Evolver (synthesizer)
The Evolver is an analog-digital hybrid synthesizer designed by Dave Smith and manufactured by Dave Smith Instruments. It was first released as a desktop version in 2002, then later a 37-key keyboard bearing the same synth engine as the Evolver desktop was also released. A polyphonic version of the Evolver, dubbed the Poly Evolver, was released in 2004 as a rackmount version, then a 61-key keyboard version of the Poly Evolver was released in 2005. The Evolvers were replaced by new high end models, the Prophet 12 and the Pro 2. History Smith worked on a number of synthesizers in the past, such as the revolutionary Prophet 5, the Korg Wavestation (a direct descendant of the Prophet VS), and the first professional software synthesizer, "Reality". After helping Roger Linn on his line of AdrenaLinn guitar effects pedals, he got interested in hardware again and eventually decided to start producing a new line of hardware synthesizers, partly because of seeing how soft synths are now ea ...

Subtractive Synthesis
Subtractive synthesis is a method of sound synthesis in which partials of an audio signal (often one rich in harmonics) are attenuated by a filter to alter the timbre of the sound. While subtractive synthesis can be applied to any source audio signal, the sound most commonly associated with the technique is that of analog synthesizers of the 1960s and 1970s, in which the harmonics of simple waveforms such as sawtooth, pulse or square waves are attenuated with a voltage-controlled resonant low-pass filter. Many digital, virtual analog and software synthesizers use subtractive synthesis, sometimes in conjunction with other methods of sound synthesis. Examples of subtractive synthesis A human example The basis of subtractive synthesis can be understood by considering the human voice; when a human speaks, sings or makes other vocal noises, the vocal folds act as an oscillator and the mouth and throat as a filter. Consider the difference between singing "oooh" and "aaah" , a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feedback
Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to ''feed back'' into itself. The notion of cause-and-effect has to be handled carefully when applied to feedback systems: History Self-regulating mechanisms have existed since antiquity, and the idea of feedback had started to enter economic theory in Britain by the 18th century, but it was not at that time recognized as a universal abstraction and so did not have a name. The first ever known artificial feedback device was a float valve, for maintaining water at a constant level, invented in 270 BC in Alexandria, Egypt. This device illustrated the principle of feedback: a low water level opens the valve, the rising water then provides feedback into the system, closing the valve when the required level is reached. This then reoccurs in a circular fashion as the water level fluctuates. Centrifugal governors were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring Modulation
In electronics, ring modulation is a signal processing function, an implementation of frequency mixing, in which two signals are combined to yield an output signal. One signal, called the carrier, is typically a sine wave or another simple waveform; the other signal is typically more complicated and is called the input or the modulator signal. A ring modulator is an electronic device for ring modulation. A ring modulator may be used in music synthesizers and as an effects unit. The name derives from the fact that the analog circuit of diodes originally used to implement this technique takes the shape of a ring: a diode ring. The circuit is similar to a bridge rectifier, except that instead of the diodes facing left or right, they face clockwise or counterclockwise. Ring modulation is quite similar to amplitude modulation, with the difference that in the latter the modulator is shifted to be positive before being multiplied with the carrier, while in the former the unshifted ...

Oscillator Sync
Oscillator sync is a feature in some synthesizers with two or more VCOs, DCOs, or "virtual" oscillators. As one oscillator finishes a cycle, it resets the period of another oscillator, forcing the latter to have the same base frequency. This can produce a harmonically rich sound, the timbre of which can be altered by varying the synced oscillator's frequency. A synced oscillator that resets other oscillator(s) is called the master; the oscillators which it resets are called slaves. There are two common forms of oscillator sync which appear on synthesizers: Hard Sync and Soft Sync. According to ''Sound on Sound'' journalist Gordon Reid, oscillator sync is "one of the least understood facilities on any synthesizer". Hard Sync The leader oscillator's pitch is generated by user input (typically the synthesizer's keyboard), and is arbitrary. The follower oscillator's pitch may be tuned to (or detuned from) this frequency, or may remain constant. Every time the leader oscillator's c ...

Oscillators
Oscillation is the repetitive or periodic variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. Familiar examples of oscillation include a swinging pendulum and alternating current. Oscillations can be used in physics to approximate complex interactions, such as those between atoms. Oscillations occur not only in mechanical systems but also in dynamic systems in virtually every area of science: for example the beating of the human heart (for circulation), business cycles in economics, predator–prey population cycles in ecology, geothermal geysers in geology, vibration of strings in guitar and other string instruments, periodic firing of nerve cells in the brain, and the periodic swelling of Cepheid variable stars in astronomy. The term ''vibration'' is precisely used to describe a mechanical oscillation. Oscillation, especially rapid oscillation, may be an undesirable phenomenon in proce ...

Software Protection Dongle
A software protection dongle (commonly known as a dongle or key) is an electronic copy protection and content protection device. When connected to a computer or other electronics, they unlock software functionality or decode content. The hardware key is programmed with a product key or other cryptographic protection mechanism and functions via an electrical connector to an external bus of the computer or appliance. In software protection, dongles are two-interface security tokens with transient data flow with a pull communication that reads security data from the dongle. In the absence of these dongles, certain software may run only in a restricted mode, or not at all. In addition to software protection, dongles can enable functions in electronic devices, such as receiving and processing encoded video streams on television sets. Etymology The Merriam-Webster dictionary states that the "First known use of dongle" was in 1981 and that the etymology was "perhaps alteration of dangl ...

Roger Linn
Roger Curtis Linn is an American designer of electronic musical instruments and equipment. He is the designer of the LM-1, the first drum machine to use samples, and the MPC sampler, which had a major influence on the development of hip hop. Roger Linn is also a member of the Dead Presidents Society, a group of innovators in the field of electronic music. Linn Electronics In 1979, Roger Linn and Alex Moffett founded ''Linn Moffett Electronics'' (soon to be renamed ''Linn Electronics'') to develop Linn's design for a drum machine that uses digital samples. It would be called ''LM-1'' for Linn/Moffett/1. Moffett left the company in 1982. Linn used his new drum machine and performed with Leon Russell on his album Life and Love in 1979. LM-1 In 1980, Roger Linn released the world's first drum machine to use digital samples, the LM-1 Drum Computer. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Synthesizer
A software synthesizer or softsynth is a computer program that generates digital audio, usually for music. Computer software that can create sounds or music is not new, but advances in processing speed now allow softsynths to accomplish the same tasks that previously required the dedicated hardware of a conventional synthesizer. Softsynths may be readily interfaced with other music software such as music sequencers typically in the context of a digital audio workstation. Softsynths are usually less expensive and can be more portable than dedicated hardware. Types Softsynths can cover a range of synthesis methods, including subtractive synthesis (including analog modeling, a subtype), FM synthesis (including the similar phase distortion synthesis), physical modelling synthesis, additive synthesis (including the related resynthesis), and sample-based synthesis. Many popular hardware synthesizers are no longer manufactured but have been emulated in software. The emulation can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Korg Wavestation
The Korg Wavestation is a vector synthesis synthesizer first produced in the early 1990s and later re-released as a software synthesizer in 2004. Its primary innovation was Wave Sequencing, a method of multi-timbral sound generation in which different PCM waveform data are played successively, resulting in continuously evolving sounds. The Wavestation's "Advanced Vector Synthesis" sound architecture resembled early vector synths such as the Sequential Circuits Prophet VS. Designed as a "pure" synthesizer rather than a music workstation, it lacked an on-board song sequencer, yet the Wavestation, unlike any synthesizer prior to its release, was capable of generating complex, lush timbres and rhythmic sequences that sounded like a complete soundtrack by pressing only one key. – see "The Wavestation Family" – see heading "1990" & "Milestone—The Wavestation Family" ''Keyboard Magazine'' readers gave the Wavestation its "Hardware Innovation of the Year" award, (see also c ...

Prophet 5
The Prophet-5 is an analog synthesizer manufactured by the American company Sequential. It was designed by Dave Smith and John Bowen in 1977, who used microprocessors, then a new technology, to create the first polyphonic synthesizer with fully programmable memory. This allowed users to store sounds and recall them instantly rather than having to reprogram them manually; whereas synthesizers had once created unpredictable sounds, the Prophet-5 moved synthesizers to producing "a standard package of familiar sounds". Between 1978 and 1984, about 6,000 units were produced across three revisions. In 1981, Sequential released a 10-voice, double-keyboard version, the Prophet-10. Sequential introduced new versions in 2020, and it has been emulated in software synthesizers and hardware. The Prophet-5 has been widely used in popular music and film soundtracks. Development The Prophet-5 was created in 1977 by Dave Smith and John Bowen at Sequential Circuits. At the time, Smith had a ...

Prophet 12
In religion, a prophet or prophetess is an individual who is regarded as being in contact with a divine being and is said to speak on behalf of that being, serving as an intermediary with humanity by delivering messages or teachings from the supernatural source to other people. The message that the prophet conveys is called a prophecy. Claims of prophethood have existed in many cultures and religions throughout history, including Judaism, Christianity, Islam, ancient Greek religion, Zoroastrianism, Manichaeism, Hinduism , and many others. Etymology The English word ''prophet'' is the transliteration of a compound Greek word derived from ''pro'' (before/toward) and ''phesein'' (to tell); thus, a προφήτης (''prophḗtēs'') is someone who conveys messages from the divine to humans, including occasionally foretelling future events. In a different interpretation, it means advocate or speaker. In Hebrew, the word נָבִיא (''nāvî''), "spokesperson", traditionally tra ...
