The Meridian Eurorack module, a versatile dual multimode filter array, offers users a wide range of options to shape and blend sounds. With four selectable filter types per side, four selectable filter modes per side, and additional effects including drive and phase shift, the Meridian allows for the creation of unique textures and sonic landscapes.
The name of the module, "Meridian," conveys the idea of convergence and balance, while also emphasizing the separation and refinement of different sonic elements. It represents the meeting point of different sounds, where filters are used to blend, shape, and refine them into a cohesive whole. The Meridian module mirrors this concept by delineating different frequencies and aural elements, generating a defined contrast that shapes the overall sound.
In line with its name, the Meridian offers a choice between two selectable filter types and two selectable filter modes per side, allowing users to reshape and refine the source material into new cohesive textures. Each filter has independently adjustable cutoff, resonance, and contour parameters, giving users precise control over their sound. The PrimeFreq control serves as the center macro control for both filters in tandem.
One of the standout features of the Meridian is the dynamic control called "Ping." This feature is activated through the Ping input, allowing users to create dynamic and animated filter effects. Furthermore, the module can be used in serial or parallel routing configurations and can function as either a stereo system or two independent mono channels.
The Meridian offers a selection of filters, including ladder, OTA, comb, and vocal formant, to generate a vast range of textures. These filters provide different sonic characters and possibilities for sound sculpting. Additionally, the module includes two distinctive effects: a phase shifter with speed, panning, and depth controls, and a drive circuit with level, tone, and crush controls. These effects add further sonic expression and character to the module.
Modulation is a key aspect of the Meridian module, as all its main features can be modulated via CV inputs. With the clock input, users can synchronize the phase shifter to tempo, allowing for clock-synchronized phase shifting effects. This opens up possibilities for rhythmic and tempo-synced modulation, adding movement and groove to your sounds.
Designed with performance and tweak-ability in mind, the Meridian offers users a powerful tool for sound manipulation and exploration. Its intuitive interface and comprehensive range of features make it a versatile and creative addition to any eurorack setup. Whether you're crafting intricate soundscapes or adding subtle textures to your compositions, the Meridian delivers exceptional sound quality and control.
In summary, the Meridian Eurorack module is a dual multimode filter array that embodies the concept of sound convergence. With its diverse filter types, filter modes, effects, and modulation capabilities, it offers users limitless possibilities for sound shaping and exploration. Its name reflects the balance and unity it brings to sound processing while allowing for the separation and refinement of different sonic elements. The Meridian is a powerful and versatile module that opens up new sonic horizons.
Example Usage
Novice-level usage example:
Let's say you're a beginner in the world of eurorack modules, and you're looking for a way to add some unique and creative sound textures to your music. Enter the Modbap Meridian eurorack module, a versatile filter module that allows you to shape and refine your sounds in exciting ways.
To start exploring the Meridian module, let's focus on its dual filters. These filters offer four selectable filter types per side, including Ladder, OTA, Comb, and Vocal Formant. Each filter type has its own unique sonic characteristics, giving you a wide range of possibilities to experiment with.
To get started, let's select the Ladder filter type on one side and the OTA filter type on the other. The Ladder filter type is known for its smooth and creamy sound, while the OTA filter type has a more aggressive and biting character.
Now, let's move on to the filter modes. The Meridian module gives you four selectable filter modes per side: LP, HP, BP, and NOTCH. These modes determine the type of frequency response the filter will have. LP stands for Low Pass, which lets lower frequencies pass through and filters out higher frequencies. HP stands for High Pass, which does the opposite, filtering out lower frequencies and allowing higher frequencies to pass through. BP stands for Band Pass, which allows a specific range of frequencies to pass through while filtering out the rest. Lastly, NOTCH creates a notch or dip in the frequency response, filtering out a narrow band of frequencies.
For example, let's set the left filter to LP mode and the right filter to HP mode. This combination will let the lower frequencies pass through on the left side while filtering out the higher frequencies, and vice versa on the right side.
Now that we have our filter types and modes set, let's try out the effects. The Meridian module offers two effects: a Phase Shifter and a Drive circuit. The Phase Shifter adds a swirling and shifting quality to your sound, while the Drive circuit adds grit and distortion.
For a beginner-friendly experiment, let's apply a subtle Phase Shifter effect to our filtered sound. Adjust the speed, panning, and depth controls to your liking. You'll notice how the sound evolves and moves around in the stereo field, adding depth and movement to your music.
Finally, don't forget that the Meridian module can be modulated via CV inputs, allowing you to shape the sound dynamically. For example, you could use an LFO (Low-Frequency Oscillator) module to modulate the cutoff frequency of the filters, creating rhythmic variations in the sound.
Remember, the Meridian module is all about exploring sound convergence and creating unique sonic landscapes. Don't be afraid to experiment and try different combinations of filter types, modes, and effects. The possibilities are endless, and the Modbap Meridian module is here to inspire your creativity.
One intermediate-level usage example for the Meridian Eurorack module is using it to create evolving filter sweeps in a live performance. By patching a slow LFO into the cutoff CV input of one filter, and a faster LFO into the cutoff CV input of the other filter, you can create a dynamic and evolving movement in your sound. Experiment with different LFO waveforms and frequencies to find the desired effect. Additionally, you can modulate the resonance parameter with an envelope generator to add emphasis and texture to specific parts of your performance. This technique allows you to transform static sounds into expressive and evolving sonic landscapes in real-time.
Further Thoughts
Expert Usage Example:
In this example, we will explore how the Modbap Meridian's diverse filter types and modes, along with its effects, can be used to create evolving soundscapes and complex textures in a live performance setting.
Imagine you are performing a live electronic set, and you want to introduce a gradual transition from a smooth, melodic section to a more atmospheric and gritty sound. The Modbap Meridian can play a crucial role in achieving this sonic transformation.
Start by patching a sequencer output into the cutoff frequency CV input of the Meridian's first filter. Choose the Ladder filter type, set it to low-pass mode, and adjust the cutoff frequency to a moderate setting. This will establish the foundation of your melodic section with warm and familiar tones.
Next, engage the phase shifter effect on the Meridian and configure the panning control to create a stereo widening effect. Modulate the speed of the phase shifter effect with an LFO to introduce subtle movement and depth to the sound.
As the performance progresses, you want to start introducing grittier textures and dissonant elements. Switch to the OTA filter type on the second filter and set it to the notch mode. Increase the resonance to emphasize certain frequencies and create a more aggressive sound. The notch filter mode will allow you to carve out specific frequencies, adding contrast to the overall mix.
To further enhance the edginess of the sound, engage the drive circuit and carefully adjust the level, tone, and crush controls. This will introduce harmonic distortion and add a touch of analog warmth to the sound.
While the performance continues, add modulation sources to the contour parameter of both filters. You can use an envelope generator or an expressive controller to shape the dynamics of the filters and create evolving timbral variations.
To add a touch of unpredictability and organic movement, utilize the Meridian's pingable low-pass gate. Patch an envelope or a random source into the ping input to trigger percussive bursts of filtered sound. Experiment with different ping settings and decay times to find the desired level of rhythmic complexity.
As you reach the climax of your performance, engage the drive effect on both filters simultaneously, pushing the boundaries of the sound even further. The combination of multiple filter types, modes, and effects will create a rich, multidimensional sonic landscape that captures the audience's attention.
In conclusion, the Modbap Meridian's versatility allows you to take your live performances to new heights. By leveraging its various filter types, modes, and effects, along with modulation possibilities, you can create dynamic and evolving soundscapes that captivate your audience. Whether you're exploring melodic territories or delving into gritty textures, the Meridian is your trusty companion in shaping your sonic journey.
