Roland MKS-20
The Roland MKS-20 is a digital piano–type sound module released by Roland Corporation in 1986, simultaneously with the Roland RD-1000 digital stage piano. The MKS-20 and RD-1000 share the same "Structured/Adaptive Synthesis" sound engine; the RD-1000 integrates that engine into a musical keyboard-type MIDI controller with size, weight, and features similar to the Roland MKB-1000. Both the RD-1000 and MKS-20 feature eight keyboard sounds, including grand piano, electric piano, harpsichord, vibraphone, and clavinet. Both have three effects units built in: stereo chorus, stereo tremolo, and a three-band equalizer with a sweepable mid-range. Features Structured / adaptive synthesis Roland's structured/adaptive synthesis (SAS) has been described as a "sophisticated re-synthesis technique which involves a highly accurate computer analysis of 'real' sounds, from which a near replica can be synthesised." Roland engineers created samples of each of the 88 keys of various grand pianos, pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Chorus Effect
Chorus is an audio effect that occurs when individual sounds with approximately the same time, and very similar pitches, converge. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device. When the effect is produced successfully, none of the constituent sounds are perceived as being out of tune. It is characteristic of sounds with a rich, shimmering quality that would be absent if the sound came from a single source. The shimmer occurs because of beating. The effect is more apparent when listening to sounds that sustain for longer periods of time. The chorus effect is especially easy to hear when listening to a choir or string ensemble. A choir has multiple people singing each part (alto, tenor, etc.). A string ensemble has multiple violinists and possibly multiples of other stringed instruments. Acoustically created Although ...

Phaser (effect)
A phaser is an electronic sound processor used to filter a signal by creating a series of peaks and troughs in the frequency spectrum. The position of the peaks and troughs of the waveform being affected is typically modulated by an internal low-frequency oscillator so that they vary over time, creating a sweeping effect. Phasers are often used to give a "synthesized" or electronic effect to natural sounds, such as human speech. Process The electronic phasing effect is created by splitting an audio signal into two paths. One path treats the signal with an all-pass filter, which preserves the amplitude of the original signal and alters the phase. The amount of change in phase depends on the frequency. When signals from the two paths are mixed, the frequencies that are out of phase will cancel each other out, creating the phaser's characteristic notches. Changing the mix ratio changes the depth of the notches; the deepest notches occur when the mix ratio is 50%. The def ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FM Synthesis
Frequency modulation synthesis (or FM synthesis) is a form of sound synthesis whereby the frequency of a waveform is changed by modulating its frequency with a modulator. The (instantaneous) frequency of an oscillator is altered in accordance with the amplitude of a modulating signal. FM synthesis can create both harmonic and inharmonic sounds. To synthesize harmonic sounds, the modulating signal must have a harmonic relationship to the original carrier signal. As the amount of frequency modulation increases, the sound grows progressively complex. Through the use of modulators with frequencies that are non-integer multiples of the carrier signal (i.e. inharmonic), inharmonic bell-like and percussive spectra can be created. FM synthesis using analog oscillators may result in pitch instability. However, FM synthesis can also be implemented digitally, which is more stable and became standard practice. Applications In synthesizers Digital FM synthesis (equivalent to phase ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhodes Piano
The Rhodes piano (also known as the Fender Rhodes piano) is an electric piano invented by Harold Rhodes, which became popular in the 1970s. Like a conventional piano, the Rhodes generates sound with keys and hammers, but instead of strings, the hammers strike thin metal tines, which vibrate next to an electromagnetic pickup. The signal is then sent through a cable to an external keyboard amplifier and speaker. The instrument evolved from Rhodes's attempt to manufacture pianos while teaching recovering soldiers during World War II. Development continued after the war and into the following decade. In 1959, Fender began marketing the Piano Bass, a cut-down version; the full-size instrument did not appear until after Fender's sale to CBS in 1965. CBS oversaw mass production of the Rhodes piano in the 1970s, and it was used extensively through the decade, particularly in jazz, pop, and soul music, as well by many rock artists. It was less used in the 1980s because of competi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roland MKS-80
The Roland MKS-80 Super Jupiter is a rack mount sound module version of the Roland Jupiter-6 and the Roland Jupiter-8 synthesizers. It is an 8-voice polyphonic analog synthesizer that was manufactured by Roland between 1984 and 1987. It is the only one of the MKS series of synthesizers to have analogue voltage-controlled oscillators (VCOs) instead of analogue digitally-controlled oscillators (DCOs). The voice architecture is almost identical to the Jupiter-6 synthesizer. The service manual states that "The module board of MKS-80 features the following in addition to that of JP-6, its brother module. 1) HPF. 2) Low boost circuit in the 2nd VCA. 3) DC supply current boost circuit (IC50)." In February 1985, Roland started producing a new revision of MKS-80, known as "Rev 5", with a new generation of both Roland VCO's, VCA's and filter. The Rev 5 filter was also used in JX-8P, JX-10 and MKS-70 synthesizers. Features The voice architecture of the MKS-80 is fully analog with 8 polyp ...

Roland JX-3P
The Roland JX-3P is a synthesizer produced by Roland Corporation of Japan from 1983–1985. The "3P" in its name refers to "Programmable Preset Polyphonic". It is notable as one of the company's first synthesizers (along with the Jupiter-6) to incorporate a MIDI interface. Features The JX-3P is a six-note polyphonic, 2 DCOs, 61 key synthesizer with sawtooth, 50 and 10% pulse waveforms, and a noise generator. It has 32 factory programs in ROM, and user memory for 32 programs. The JX-3P also features a built-in 128-step polyphonic sequencer that can be synchronized to external devices, such as drum machines, connected to its simple clock pulse input jack. MIDI clock synchronization is not supported. As one of the earliest MIDI devices, the JX-3P's MIDI implementation is basic, supporting only note on/off, pitch bend, hold, modulation and program change messages. Neither "System Exclusive" nor "Continuous Controllers" (CC) are implemented, so external patch storage or real-time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voltage Controlled Amplifier
A variable-gain (VGA) or voltage-controlled amplifier (VCA) is an electronic amplifier that varies its gain depending on a control voltage (often abbreviated CV). VCAs have many applications, including audio level compression, synthesizers and amplitude modulation. A crude example is a typical inverting op-amp configuration with a light-dependent resistor (LDR) in the feedback loop. The gain of the amplifier then depends on the light falling on the LDR, which can be provided by an LED (an optocoupler). The gain of the amplifier is then controllable by the current through the LED. This is similar to the circuits used in optical audio compressors. A voltage-controlled amplifier can be realised by first creating a voltage-controlled resistor (VCR), which is used to set the amplifier gain. The VCR is one of the numerous interesting circuit elements that can be produced by using a JFET (junction field-effect transistor) with simple biasing. VCRs manufactured in this way can be ...

19-inch Rack
A 19-inch rack is a standardized frame or enclosure for mounting multiple electronic equipment modules. Each module has a front panel that is wide. The 19 inch dimension includes the edges or ''ears'' that protrude from each side of the equipment, allowing the module to be fastened to the rack frame with screws or bolts. Common uses include computer servers, telecommunications equipment and networking hardware, audiovisual production gear, professional audio equipment, and scientific equipment. Overview and history Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack-mounted system, a rack-mount chassis, subrack, rack cabinet, rack-mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of or one rack unit or U (less commonly RU). The industry-standard rack cabinet is 42U tall; however, many data centers have racks taller than this. The term relay rack ...

Audio Mixer
A mixing console or mixing desk is an electronic device for mixing audio signals, used in sound recording and reproduction and sound reinforcement systems. Inputs to the console include microphones, signals from electric or electronic instruments, or recorded sounds. Mixers may control analog or digital signals. The modified signals are summed to produce the combined output signals, which can then be broadcast, amplified through a sound reinforcement system or recorded. Mixing consoles are used for applications including recording studios, public address systems, sound reinforcement systems, nightclubs, broadcasting, and post-production. A typical, simple application combines signals from microphones on stage into an amplifier that drives one set of loudspeakers for the audience. A DJ mixer may have only two channels, for mixing two record players. A coffeehouse's small stage might only have a six-channel mixer, enough for two singer-guitarists and a percussionist. A nightc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guitar Amplifier
A guitar amplifier (or amp) is an electronic amplifier, electronic device or system that strengthens the electrical signal from a Pickup (music technology), pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden speaker enclosure, cabinet. A guitar amplifier may be a standalone wood or metal cabinet that contains only the power amplifier (and preamplifier) circuits, requiring the use of a separate speaker cabinet–or it may be a ''combo'' amplifier, which contains both the amplifier and one or more speakers in a wooden cabinet. There is a wide range of sizes and power ratings for guitar amplifiers, from small, lightweight practice amplifiers with a single 6-inch speaker and a 10-watt amp to heavy combo amps with four 10-inch or four 12-inch speakers and a 100-watt amplifier, which are loud enough to use in a nightclub or bar performance. Guitar amplifiers can also modify ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
