In the realm of electronic sound design, one module has emerged as a trailblazer in sculpting soundscapes that echo the resonances found in acoustic instruments. The Random*Source Resonant Equalizer - Dr. Wiener Edition, or RESONANT EQUALIZER (EQ) as it's also known, is a distinctive ten-band filter that allows users a broad spectrum of possibilities to mold their unique sounds.
Unlike traditional equalizers that manipulate directly adjacent frequency bands, the RESONANT EQUALIZER (EQ) has spaced its bands at an interval of a major seventh. This innovative design brings forth a revelation in sound synthesis by simulating formant peaks and valleys akin to those in acoustic instruments. Not restricting itself solely to the tonal properties of string or wind, it encourages an exploration into the universe of resonant effects completely unique to synthesized landscapes.
This module offers three equalized outputs: the two COMB outputs and a summation of all bands. It is pertinent to remember that there is no rigid separation between the bands. Any modification to the frequencies will influence both COMB outputs, encouraging an interactive, intuitive, and exciting hands-on approach to sound design. Sculpting your sound is not only about precision but an organic tinkering that the RESONANT EQUALIZER (EQ) brings to your fingertips.
What sets this module apart is its resonance control. Bands can become resonant when the knobs are set beyond the 3 o’clock position, simulating the natural resonance found in acoustic instrument formant structures. And, in counterpoint, setting the knob below the 9 o’clock position results in amplified band rejection.
The Random*Source remix of the original takes things a notch higher by including an auxiliary input mixer with two entries and a feedback section. Users can modify the input signal's amplitude before it's sent into the EQ, opening up the gates to creative distortion possibilities. The feedback section, too, is a notable addition. It feeds the output signal back into itself, culminating in fascinating phase cancellation effects.
And no discussion of the Random*Source Resonant Equalizer - Dr. Wiener Edition would be complete without highlighting its DIY nature. Licensed by Serge, the legendary equalizer is now available as a Eurorack-compatible DIY kit. This offers a deeply satisfying journey into understanding the building blocks of sound and the craft of manipulating it, making it an indispensable tool for any serious synthesist or sound engineer.
In essence, the RESONANT EQUALIZER (EQ) pushes the boundaries in electronic sound design. Its one-of-a-kind, DIY multi-band filter coupled with a surge of creative options and the legendary Serge pedigree makes it a must-have for anyone serious about their craft. Whether molding soundscapes that echo natural resonances of our physical world or pushing into the uncharted territories of synthesized resonance, the Random*Source Resonant Equalizer - Dr. Wiener Edition stands as a beacon of innovation in the Eruorack universe.
Example Usage
To start using the Random*Source Resonant Equalizer - Dr. Wiener Edition, begin by patching an audio source to one of the two input jacks. The module's input mixer allows you to adjust levels before the signal enters the equalization section, making it ideal for blending multiple sound sources or applying pre-EQ effects.
After connecting your audio source, explore the function of the ten-band equalizer. The layout features frequency bands spaced at intervals of a major seventh, which influences the character of the sound you will shape. As you rotate each band’s knob, observe how the levels adjust in a gentle, musical manner rather than a stark cut-off. The middle position of each band provides a flat response, so you can achieve subtle adjustments by increasing or decreasing levels between the 9 and 3 o’clock positions.
To create resonant peaks, move the knobs past 3 o’clock. This will generate pronounced formant-like characteristics within your sound, emulating the resonance found in acoustic instruments. Experiment with these settings while listening closely to how the harmonics shift. If you’re working with rhythmic elements, try using the feedback section. By sending the output back into the EQ via the feedback knob and manipulating the phase switch, you can create complex textures and tonal variations. Inverted feedback can produce fascinating phase cancellation effects, providing yet another layer of sonic depth.
For a hands-on experience, try combining an arpeggiated synth line with a percussive element. Use the EQ to sculpt the synth's tonality while allowing the percussive sound to poke through. This clever manipulation of resonance and feedback can lead to unique soundscapes that breathe life into your compositions.
The Random*Source Resonant Equalizer - Dr. Wiener Edition demonstrates its capabilities effectively through a variety of sound design scenarios. An intermediate user can begin by utilizing the equalizer to enhance a simple sine wave generated by a VCO. Start with a basic oscillator patch; route the sine wave signal into the Resonant Equalizer's input mixer and adjust the levels to achieve a balance that suits your sound.
Next, experiment with each of the ten frequency bands by gradually turning the knobs to find areas of resonance that complement your sine wave. As you position the knobs around the 9 o'clock area, you will notice a boost or cut, which can dramatically alter the tonal quality. Push the knobs towards the 3 o'clock position to introduce resonance to particular bands; this is particularly effective when targeting formants. The natural resonances you create can mimic the tonal characteristics of traditional acoustic instruments, enriching your electronic sound.
Using the two COMB outputs, you can blend the alternate frequencies and create complex sound layers. Try EQing one output differently from the other to create interesting contrasts or harmonics. This method is especially rewarding when you set one output to emphasize lower frequencies while the other focuses on the highs.
Incorporate the Feedback section by routing one of the outputs back into the input mixer. Begin with the knob set to about halfway and listen to how the feedback adds subtle distortion to your sound. Experiment with both the feedback and phase settings: the inverted feedback will introduce unique phase cancellation effects, perfect for achieving a more ethereal texture.
To enhance this newly shaped signal, patch it into another module, like a delay or reverb, and observe how the processed feedback interacts with the modified EQ output. This layered approach allows you to deeply explore sonic textures and create lush, evolving sounds.
Throughout the process, pay close attention to how the adjustments to the filters affect the overall mix. The interconnected nature of the bands means that minor changes can have a significant impact, encouraging a more exploratory and iterative approach to sound design. By embracing these techniques, you will unlock the true potential of the Random*Source Resonant Equalizer and delve deeper into your electronic sound synthesis.
Further Thoughts
The Random*Source Resonant Equalizer (RESEQ) Dr. Wiener Edition stands out as an exceptional tool for sound designers and electronic musicians seeking to manipulate frequency bands with precision and creativity. In this expert-level usage example, we’ll explore its capabilities through a practical application, showcasing how to sculpt complex audio textures using this ten-band filter.
To begin, patch an audio source, such as a drone oscillator or a percussive loop, into the input of the RESEQ. Utilize the two available inputs on the input mixer to blend different sound sources, allowing for a thicker texture or more complex coloration. Experiment with the levels to create a desired harmonic blend before the signal reaches the equalizer. This initial mixing stage is crucial, as it lays down the foundation for further manipulation within the RESEQ.
Next, tweak the frequency bands to highlight specific characteristics of your sound. The unique spacing of the bands – particularly the major seventh interval – allows for the generation of formant-like peaks, reminiscent of organic instrumental timbres. Start by setting all frequency knobs to the flat position (around the middle). Then, gradually adjust individual bands between the 9 and 3 o’clock positions, noticing how each adjustment impacts the spectral content. If aimed at achieving a robust resonant effect, push the knobs beyond the 3 o’clock threshold, creating pronounced resonances that energize the sound.
Utilizing the feedback section is where the RESEQ truly shines. Activate the feedback loop, first experimenting with the normal feedback setting. This will tend to enhance the resonant qualities of the adjusted frequency bands, resulting in a rich, textured output. Take note of how the sharpness of the peaks changes in response to subtle adjustments of the frequency knobs. For more adventurous outcomes, switch to the inverted feedback mode. This approach engenders phase cancellation effects, leading to interesting sound thinning and dynamic shifts in the audio signal. Play around with the phase switch while adjusting the feedback level to uncover unexpected sonic behaviors.
As you delve deeper into the sonic palette offered by the RESEQ, consider using modulation sources to dynamically alter band frequencies over time. For instance, connect an LFO or an envelope generator to control the frequency knobs. This allows the filter to respond to changing dynamics, creating evolving soundscapes or rhythmic textures as the RESEQ continually reshapes the audio material.
Finally, interface the outputs of the RESEQ with other modules in your Eurorack system. The COMB outputs can be particularly useful for processing in parallel with other effects or sequences, further expanding your sound design possibilities. Experimenting with different combinations and signal paths will unveil the potential to craft unique auditory experiences, characterized by the lush resonances and formant structures intrinsic to the design of the Random*Source Resonant Equalizer.
