Alexander Zolotov tells us that Virtual ANS is a software simulator of the unique Russian synthesizer ANS - photoelectronic microtonal/spectral musical instrument created by Russian engineer Evgeny Murzin from 1938 to 1958. The instrument was used by Stanislav Kreichi, Alfred Schnittke, Edison Denisov, Sofia Gubaidulina, Edward Artemiev and other Soviet composers and can be heard in Andrei Tarkovsky's movies Solaris, The Mirror, Stalker.
A spokesperson had this to say, "While the other similar programs are just fun toys, the Virtual ANS is a full-featured professional tool which allows you to create unusual, deep, atmospheric sounds. With this app you can draw a complete piece of music, or convert sound to image (sonogram) and then make some complex sonogram modifications. Actually the potential of the program has not been explored yet, so it (as well as PixiVisor) is more appropriate for people who are searching for something new, not afraid to experiment with sound."
The app is cross-platform and available for iOS, Android, Windows, Linux and OSX.
