267e is designed to perform three functions: noise generation, randomization of CV signals and band-pass filtering of audio signals.
The noise generator has three outputs:

3 dB / oct - white noise;

-3 dB / oct - white noise with low spectral shift;

Flat - acoustically balanced white noise.

Fluctuating Random Voltages (fluctuation generator of random voltages), allows to achieve a cyclic randomization of the input voltage. The cycle is set by the controller in the range from 0.5 to 50 Hz, and the degree of randomness is set by the "random" controller. A "sample" input is also provided, which allows you to obtain voltage samples (sample&hold effect).

Two bandpass filters are designed to filter noise, however, can be successfully applied to any audio signals. You can adjust the center frequency, bandwidth and the degree of modulation by an external signal. All parameters are controlled via the inputs for CV control signals.

Four functional units are combined into one enclosure to create a musical unpredictability or arrange a “source of uncertainty”. There’s a noise generator at the top of the module. It has three outputs: 3 dB / oct - white noise; -3 dB / oct - white noise...
