In the early 1960s, the advent of the transistor and miniaturization mark a milestone in the history of the synthesizer. The transistor mark the birth of the modern synthesizer. During this decade the (relative) reduction of cost of machinery promotes wider dissemination of the synthesizer. During 1964 two powerful models are developed simultaneously, combining the functions of processing and synthesis of sound:
The first model is called Synket created by engineer Paolo Ketoff. He is a pioneer in integrating the basic elements that will be taken up subsequently in most synthesizers. Transistor, it has several oscillators, filters affecting stamps and a system of frequency modulation.
The second model is an instrument controlled by keyboard, composed of independent modules and voltage controlled (voltage control). It was developed by an engineer whose models to come, will be much written, it is Robert Moog. At the same time, another American, Donald Buchla, also the idea of using modules interconnected.
In 1969, the famous synthesizer VCS-3 developed by UK-based EMS provides for the first time not separate modules, designed in a single portable unit. It marks the beginning of the models pre-wired modules, using small cards that were inserted in a matrix linking the various modules. This synthesizer offered enormous possibilities of sound creation.
A little over ten years will have only enough to pass laboratory prototypes, heavy and bulky, facilities producing instruments transportable on an industrial scale. Marks appear first in the United States, Japan and then offer more devices and more efficient and simple to use. Synthesizers similar soon to consumer goods. Marketing is booming. The early craftsmen synthesizer quickly become marginalized in favor of big brands.
