Music and sound effects
One of the first products dedicated to music was the Bode Ring Modulator developed in 1961 by Harald Bode. Also in 1964, he developed the Bode Frequency Shifter, which produced a clearer sound by eliminating a sideband. These devices were designed to be controlled by voltage, compatible with modular synthesizer architecture also advocated by him, and these modules were licensed to R.A. Moog for their Moog modular synthesizers started in 1963–1964. In 1963, Don Buchla included an optional ring modulator in his first modular synthesizer, the Model 100. Also Tom Oberheim built a ring modulator unit for his friend Joseph Byrd in the late 1960s, and it became an origin of Oberheim ElectronicsMusic Modulator and Maestro Ring Modulator, one of the earliest ring modulator effect products for guitarists. The EMSVCS3, Synthi A, ARP 2600, Odyssey, Rhodes Chroma and Yamaha CS-80 synthesizers also featured built-in ring modulators.
