An analog synthesizer is an instrument that uses analog circuits and analog computer techniques to create an electronic sound. A very specific form of this synthesizer was the analog vocoder, based on equipment developed for speech synthesis. This popular musical instrument can be used both as the generation sound and a sound processing system.
A brief history of analog synthesizers
Trautonium is the first synthesizer, using a variety valve technology and electro mechanics. It was invented in 1928. Early versions of this instrument used the technology, which is derived from electronic equipment analogue and laboratory test equipment. These were mostly replaced by digital synthesizers and samplers on the mid-1980s. In 1978, the first microprocessor controlled system was created and introduced.
The various modules of analog synthesizers
They were found in different modules, when that was first introduced. Because many of these modules sound input signals and processed them, an analog synthesizer could generate and process sound simultaneously. Here are some of the modules, which are commonly found in an analog synthesizer.
VCO
Oscillator Voltage Controlled is the most widely used source module. It generates a stable signal at a preset pitch. The signal is usually available in a variety of waveforms that are selected by connecting patch.
VCA
Voltage controlled amplifier changes the amplitude of a signal and generally have a very wide frequency response.
FCR
Voltage Controlled Filters. Most of the flexibility of an analog synthesizer sound comes from filters.
About Generators
An envelope generator produces and controls the voltage that rises and falls according to a voltage command. About Generators also voltage control of some parameters, delay start and end of pulse release.
LFO
LFO has an output waveform low frequency and the output is usually a sine or triangle wave. Also used as a control voltage to some other modules. For example, you can use to modulate the frequency of a VCO.
Ring Modulators
When two signals are combined into a ring modulator, gives a distorted frequency.
Sequencers
Preprogrammed sequence allows a melody to a set of buttons.
Reverb Units
Sound Mixers
All synths analog sound mixers have some simple to allow the combination of signals.
Many people and companies making this popular instrument. However, the most famous and most widely used of these are
A Moog synthesizer
A modular Emu
A Synton
A homemade machine
Conclusion
Devices synthesizers have developed themselves in time to make a permanent place in the world of synthesizers. Although the digital synthesizers are the most widely used, professionals and sound technicians still prefer analog synthesizers now.
After the introduction of digital synthesizers of the musicians who do not want to spend much money for these systems, began using the analog. This policy allowed to increased demand for analog marks the mid-1990s. It became increasingly popular because of its unique modules, which consisted of a series independent electronic modules connected by patch cables.
