Photoelectric composition machine (named from the initials of Aleksandr Nikolayevich Skryabin) developed from about 1950 in Moscow by Evgeny Murzin (c1913–70). The idea for such a machine dated back to 1938, when Murzin visited the acoustician Boris Yankovsky, who had collaborated in experiments on graphic sound with Arseny Avraamov and soon afterwards worked with Evgeny Sholpo in Leningrad on his composition machine, the Variophon. The ANS was remarkably close to the concept of the Mechanical Orchestra, a sound synthesis machine proposed by Sholpo in 1917. The ANS was based on a set of optical sine wave oscillators, adjusted on fixed frequencies, forming a discrete scale, and covering the whole audible range with very small intervals between successive pitches.
World War II delayed Murzin’s work, so the first model of the ANS was not completed until 1957. It was installed in an improved form in 1959 at the Skryabin Museum in Moscow, where it became the basis of the Soviet Union’s first electronic music studio (in ...
