- Q1970809 abstract "The ANS synthesizer is a photoelectronic musical instrument created by Russian engineer Evgeny Murzin from 1937 to 1957. The technological basis of his invention was the method of graphical sound recording used in cinematography (developed in Russia concurrently with USA), which made it possible to obtain a visible image of a sound wave, as well as to realize the opposite goal—synthesizing a sound from an artificially drawn sound spectrogram.In this case the sine waves generated by the ANS are printed onto five glass discs using a process that Murzin (an optical engineer) had to develop himself. Each disc has 144 individual tracks printed onto it, for a total of 720 microtones (discrete pitches), spanning 10 octaves. This yields a resolution of 1/72 octave (16.67 cents). The modulated light from these wheels is then projected onto the back of the synthesizer's interface. These are arranged in a continuous swath vertically, with low frequencies at the bottom and high frequencies at the top.The user interface consists of a glass plate covered in non-drying opaque black mastic, which constitutes a drawing surface upon which the user makes marks by scratching through the mastic, and therefore allowing light to pass through at that point. In front of the glass plate sits a vertical bank of twenty photocells that send signals to twenty amplifiers and bandpass filters, each with its own gain adjust control. It is akin to a ten-octave equalizer with two knobs per octave. The ANS is fully polyphonic and will generate all 720 pitches simultaneously if required (a vertical scratch would accomplish this).The glass plate can then be scanned left or right in front of the photocell bank in order to transcribe the drawing directly into pitches. In other words, it plays what one has drawn, similar to how a score is written. This process can be aided with a gear-motor drive (similar to an engineering lathe) or it can be moved manually. The scan speed is adjustable down to zero. The speed at which the score scans has no relation to pitch but serves only as a means of controlling duration.Murzin named his invention in honour of the composer Alexander Nikolayevich Scriabin (ANS): Scriabin (1872–1915) was an occultist, theosophist, and early exponent of color-sound theories in composition. The synthesizer was housed in the electronic-music studio situated above the Scriabin Museum (just off of the Arbat in central Moscow) before moving to the basement of the central university on the corner of Bolshaya Nikitskaya. It was saved from the scrapheap thanks to Stanislav Kreichi, who persuaded the university to look after it.The ANS was used by Stanislav Kreichi, Alfred Schnittke, Edison Denisov, Sofia Gubaidulina, and other Soviet composers. Edward Artemiev wrote many of his scores of the movies of Andrei Tarkovsky with the help of the ANS. Notably is Artemiev's score of Tarkovsky's Solaris in which the ANS was used to abstract, sci-fi effect akin to ambient music.After several years at the Theremin Center, the ANS (there is only one—the original was destroyed and this is the improved version) is now located in the Glinka State Central Museum of Musical Culture in Moscow.".
