Wikipedia : One of the earliest musical instruments utilizing a ring modulator may be the Melochord (1947) built by Harald Bode. It was a two-tone melody keyboard instrument with foot controllers and later added a second keyboard for timbre control, featuring a white-noise generator, envelope controller, formant filters and ring modulators for harmonics. The early Melochord was extensively used by Werner Meyer-Eppler in the early days of the electronic music studio at Bonn University.

This is a Eurorack packaging of the Polivoks Generator circuit, authorized by the instrument inventor Vladimir Kuzmin. The exponential converter and temperature compensation circuits use original NOS Soviet integrated circuits. The hard sync is very sharp and the distortion on the triangle output is nice.
