Example Usage

Novice-level usage example:

Now let's take a look at how you can use the Noise Engineering Roucha Legio Stereo Resonant Multimode Filter in a simple setup. Imagine you have a basic eurorack system with a sequencer, an oscillator, and the Roucha Legio filter.

First, connect the output of your oscillator to the input of the Roucha Legio filter. This will send your audio signal through the filter. You can experiment with different waveforms and frequencies to hear how they are affected by the filter settings.

Next, connect the output of the Roucha Legio filter to your speakers or mixer. Now you should be able to hear the filtered sound.

Start by turning the filter on and selecting a filter type. You have three options: lowpass, bandpass, and highpass. Try them out and see which one suits your sound the best.

Now, use the dedicated frequency encoder to control the cutoff frequency of the filter. Turning it clockwise will increase the cutoff frequency, allowing more high-frequency content to pass through. Turning it counterclockwise will do the opposite.

To add some resonance and make the sound more interesting, use the CV input for controlling the resonance parameter. You can use a keyboard or sequencer to send control voltage to the CV input. Experiment with different levels and see how it affects the filter's resonance.

If you want to add some extra character to your sound, try adjusting the Fold knob. This adds wavefolding to the signal chain, creating harmonically rich and complex tones. You can place it before the filter, after the filter, or both, depending on your desired effect.

To create dynamic filter sweeps and automate the Roucha Legio filter, you can use a gate signal. Connect a gate signal from your sequencer to the Bypass input of the filter. When the gate is high, the filter will remain bypassed, and when the gate is low, the filter will be active. This allows you to easily create rhythmic filter openings and closings.

Remember, the Roucha Legio is not only a filter but also a DSP and oscillator platform. This means that you can change the firmware of the module to other firmware in the Legio series for different functionalities. Make sure to check the Noise Engineering website for firmware updates and new possibilities for your Roucha Legio.

With these simple steps, you can start exploring the sonic depths of the Noise Engineering Roucha Legio Stereo Resonant Multimode Filter and add a whole new dimension to your eurorack system. Enjoy experimenting and creating unique soundscapes with this versatile module!

An intermediate-level usage example for the Noise Engineering Roucha Legio Stereo Resonant Multimode Filter would be creating a dynamic bassline with filter sweeps.

Start by connecting an LFO (Low-Frequency Oscillator) to the CV input of the Roucha Legio to modulate the filter's cutoff frequency. Adjust the LFO rate to achieve the desired speed of the modulation.

Set the Roucha Legio to lowpass mode and dial in a moderate resonance setting. This will create a smooth and round bass sound with a touch of character.

Next, send a gate signal into the Bypass input of the module. This will allow you to automate the filter's bypass function. When the gate signal is high, the filter will remain bypassed, and when it is low, the filter will be engaged.

Now, program a sequencer or a MIDI controller to send a series of gate signals with varying lengths and timings. As the gate signals trigger, the Roucha Legio will alternate between bypassed and engaged states, creating catchy rhythmic patterns in your bassline.

To further enhance the sound, experiment with the Fold knob to introduce wavefolding before or after the filter. This can add harmonics and create more complex timbres, especially when combined with the filter sweeps.

By combining CV-controlled filter modulation, automated bypass, and wavefolding, you can craft a dynamic bassline that evolves and captures the listener's attention. Be sure to explore different LFO shapes, envelope generators, and gate patterns to unlock new possibilities and add your unique sonic touch.

Further Thoughts

One innovative way to use the Noise Engineering Roucha Legio Stereo Resonant Multimode Filter is by incorporating it into a live performance setup for creating dynamic and evolving soundscapes. By connecting an LFO (Low Frequency Oscillator) to the CV input of the filter's resonance parameter, you can achieve mesmerizing filter sweeps that add movement and excitement to your sound.

To begin, set the Roucha Legio module to its lowpass filter mode, which provides a smooth and resonant sound ideal for building up tension. Adjust the cutoff frequency and resonance to your desired starting point.

Next, patch an LFO module's output into the CV input of the Roucha Legio's resonance parameter. Experiment with different LFO waveforms, such as triangle or random, to modulate the resonance. Start with subtle modulation for a gentle wavering effect, and gradually increase the intensity as your performance progresses.

To further enhance the sonic possibilities, utilize the Roucha Legio's wavefolding feature. Patch an audio source, such as a synthesizer or sampler, into the module's input. Play around with the Fold knob to introduce harmonic complexity and distortion to the sound. Try adjusting the Fold before the filter to add subtle harmonics, or after the filter to create more dramatic and intense tonal modifications.

For added versatility, make use of the Roucha Legio's bypass functionality. Tap the encoder to temporarily bypass the filter, creating moments of clarity and contrast. To automate this bypass effect, engage a gate signal into the Bypass input. The filter will remain bypassed as long as a high gate is present, allowing you to dynamically control the filter's presence in the mix.

The Roucha Legio also stands out due to its flexibility as a DSP and oscillator platform. Take full advantage of this by exploring different firmware options available within the Legio series, providing access to a variety of filter algorithms and sound possibilities.

By incorporating the Noise Engineering Roucha Legio Stereo Resonant Multimode Filter into your live performance setup, you can push the boundaries of sonic exploration, creating captivating textures and immersive atmospheres that engage and captivate your audience.
