Theremin is an electronic musical instrument controlled without physical contact by the thereminist (performer). It is named after the Westernized name of its Soviet inventor, Léon Theremin (Лев Термéн), who patented the device in 1928.
FPGA Theremin project is attempt to build modern digital theremin with rich set of features.
