This module produces a great variety of audio rate noise sources, from delicate glitch textures to brutal walls of harsh noise, with two separate but related channels. It uses two square wave oscillators modulating each other and going through clock dividers, resulting in chaotic relationships that can produce many interesting sweet spots in its parameter space.

Each oscillator has frequency and pulse width controls, along with controllers for the respective clock dividers. All these parameters are CV controllable, through the respective inputs at the bottom (these are unlabeled but correspond to the order of the knobs above). There are also fine controller for frequency, which can be useful for making small adjustments when trying to find sweet spots that produce interesting behavior. There are also two 3-state switches that set the system into different modes, reconfiguring the signal processing path. This makes the module very powerful, giving you a vast parameter space to explore. The switches can also be CV controlled, accepting signals between -5 and 5 V to set the position of the switches.

Be aware that some setting can produce asymmetrical signals, with a certain amount of DC offset. Experiment with processing the signals through filters and compressors for an ever wider pallet of sounds. This module is perfect for noise music, or to add some glitch elements to your mix. It's also great for driving your parents or neighbors crazy, if you should ever desire to do so!

Included in the Benard Mega Bundle Vol. 2.

Documentation

-Rate - These knobs set the frequency of the two square wave oscillators.

-Fine - Fine tune the frequency values.

The final frequency will be the result of the Rate knob value plus the Fine knob value, but this is reflected automatically on the displayed tooltips for both knobs.

-Divisor - These knobs set the value of the clock divider used in the signal path.

-PW - These knobs set the pulse width of the square waves.

-Mode - These 3-position switches allow you to reconfigure the signal path in different ways, to achieve different sounds. They can be CV controlled with the inputs next to them, which accept values between -5 and 5 volts. A signal value below -1.666 will set them to 0, between -1.667 and 1.666 will set them to 1, and anything above 1.666 will set them to 2.

-CV Inputs - There are 3 CV inputs per channel, which correspond to the knobs at the top. Each one has an attenuverter, and the values are added to the value of the respective knobs. They all accept values between -5 and 5 V.

-Outs - These are the sound outputs of the oscillators after going through the dividers. Depending on the mode, the signals can be close to each other, or be completely different, but because of the intermodulation of the oscillators the signals are always related in some way, and changes to the parameters of one oscillator often have an effect on both output signals. The small knobs next to the out jacks control the level of the output signals.
