Moog And 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 is a machine that gives a musician far more control over the sound of the music. A synthesizer will have frequency generators that can generate specific frequencies.

Musicians who want to add a car horn sound effect to their music no longer have do to it by playing an audio tape; they can produce it with their synthesizers at the push of a button. Also unlike audio tapes, synthesizers can effortlessly produce sounds simultaneously such as a horn honk and a bird call.

The first synthesizers ever made were the analog synthesizers, breaking ground as early as 1876 by telephone prototype inventor Elisha Gray. Gray invented the first controllable single note oscillator when he discovered by mishap a self-vibrating electromagnetic circuit during his telephone experiments. Though the invention never broke into mainstream popularity, his "musical telegraph" could transport sounds via steel reeds through a telephone line, and set a milestone for others to follow.

Robert Moog, a brilliant scientist with a doctorate in engineering physics, greatly improved upon the synthesizer in the mid 1900s. He spent his entire career developing electronic music devices and, for that, he is widely known today as the father of the modern synthesizer.

Moog synthesizers have the capability of producing the sounds of a wide variety of traditional musical instruments, such as guitars, keyboards, horns, and drums. The Moog device uses piano as its controller.

Some of the first synthesizers were big and bulky and not very easy to move around. The design Moog came up with, along with ever-changing technology, paved the course for tinier and easy to carry devices. These tinier products make more sense for entertaining, especially if they have to be moved around. The synthesizers made today are extremely complicated units. They are made using computer chips and mother boards and use computer technology. The units are small and mostly self-sufficient, somewhat like computers now mad, and are moved about with ease.

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.
