Prophet '08
The Prophet '08 is a polyphonic analog synthesizer released by Dave Smith Instruments (DSI) in 2007. As with DSI's other instruments, the Prophet '08 uses analog subtractive synthesis. Similar in functionality to the renowned Sequential Circuits Prophet-5 popularized in the 1970s (also designed by Dave Smith), the Prophet '08 has an all analog signal path; however its envelopes are generated digitally. In 2017, the Prophet '08 was superseded by the Prophet Rev2, which is available in 8-voice and 16-voice versions as well as keyboard and module variants. The Prophet Rev2 added waveshape modulation, improved onboard effects, a sub oscillator and a polyphonic sequencer. Sound architecture The Prophet '08 is an eight-voice analog synthesizer featuring all-analog audio paths with digital parameter control. It offers three playing modes: uniform eight-voice, a split mode dividing the keyboard between two different sounds, and a stacked mode for layered four-voice textures. Each voi ...

Envelope (music)
In sound and music, an envelope describes how a sound changes over time. For example, a piano key, when struck and held, creates a near-immediate initial sound which gradually decreases in volume to zero. An envelope may relate to elements such as amplitude (volume), frequency (with the use of filters) or pitch. Envelope generators, which allow users to control the different stages of a sound, are common features of synthesizers, samplers, and other electronic musical instruments. The most common envelope generator is controlled with four parameters: attack, decay, sustain and release (ADSR). Envelope generators Development The envelope generator was created by the American engineer Robert Moog, the creator of the Moog synthesizer, in the 1960s. The composer Herbert Deutsch suggested Moog find a way to articulate his synthesizer so notes did not simply trigger on and off. Moog wired a doorbell button to the synthesizer and used a capacitor to store and slowly release ... [...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 c ...

Voltage-controlled Filter
A voltage-controlled filter (VCF) is an electronic filter whose operating characteristics (primarily cutoff frequency) can be set by an input control voltage. Voltage-controlled filters are widely used in synthesizers. A music synthesizer VCF allows its cutoff frequency, and sometimes its Q factor (resonance at the cutoff frequency), to be continuously varied. The filter outputs often include a lowpass response, and sometimes highpass, bandpass or notch responses. Some musical VCFs offer a variable ''slope'' which determines the rate of attenuation outside the bandpass, often at 6 dB/octave, 12 dB/octave, 18 dB/octave or 24 dB/octave (one-, two-, three- and four-pole filters, respectively). In modular analog synthesizers, VCFs receive signal input from signal sources, including oscillators and noise, or the output of other processors. By varying the cutoff frequency, the filter passes or attenuates partials of the input signal. In some popular elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prophet-5
The Prophet-5 is an analog synthesizer manufactured by the American company Sequential (company), Sequential. It was designed by Dave Smith (engineer), Dave Smith and John S. Bowen (sound designer), John Bowen in 1977. It was the first Polyphony and monophony in instruments, polyphonic synthesizer with fully Computer memory, programmable memory. Before the Prophet-5, synthesizers required users to adjust controls to change sounds, with no guarantee of exactly recreating a sound. Sequential used Microprocessor, microprocessors to allow users to recall sounds instantly rather than having to recreate them manually. The Prophet-5 facilitated a move from synthesizers creating unpredictable sounds to producing "a standard package of familiar sounds". The Prophet-5 became a market leader and was widely used in popular music and film soundtracks. In 1981, Sequential released a 10-voice, double-keyboard version, the Prophet-10. Sequential introduced new versions in 2020, and it has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Analog Synthesizer
An analog synthesizer () is a synthesizer that uses Analogue electronics, analog circuits and analog signals to generate sound electronically. The earliest analog synthesizers in the 1920s and 1930s, such as the Trautonium, were built with a variety of vacuum tube, vacuum-tube (thermionic valve) and electro-mechanical technologies. After the 1960s, analog synthesizers were built using operational amplifier (op-amp) integrated circuits, and used potentiometers (pots, or variable resistors) to adjust the sound parameters. Analog synthesizers also use low-pass filters and high-pass filters to modify the sound. While 1960s-era analog synthesizers such as the Moog synthesizer, Moog used a number of independent electronic modules connected by patch cables, later analog synthesizers such as the Minimoog integrated them into single units, eliminating patch cords in favour of integrated signal routing systems.

Polyphonic Synthesizer
Polyphony is a property of musical instruments that means that they can play multiple independent melody lines simultaneously. Instruments featuring polyphony are said to be polyphonic. Instruments that are not capable of polyphony are monophonic or paraphonic. An intuitively understandable example for a polyphonic instrument is a (classical) piano, on which the player plays different melody lines with the left and the right hand - depending on music style and composition, these may be musically tightly interrelated or may even be totally unrelated to each other, like in parts of Jazz music. An example for monophonic instruments is a trumpet which can generate only one tone (frequency) at a time, except when played by extraordinary musicians. Synthesizer Monophonic A monophonic synthesizer or ''monosynth'' is a synthesizer that produces only one note at a time, making it smaller and cheaper than a polyphonic synthesizer which can play multiple notes at once.

United States Dollar
The United States dollar (Currency symbol, symbol: Dollar sign, $; ISO 4217, currency code: USD) is the official currency of the United States and International use of the U.S. dollar, several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish dollar, Spanish silver dollar, divided it into 100 cent (currency), cents, and authorized the Mint (facility), minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The U.S. dollar was originally defined under a bimetallism, bimetallic standard of (0.7734375 troy ounces) fine silver or, from Coinage Act of 1834, 1834, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed. The U.S. dollar became an important intern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
