ANS synthesizer

Optically controlled music instrument

The ANS synthesizer is a photoelectronic musical instrument designed by the Soviet engineer Evgeny Murzin and completed in 1957, named after the composer Alexander Nikolayevich Scriabin. It generates sound from images: marks made on glass plates coated with opaque mastic are read optically and resynthesized as continuous additive tones. A single instrument was built and was famously used by composers such as Edward Artemiev, including for Soviet film scores.
