Unleash the essence of sonic unpredictability with the Buchla 267e Uncertainty Source / Dual Filter. This avant-garde modular synthesizer module is crafted for musicians and sound designers who thrive on pushing the boundaries of auditory exploration. Unlike its sibling, the 266e, the 267e emphasizes refined output, delivering a symphony of randomness that can be harnessed or let loose, depending on your creative whims.

The 267e features two distinct voltage sources with continuously variable or voltage-controlled change rates. A standout element is its ability to sample voltages using pulses, enabling a spectrum of random voltages with extended time correlations. The module also offers three noise flavors: white noise, musically flat noise, and integrated white noise, each with unique spectral responses, allowing for a gradient of tonal character from high to low frequencies.

Dive deeper into sound manipulation with the dual bandpass filters. These are not just any filters; they are designed with voltage control over pitch, bandwidth, and modulation index, all normalized to the module’s flat noise source. This setup offers a palette of filtered noise options that can be sculpted to your liking. Whether you're looking to add a touch of chaos or a layer of harmonic complexity, the 267e is your gateway to new sonic landscapes.

Key Features:

• Voltage control over nearly all parameters for seamless modular integration
• Multiple models of randomness for versatile sound shaping
• Preset recall capability for pot and knob settings
• Dual bandpass filters for dynamic noise creation and modification
