Buchla 267e Uncertainty Source

It combines noise sources, dual random voltage sources, and two-channel filter.

The 267e combines noise sources, dual random voltage sources, and a simple two-channel filter into a single module.

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.

Dual Random Voltage sources are provided. Each is continuously variable, with voltage control of bandwidth over the range of .05Hz to 50Hz, making possible changes that vary from barely perceptible movement to rapid fluctuation. Applied pulses sample these voltages, providing stored random voltages with wide time correlations possible. Externally applied control voltages may be randomized to any desired extent.

Two bandpass filters are on board, each supporting voltage control of pitch, bandwidth, and modulation index. The filters’ inputs are normalled to the flat noise source, allowing for easy creation of filtered noise sounds.

All settings of the 267e can be stored and recalled as part of a system preset using the 225e or 206e Preset Manager.
