Example Usage

Novice-level Usage Example:

Let's start by exploring a simple way to create a bass sound using the Jomox Mod FM Eurorack module. With its eight voices and four operators per voice, we have plenty of flexibility to achieve a deep and punchy bass tone.

Begin by patching a gate signal into the CV/Gate input of one of the voices. This will trigger the sound every time a gate signal is received. Next, let's focus on the operators. Adjust the frequency and overtone modes of each operator to shape the overall character of the sound.

To add some movement to the bass, we can modulate the frequency of one operator with another. Connect a modulation source, such as an LFO, to the frequency modulation input of one of the operators. Experiment with different modulation rates and depths to find the sweet spot for your bass sound.

Now, let's shape the sound using the filters. The Jomox Mod FM module provides both a 4-pole lowpass filter and a 2-pole multimode filter. Start by adjusting the cutoff frequency and resonance of the filters to sculpt the tonal qualities of the bass sound. Don't be afraid to explore different filter types, such as lowpass, bandpass, or highpass, to find the perfect combination for your desired sound.

To give the bass sound a sense of space and depth, we can apply some effects. The Jomox Mod FM module offers a digital reverb and a stereo delay. Dial in the desired amount of reverb and adjust the delay time and feedback to add some spatial effects to the bass sound.

Once you are satisfied with the sound, you can save your settings as a preset for future use. Simply navigate the menu using the intuitive OLED displays and select the option to save the current settings. This way, you can easily recall your favorite bass sounds whenever needed.

Remember, this is just a starting point. With the Jomox Mod FM Eurorack module, you have a vast array of possibilities to explore. Don't be afraid to experiment and push the boundaries of FM synthesis to create unique and evolving bass sounds that will make your music stand out. Happy patching!

Intermediate-level usage example:

In this example, we'll explore how the Jomox Mod FM can be used to create evolving and atmospheric pad sounds. Pads are a staple in electronic music, providing lush and immersive textures that fill up the sonic space. With its powerful FM synthesis capabilities, the Mod FM is a perfect tool for crafting unique and captivating pad sounds.

To start, let's initialize a new patch on the Mod FM. Begin by selecting a blank preset or initializing all parameters to their default values. This will provide a clean slate to work with.

Next, let's dive into the modulation matrix to shape the sound. The matrix allows us to define the relationships between the four operators. For this pad sound, we'll create a cascading modulation structure where each operator modulates the one below it.

Assign Operator 1 to modulate Operator 2, Operator 2 to modulate Operator 3, and Operator 3 to modulate Operator 4. Adjust the modulation depth of each operator to get the desired amount of modulation. Experiment with different modulation depths to find the sweet spot that adds movement and richness to the sound.

Now, let's focus on the frequency ratio and overtone modes of each operator. These parameters greatly influence the harmonic content of the sound. Start by setting Operator 1 to a lower frequency ratio, such as 1:1.5, to establish a solid foundation. Increase the frequency ratio gradually for the subsequent operators to create harmonic complexity.

For the overtone modes, try different settings for each operator. These modes determine the harmonic structure and timbre of the operators. Start with sine waveforms for a clean and pure sound, then experiment with different waveforms like sawtooth or square to add character and brightness.

To further shape the sound, let's engage the analog filter. The Mod FM features a 4-pole lowpass filter with a multimode option. Start by using the lowpass mode and adjust the cutoff frequency to control the brightness of the sound. Bringing the cutoff frequency down will make the pad sound darker and more mellow, while raising it will add more brightness and sparkle.

Consider applying modulation to the filter cutoff using one of the available LFOs. This will introduce subtle movement and variation to the pad sound over time. Experiment with different LFO waveforms and rates to find the right balance of modulation intensity.

Finally, add some effects to enhance the spatial characteristics of the pad sound. The Mod FM offers a digital reverb and stereo delay FX. Apply a generous amount of reverb to create a sense of depth and immersion. Experiment with the delay settings to introduce echoes and reflections that add a sense of space and dimension to the pad sound.

Remember to save your patch once you're satisfied with the result. The Mod FM allows you to store and recall presets, so you can easily revisit your pad sound in future productions.

With the Jomox Mod FM, the possibilities for creating captivating pad sounds are endless. Its flexible modulation matrix, rich harmonic capabilities, and onboard effects open up a world of sonic exploration. Take your time to experiment, tweak, and refine your patches, and you'll unlock the sonic depths of FM synthesis.
