The Buchla 259 Classic Reissue Programmable Waveform Generator is a meticulously crafted synthesiser module that reproduces the iconic sound of the original Model 259 while introducing modern enhancements, such as a 10-octave frequency range, fully analogue timbral circuitry, comprehensive voltage-controlled modulation, and a host of innovative features designed to expand its sonic versatility for professionals. Unparalleled Sound Quality and Expanded Range The reissue faithfully replicates the unmatched sound of the original Model 259 while overcoming limitations that once constrained its capabilities. The analogue timbral circuitry eliminates digital artefacts such as aliasing, ensuring pure and pristine sound output. This upgrade allows users to experience a multi-octave range of modulation and pitch control that pioneers of the original could only dream of. The oscillator design provides both a principal oscillator and a modulation oscillator, covering a frequency range of 27.5 Hz to 7040 Hz in normal operation, with an expanded low-frequency oscillator (LFO) mode spanning 0.25 Hz to 64 Hz. For precise pitch tracking, the quantised pitch mode enables notes from A1 to A9, making it a highly versatile tool for musical and experimental applications alike. Flexible Modulation and Advanced Controls The modulation oscillator offers three distinct waveshapes—sawtooth, square, and triangle—alongside dedicated sine and square wave outputs. Users gain extensive control over modulation through a modulation index parameter, CV input with attenuverter, and phase lock capability. Pitch modulation, amplitude modulation, and timbre modulation switches allow for further sonic exploration, enabling dynamic interactions between oscillators. Additionally, the 259 features frequency modulation inputs that support independent keyboard tracking and CV control, giving professionals granular control over harmonic content. Even and odd symmetry settings, along with harmonics controls featuring CV inputs, allow the sculpting of unique timbres. The phase lock input with adjustable gain further extends modulation possibilities, providing a cohesive and synchronised sound design workflow. Precision Tuning and Reliable Performance The Buchla 259 includes a 220 Hz autotune function with a low/high range switch, ensuring reliable frequency stability. Its 1.2V/octave tracking now spans an expansive 10 octaves with consistent performance, giving users unmatched precision and expressiveness in their compositions and sound designs. A Classic Reimagined for Modern Sound Design The Buchla 259 Classic Reissue Programmable Waveform Generator retains the distinctive character of its legendary predecessor while integrating modern advancements that enhance its reliability and creative potential. From analogue purity to extensive modulation options, this instrument stands as an essential tool for professionals seeking unparalleled sound design capabilities.
