A Triumvirate of Textures
As with all things Buchla, the 291e is perfect for sound modeling and audio textures, built centrally around the operation and modulation of three voltage-controlled bandpass filters. Each of the three filters is comprised of an amplitude, a center frequency, and a bandwidth parameter that can all be independently controlled through CV and externally applied signals. Moreover, depending on the input choices, these three filters can operate as parallel channels or totally independently. The filters operate like a sequencer with eight total stages; each stage has parameters that you can set with time variation at each stage ranging from .01 to 10 seconds. Advanced editing options, voltage-controlled parameters, and various “all” ports (for managing all inputs or channels) create an abundance of sonic opportunities that Sweetwater synth enthusiasts consider more than a worthy addition to any Buchla system.
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.”
