The History Of Digital Synthesizers

By Charlie Michaels

The creation of the musical synthesizer transformed the sound enjoyment all around the world. An entertainer who wished to reproduce a certain type of sound before a live audience had to depend on conventional recordings. Nowadays, that can be done and produced live giving the performer a choice of thousands of sounds, notes and frequencies at his fingertips.

A synthesizer produces sound by doing just what it says it does: it "synthesizes." It works by electronically combining different frequencies to produce thousands of different sounds.

It has the capability to manipulate various parameters of the built-in sounds. It is not that these are used only for techno sounds, these instruments contain many melody and percussion sounds as well. Thus it can produce multiple sounds at a time.

Elisha Gray invented the first known synthesizer sometime in the latter part of the 1800s. He is mostly renowned for some of his other work: the telegraph and one of the first forms of the telephone. Gray led the way in electronics and was a future thinker in many ways. Although his premiere device was thought to be a little elementary by todays values, it cleared the path for models we have today.

Robert Moog is credited as the inventor who made improvements to the synthesizer. A genius of a scientist, he got his Ph.D. in engineering physics in the middle of the 1900s. During his entire career he worked with and developed electronic sound systems, instruments and other items. Many people think of Moog as the father of todays synthesizer.

Moog's synthesizer was at the head of the line in using a piano keyboard to control it. Prototypes that came before had used switches, dials and buttons. For that reason, they are compared to the pianos and electronic keyboards produced now. But they can be controlled by other methods. One example of that is a Guitar synthesizer.

With the invention of technology, early synthesizers were replaced by modern synthesizer. In the late 1960s and throughout the 1970s the voltage-controlled analogue synthesizer was standard. They were huge and occupied enough space. Now the digital synthesizer is being used which is a highly sophisticated instrument that can be transported easily and thus not occupy enough space.

A keyboard synthesizer is a piano alternative that creates sound through electrical currents which is still common among musicians. A software synthesizer, common among musicians, also known as a softsynth or virtual instrument is a computer program for digit audio generation. Saxophone-style synthesizer is also being used.
