Home Than has subdued a synthesizer of "Mug" of composers and executors of electronic music in 70th years? The answer to this question consists in the following: in a synthesizer of "Mug" all devices mutually were switched and coped the friend the friend that gave the chance thousand combinations. Besides, the section design of the given synthesizer allowed to do its as much as big and the quantity of combinations grew to astronomical sizes, but, despite it, management of a synthesizer remains extremely simple, and execution occurred on the usual keyboard where all electronic blocks and which freely were switched and was operatively reconstructed in any elite звукоряды, frets and т. д. In "Muge" possibility has been provided in advance to program various combinations (any complexities) and to include them at any moment of execution. In those days this device, however as well as the majority of synthesizers of other systems, continuously blocked звуковысотную a scale (close to borders of our sound threshold) from 10 hertz and more low, to 20 kilohertz. Fans of music could estimate huge possibilities of "Muga" as imitating known traditional tools, on вениловому to a disk "Switched Bach" - Uoltera Carlos's record ("Switched On Bach"-Columbia Records MS 7194). And film studios, radio and television centres widely used Robert Muga's synthesizers for illustrative effects. Besides this device became the first performing tool of electronic music (the first live performance "Mugov" has taken place on August, 28th, 1969) and the composer again обрeл lost, it seemed for ever, a role of the composer-executor-virtuoso, причeм performing possibilities of "Muga" (in comparison with other synthesizers of the end 60 - the beginnings of 70th years) were so great that actions it were limited only by intuition and an ingenuity of the composer. Except that "Mug" had an input for transformation through any concrete material all its devices (from music, noise, nature sounds etc.) which could be скоммутирован on the keyboard and executed already on it. Also in a design of "Muga" possibility of connection of the computer has been provided.
