The Buchla Classic Reissue of the Source of Uncertainty Model 266 provides a fruitful source of musical unpredictability and sonic exploration.
The reissue module received a refresh from Roman Filippov of Black Corporation and is divided into several sections, each of which perform a unique function.
Three type of noise are available, with corresponding dedicated outputs. White noise is electrically flat, but acoustically balanced toward the high end of the spectrum ( 3 db/octave). Integrated white noise has a low spectral bias (-3 db/octave). Musically flat noise has a flat spectrum (constant energy per octave) and is a particularly useful source for subsequent processing.
Fluctuating Random Voltages are continuously variable, with voltage control of bandwidth over an extensive range of .05Hz to 50Hz, making possible changes that vary from barely perceptible movement to rapid fluctuation.
Quantized Random Voltages change upon receiving pulses, with the number of states being voltage-controllable.
In addition, it includes a Stored Random Voltages section, a voltage controlled Integrator and Sample-and-Hold-functionality.
Pioneering synthesizer design since the mid 1960s with Morton Subotnick and the San Francisco Tape Center, Don Buchla has been responsible for the invention of the sequencer, low pass gate, random voltage generators and the complex oscillator, among others. Shortly before his passing in 2016, his rights were acquired by Australian holding company BEMI (2012-2017) and since 2018 is operated by Eric Fox of Buchla USA, based in Minnesota. Buchla USA offers the whole 200e series catalog and boats, as well as the iconic Music Easel.
