Undeniably captivating in its capabilities, the Serge VC Resonant Equalizer stands as a monumental tool in any Eurorack setup. Perhaps what sets it apart from other modules in its category is its design inspiration: acoustic instrument resonances. It marries classic, time-honored sound quality with the flexibility of electronic control, resulting in a unique sonic palette that breathes new life into sounds, whether for processing or creation.
Dive into its features, and the first thing to catch your eye (and ear) would be the ten filter bands. But these aren’t just any filters; each one is capable of emulating the resonant peaks and valleys that you'd usually find in acoustic instruments. From the lush harmonics of a violin to the nuanced overtones of a piano, the VC Resonant Equalizer offers a plethora of sonic possibilities that lend depth and character to your sounds.
But what makes each filter truly versatile is the inclusion of voltage control. Coupled with an attenuverter, this allows for precise determination of how incoming CV will affect each band. You are provided with the freedom to emphasize or shift the focus of each band, ushering in a degree of control that goes beyond just mere equalization. Combine that with the individual band outputs, and you start to appreciate the amount of flexibility the Serge VC Resonant Equalizer is capable of.
Yet it doesn't stop there. Beyond its workhorse role as a filterbank, the Resonant Equalizer can also be pushed into uncharted territory. The CV inputs can be used to feed audio signals - whether from an external oscillator or drawn from the module itself - morphing the Resonant Equalizer from a mere processor to potentially a sound source.
Moreover, an added two-channel mixer with attenuators and a transformative feedback section only serve to expand the module's arsenal. This feedback function allows users to feed the output signal back into itself, opening the door to a world of rich, complex, and sometimes unpredictable textural designs.
The module also features three equalized outputs, specifically, the dual Comb outputs and the collective mix from all filters. The Comb outputs lend complexity to the audio signal by summing alternate filter bands, painting a sonic image that is layered and intricate. And though the module stresses that there are no sharply defined separations between the bands, any movement of the frequency knobs will reflect on the Comb outputs, offering more creative control over the sound.
Overall, the Serge VC Resonant Equalizer is not merely a tool in your Eurorack system, but a critical ingredient in the process of sound design. Its blend of familiar acoustic emulation with cutting-edge voltage control inspires both beginners and seasoned music-makers to explore the sonic depths with a renewed sense of curiosity and creativity. No other module so seamlessly unites traditional sound processing with imaginative sound creation, making it a must-have for any serious electronic musician. Its role in the Eurorack scene cannot be overstated, and the scope of its capabilities is just waiting to be discovered.
Example Usage
The Serge VC Resonant Equalizer opens a world of sonic possibilities, perfect for novice users eager to start experimenting with sound processing. To get started, set up the module in your Eurorack case and connect it to a sound source, such as a simple oscillator or a drum machine, using the audio input.
Begin by tweaking the frequency knobs for each band. You will quickly notice how altering these controls shapes the tonal character of your sound, creating peaks and valleys reminiscent of natural acoustics. For a starting point, focus on the lower frequency bands to create a deep, resonant foundation. Then, gradually increase the frequency of the higher bands to introduce a brighter, more dynamic texture.
Next, explore the voltage control (CV) capabilities. Patch a simple control voltage source, like an LFO or an envelope generator, into one of the CV inputs. Adjust the attenuverter for that band to find the right balance—whether you want to boost or cut frequencies—ultimately transforming your sound over time. You can even experiment with patching audio from one of the individual outputs back into the CV input to create unique feedback loops, resulting in rich harmonic textures.
As you experiment, make use of the two Comb outputs. These outputs blend alternating filter bands, which can create a fuller sound. Play with the levels on the built-in two-channel mixer to balance the various outputs, allowing you to sculpt your final sound even further.
Finally, don't shy away from the Feedback section. By routing the output back into the input, you can achieve extreme resonance and create self-oscillating effects that generate an entirely new layer of sound. Remember, the key is to explore and play; every tweak can lead to unexpected discoveries in the lush sonic landscape of the Serge VC Resonant Equalizer.
The Serge VC Resonant Equalizer is a powerhouse for sound shaping and processing that allows for deep exploration of frequency manipulation. To illustrate its capabilities, consider an example that integrates this module into a Eurorack system focused on creating dynamic soundscapes.
Begin by routing a rich, textured sound source, such as a wavetable oscillator, into the input of the Resonant Equalizer. This source will serve as the foundation for your processing. Set the EQ’s frequency bands to highlight the upper and lower ranges; for instance, emphasize the mid to high frequencies while gently attenuating the lows. By perfectly balancing these adjustments, you open up space for your sound to breathe while still retaining its character.
Next, utilize the voltage control inputs to dynamically shape the frequencies. Connect a random voltage source, like a sample-and-hold module, to one of the CV inputs on the Resonant Equalizer. This will allow the frequency bands to shift unpredictably over time, injecting a sense of liveliness into the sound. As the voltage varies, observe how different resonant peaks emerge and subside, creating a rich tapestry of tonal color.
To further explore this module’s potential, make use of the feedback section. Take one of the outputs, such as the summed outputs from the filters, and route it back into the feedback input. Adjust the feedback level gently to introduce subtle harmonics and added complexity. The interaction of the feedback with the resonant peaks can lead to self-oscillation; however, finding the sweet spot will be key to avoiding overly harsh sounds.
Experiment with external audio signals as well. Feed the audio output from another module, such as a drum machine or sampler, into one of the EQ’s inputs. This approach can significantly enhance your drum sounds, giving them an organic quality reminiscent of live instruments. By sweeping the frequency bands while adjusting the feedback, you can sculpt a driven, saturated texture perfect for electronic music that demands attention.
Finally, mix the outputs using the two-channel mixer, adjusting the level of each to balance your processed sound within the overall mix. Pay particular attention to the two Comb outputs; the interplay between them will allow you to create complex sound textures that evolve with each movement of the controls.
By creatively exploring these routing options and utilizing the Serge VC Resonant Equalizer’s features, you'll tap into a world of sonic possibilities, providing depth and richness to your music that is hard to achieve with conventional effects processing.
Further Thoughts
When integrating the Serge VC Resonant Equalizer into your Eurorack system, consider its capabilities not merely for EQ adjustments but as a multifaceted tool for sound shaping and creative expression. Start by feeding a rich, complex sound source into the module, such as a drum loop or a dense melodic line. This will allow the unique characteristics of the Resonant EQ to shine through as you sculpt the sound.
Begin with the basics by engaging the ten individual filter bands. Experiment with the CV inputs, applying modulation from a LFO or an envelope generator to manipulate the resonant peaks dynamically. This can create an evolving sound that mimics the natural movement of acoustic instruments. For instance, set a slow LFO to modulate the cutoff frequencies of several bands simultaneously, and watch how the changes in resonance alter the tonality and texture of your source material.
Next, engage the attenuverters for each band. This is where the real magic happens. By adjusting these controls, you can emphasize specific frequency ranges that resonate well with the input signal while attenuating others to create interesting dips and valleys. For example, if you're processing a vocal sample, try boosting the frequencies around 2-3 kHz to enhance the clarity and intelligibility while pulling back on the lower frequencies to avoid muddiness.
The module’s feedback section can be a game changer as well. Run the output back into the input, which can generate complex textures and resonant cavities that evolve with time. Use a short delay to create a self-oscillating effect for dramatic sonic builds. It’s particularly effective during a live performance to add dynamic tension to your sets.
Utilize the two Comb outputs to experiment with layered mixing. By bringing together the two alternate filter bands, you can create distinctive tonal movements. Consider panning these outputs in your mixer for spatial depth, creating a stereo image that evolves against your backdrop of sounds.
Finally, leverage the individual outputs for multi-channel processing in your larger Eurorack system. By routing specific filter bands to different effects or channels in your mixer, you can create intricate layering of sounds that adds richness and depth to your compositions.
Integrating the Serge VC Resonant Equalizer into your workflow is not just about equalization—it's about embracing a rich palette of sonic manipulation, allowing you to explore uncharted territories in sound design and performance.
