The MFE 303 Eurorack module is a versatile filter module that promises to revolutionize the art of music-making. Comprising three Steiner-Parker filter units, light overdrive input amplifiers, a 3-channel equalizer, and an audio summing mixer, this module is designed for live performance, sound design, and experimental music.
The core of each filter section is based on the legendary Steiner-Parker filter, which is known for its hard and precise sound. However, in intensive experimental studies, the team at Tronix Audio was able to modify the difficulties of uncontrolled self-oscillation and the too loudly screaming resonance feedback area to such an extent that they became unique musical filter sections. This has resulted in a sound that is truly extraordinary and unlike any other filter module on the market.
Perhaps one of the most striking features of the MFE 303 module is the fully analog equalizer. Based on a circuit from the early 80s, it consists of three bands - treble, middle, and depth - each with unique characteristics. The treble band has a shelf characteristic, while the middle band has a bell characteristic, and the depth band has another shelf characteristic. In addition to the filter inputs, the EQ has two separate audio inputs, further expanding the module's versatility and functionality.
Each filter channel can be controlled using potentiometers and CV inputs, making it ideal for live performance. Incoming audio material is routed to all filter channels if required, so the MFE 303 is also suitable for stereo filtering.
In conclusion, the MFE 303 Eurorack module from Tronix Audio is a truly unique and innovative filter module that opens up new creative possibilities in sound design and music production. The combination of the Steiner-Parker filter units, equalizer, and summing mixer provides a level of flexibility and control that is unmatched in other filter modules. Whether you're a professional musician or an aspiring sound designer, the MFE 303 is definitely worth considering.
Example Usage
For novice eurorack users, the MFE 303 Triple Multimode Steiner Parker Filter, Mixer, and Equalizer can add a unique and dynamic sound to your patches. Try routing some white noise or a sawtooth wave into the filter section and experiment with the cutoff and resonance controls to create a wide range of interesting sounds. Then, use the equalizer to shape the final output to your desired tone. Don't be afraid to play around with the CV inputs as well to modulate the filter and equalizer sections for even more sonic variety.
An intermediate-level usage for the MFE 303 Eurorack module would be to create a dynamic and evolving filter sweep effect by using all three Steiner-Parker filter units in combination with the mixer and equalizer. Begin by setting each filter unit to a different cutoff frequency and resonance level to create a harmonically rich sound. Then, route a sound source such as a synthesizer or drum machine into the module and adjust the filter cutoff frequencies manually or with CV inputs while using the mixer to blend the output of each filter to taste. Finally, use the equalizer to tweak the overall tonality of the sound and add a touch of drive from the input amplifiers for extra warmth and character. This technique can be used to add movement and excitement to any electronic music production.
Further Thoughts
One of the unique ways to use the MFE 303 Triple Multimode Steiner Parker Filter, Mixer, and Equalizer is to introduce subtle overdrive to the filter inputs using the light overdrive amplifiers. This technique can add warmth and character to your sounds without losing clarity and definition. Additionally, using all three filter channels in tandem with the EQ can create complex and nuanced sonic textures that can be further modulated with CV inputs. Experimenting with stereo filtering is also highly recommended to fully explore the capabilities of this exceptional module.
