Harness Unpredictability
While the 267e and the 266e are both built on utilizing signal unpredictability, the 266e prioritizes control over managing the unpredictability, whereas the 267e focuses on refining the output. This 2-part module features its own engine of improbability, with two distinct voltage sources. For both, the probable rate of change can be continuously varied or voltage controlled. In a notable deviation from its sibling, pulses can actually sample these voltages, allowing for the possibility of random voltages with wide time correlations. The “random” knob modifies the overall range of possible frequencies as a manner of deviation from the source frequency. For noise generation, the 267e has three flavors of noise: white noise, musically flat noise, and integrated white noise. These outputs vary with their spectral responses to sound, balancing toward high end (3dB/octave), flat (equal energy/octave), and low end (-3dB/octave). Down below, a dual bandpass filters are designed to create filtered noise via voltage control of pitch, bandwidth, and modulation index parameters, with their inputs normalized to the module’s flat noise source without an external input. To bring wild layer of color to your Buchla system, Sweetwater synthesists agree that the 267e Uncertainty Source/Dual Filter Module is a must.

Buchla: the crossroads of sonic excellence and game-changing technology
The name Buchla is synonymous with some of the most compelling, convention-breaking technology to emerge in the musical spheres of the mid-20th-century’s electronic awakening. A pioneer of electronic music and instrument design, Don Buchla founded his namesake company in the 1960s, following the success of a modular electronic music system that was commissioned by composers on a Rockefeller Foundation grant. For the next 50 years, Don lived on the bleeding edge of electronic music synthesis. He incorporated uncommon coding languages, touch- and pressure-sensitive surfaces, and spatial location modulation, eventually innovating for the likes of Oberheim, CBS, Zeta Music, E-Mu Systems, and Moog. Meanwhile, he also dedicated himself to make good on MIDI’s promise of the 1980s to be more than just a piano keyboard controller. By the 2000s, Don introduced his magnum opus with the 200e, a love letter to a half century of unparalleled innovation in modular and analog synthesis. Today, Buchla U.S.A. works diligently to uphold Don’s rich legacy and provide his classic designs alongside new iterations of products that are “designed to introduce the unique world of Buchla synthesis to a whole new generation of electronic music makers.”
Buchla 267e Uncertainty Source/Dual Filter Module Features:
- Voltage control of nearly all parameters allows for hyper-modular integration
- Varied models of randomness provide opportunities to shape and fine-tune without sacrificing the core qualities of unpredictability
- Pot and knob information can be stored for preset recall
- Dual bandpass filter delivers countless options for noise creation and modification
Note: Storing and recalling presets requires use of the “remote enable” function, which is only available with the inclusion of a 225e or 206e in your Buchla system. Please contact your Sweetwater Sales Engineer with any questions or concerns.
