The Buchla 666 Modular Electronic Music System And Star Destroyer, sometimes referred to as "The Forbidden Buch" is a never-announced, never-built, and never made commercially available analog synthesizer and sun-destroying superweapon rumored to have been in production at Buchla Electronic Musical Instruments during the late 1970s.
Following the success of the Music Easel, and living in fear of retribution from extra-terrestrial beings for the successful Apollo missions conducted by NASA, Don Buchla began looking into the potential military applications of saw waves in a war against aliens. In journals of the era, Buchla wrote of the process "The idea is to generate a vibration powerful enough to reach the plasma inside of a star, triggering a chain reaction there, leading to the star's implosion." Taking the 300 series as a base, he reorganized the modules so as to concentrate harmonics and maximize its ritualistic potential during use. Early testing for the 666 showed promise, leading to the discovery of several new keys, the most famous of which being Tropical B, and Q Major.
Later testing, and "The Incident"
Teaming up with para-acoustic occultist Jameson St. Violence, Buchla took to the Colorado desert for further rounds of testing. Very little is known about what took place during the tests. Based on the available information, as well as St. Violence's account of the events, it is believed that Don Buchla succesfully synthesized a category 5 harmonic event, manifesting a vision of a reality, parallel to the Immaterial Plane, whose nature was so horrific to Buchla that he immediately started bashing the Model 666 with a nearby rock. All documentation related to the Buchla 666 was subsequently either lost or destroyed. Shortly thereafter, Buchla announced he would devote his fortune to the founding of an organization, "whose purpose shall be to watch over every event in synthesizing, so as to ensure the integrity of our reality against the misuse of fundamental ontological harmonics." Following the signing of the Zurich Charter, Buchla became a founding member of the Bureau International D'Etude des Harmonies Ontologiques (BIDHO).
After the Zurich Charter established the notion of "Synth Crime Against Reality", the field of para-acoustics faced a sudden decline, and synth players everywhere moved away from exploring the alterative potential of their synths, instead choosing to begin laying the bases for what would become post-punk, and later New Wave. Knowledge of the Buchla 666 passed into urban legend, where it remained for several years, until a recent lawsuit revealed the existence of lost Don Buchla manuscripts, confirming in writing that an analog synth and star-destroyer was indeed at one point in development. Rumors of the 666's power began escalating, launching a new movement among industrial and harsh noise enthusiasts looking for new sounds through the damaging of reality via Satanic synth rituals. Prominent synth players of the new para-acoustics movement include Hugo Granola, Phoebe Cloth, and Ron Monstera of the Seattle Garages, who has claimed to be on a quest for a chord capable of breaking the flow of time.
