string or vibratory body responds to external vibrations to which it has a harmonic likeness. The classic example is demonstrated with two similarly-tuned tuning forks. When one fork is struck and held near the other, vibrations are induced in the unstruck fork, even though there is no physical contact between them. In similar fashion, strings will respond to the vibrations of a tuning fork when sufficient harmonic relations exist between them. The effect is most noticeable when the two bodies are tuned in unison or an octave apart (corresponding to the first and second harmonics, integer multiples of the inducing frequency), as there is the greatest similarity in vibrational frequency. Sympathetic resonance is an example of injection locking occurring between coupled oscillators, in this case coupled through vibrating air. In musical instruments, sympathetic resonance can produce both de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
