Exploring the Sonic Landscapes: Unleashing the Potential of the Nonlinearcircuits Fourier Black Eurorack Module

Entwining the sci-fi-esque principles of Fourier Synthesis and a hint of Walsh, the "nonlinearcircuits-fourier-black" module presents itself as an enticing tool for electronic music aficionados seeking to finally step into the unexplored sonic territories. Presented initially by E. Muller in the “Ejektor” section of 'Jan 1983 Elektor', this module is far from perfect but exudes an enchanting potential.

Where the real beauty of this module lies is in its offering of shifting soundscapes and drones. Those yearning to tap into the world of ever-evolving soundscapes, the module is your ticket to that utopia. Imagine having control of 7 sine and 8 cosine signals, presumed to be harmonics of initial signals, at your fingertips. But these waves are not your conventional sinewaves; they are rather stepped pulse waves, serving to elevate the unpredictable aspect of your creation.

Most would suggest patching this module into a low pass filter or any VCF for that matter for standard use. But isn't music all about breaking norms and experimenting? Therefore, we encourage you to override such recommendations occasionally and explore the uncharted. Be it a fast clock signal from a VCF or a slow clock signal. The multiplexer scans through the channels and feeds the signal to the output at a rate 16x faster than what you want to hear when fed by a fast clock signal. This multiplexing process essentially forms the core of the module's operation.

Additionally, the module also accommodates a secondary MUX, which can operate independently or at half the rate of channel 1's clock signal. The outputs of both channels are available individually and mixed, offering a pot to set the level of channel 2, hence, doubling as a sub-harmonic source.

The uniqueness of this module extends further with it being transformed into an atypical sequencer or pattern generator when fed with a slow clock signal. Moreover, each channel is equipped with its own reset and direction inputs, allowing you to indulge in a sonic play as per your whims.

Additionally, each pot or input is wired to multiple channels, which are then responsible for creating harmonics for each stage. With external signals replacing the pots, there is an instantaneous cut from the circuit, denoting exclusivity of operation.

The module is truly unleashed when CVs are patched into the harmonic inputs. Specifically, slow ones from Sloths or LFOs generate an intriguingly layered soundscape. Feeding audio signals can create stunning effects. Using white noise not only adds another layer of interest but using it as a clock source opens up a completely different realm of sonic exploration.

In conclusion, the "nonlinearcircuits-fourier-black" module is a sonic sorcerer's stone that seamlessly transforms base sounds into mesmerizing sonic tales. It is not just a tool; it's a metamorphosing playground for the creative, an abstract canvas for the daring, and an auditorium for those seeking the thrill of unpredictability.

Let's dive into the magical world of the Nonlinearcircuits Fourier Black Eurorack Module. This module opens up a realm of shifting soundscapes and drones, allowing you to unleash your creativity and explore sonic possibilities like never before.

To start, patch the Fourier Black module into a low pass filter (VCF) for normal use. However, don't be afraid to experiment and try different combinations if you're feeling adventurous. Since most cases already have a VCF installed, you're good to go.

The module thrives on a fast clock signal from a VCO. It's crucial that the clock signal is 16 times faster than your desired sound. This clock signal is then fed into a multiplexer (MUX), which scans through the channels and delivers the sound to the output. There are two MUX options that can be operated independently, with channel 2 receiving a clock signal at half the rate of channel 1.

You have the flexibility to use each channel's output individually or mix them together. If you choose to mix them, there's a dedicated pot to adjust the level of channel 2, allowing it to act as a sub-harmonic source. Additionally, you can introduce an external signal to be mixed instead of channel 2, expanding your sonic palette even further.

The module can also be used as a rather unique sequencer or pattern generator by feeding it a slow clock signal. This feature opens up exciting possibilities for creating intricate, evolving rhythms and sequences.

Feel free to experiment with the reset and direction inputs on each channel, as they offer you the opportunity to manipulate the proceedings according to your creative vision.

One aspect that adds depth and complexity to your sound exploration is patching CVs into the harmonic inputs. Slow CV signals from sources like the Sloths or LFOs work wonderfully, providing subtle and evolving changes to the harmonics. You'll be amazed at the variety of textures and timbres you can achieve.

Of course, audio signals are perfect for the Nonlinearcircuits Fourier Black module. Don't hesitate to experiment with different sound sources, such as white noise, to create captivating and unique sonic textures. And if you're feeling particularly adventurous, use white noise as a clock source - the results will astound you.

Ideally, the clock signal should be around 16 times faster than the desired audible result. Experiment with different clock rates to explore a range of sonic possibilities.

Step 3: Outputs The module has two independently operable multiplexers (MUX). The first MUX controls channel 1, while the second MUX has a clock signal at half the rate of channel 1. Channel 1 and channel 2 outputs can be used individually or mixed together using the provided level potentiometer. Adjust this potentiometer to control the level of the mixed output or replace channel 2 with an external signal for further variation.

Step 4: Reset and Direction Each channel in the Fourier Black module has its own reset and direction inputs. Experiment with patching CV signals into these inputs to introduce modulation and alter the harmonic progression.

Step 5: Harmonic Inputs The pots (or inputs) on the module are responsible for creating the harmonics for each stage. To explore more sonic possibilities, try patching control voltage signals from sources like slow LFOs or Sloths into these harmonic inputs. This will dynamically shape the texture and movement of the generated sounds.

Step 6: Creative Experimentation Feel free to introduce audio signals into the harmonic inputs as well. Try using white noise and explore its interaction with the Fourier synthesis. For intriguing results, you can even use white noise as a clock source, creating unique and unexpected sonic patterns.

By following these steps and embracing creative experimentation, the Nonlinearcircuits Fourier Black module can serve as a powerful tool for designing evolving soundscapes, drones, and experimental sequences within your Eurorack system.

In this example, we will explore the sonic possibilities of the Nonlinearcircuits Fourier Black Eurorack module by creating a shifting drone-like sound using CV modulation.

First, ensure that the module is patched into a low pass filter for normal use. The output of the module will be influenced by the characteristics of the filter, so feel free to experiment with different types to achieve your desired sound.

To begin, connect a fast clock signal from a VCO to the module's clock input. The clock signal should be approximately 16 times faster than the desired pitch of the output. This clock signal will be used to scan through the channels and generate harmonic signals.

Next, set the potentiometers or input levels for each channel to create the desired harmonic content. You can start by adjusting the sine and cosine signals for each channel, keeping in mind that the module generates stepped pulse waves rather than pure sine waves. Consider using CV modulation sources, such as slow LFOs or Sloths, to modulate the harmonic inputs for each channel. This can add subtle variation and movement to the sound.

Now, listen to the output of the module and explore the rich harmonic timbres created by the Fourier synthesis. You can adjust the levels of channel 2 using the dedicated potentiometer to introduce sub-harmonics or mix in an external signal instead. This allows for even more sonic possibilities and can result in complex and evolving textures.

For an experimental twist, try using white noise as both an audio signal and a clock source. The unpredictable nature of white noise can lead to fascinating and unique sonic landscapes. Don't be afraid to push the boundaries and explore unconventional sound design techniques.

Additionally, you can utilize the reset and direction inputs for each channel to further manipulate the sound. Experiment with different combinations and timings to create rhythmic patterns or chaotic sonic movements.
