Buchla 266e Source of Uncertainty

The Buchla 266e Source of Uncertainty is a voltage-controlled random voltage generator module designed by Don Buchla. It is a part of the Buchla 200e series of modular synthesizers. The module is used to generate random voltages, which can be used to create unpredictable and chaotic sounds. It has two main features: a random voltage generator and a voltage-controlled random voltage generator. The random voltage generator produces a random voltage that can be used to modulate other modules. The voltage-controlled random voltage generator allows the user to control the randomness of the voltage by adjusting the voltage control knob. The module also has a built-in clock, which can be used to synchronize the random voltage generator with other modules. The module has been used by many artists, including Aphex Twin, Autechre, and Squarepusher.
