The Erica Synths Black Low Pass VCF module is an essential addition to any sound designer's Eurorack setup who wants to take music-making to the next level. It is a highly stable 24dB/oct resonant low pass Voltage Controlled Filter (VCF) that offers voltage control over both cutoff and resonance for complete sound manipulation.
The module comes with additional features such as a post-filter overdrive circuit, which allows users to adjust the drive amount as needed for a more dynamic sound. The module also includes a Black Filter Coupler connector, which is a bonus feature that enables the combination of the Black High Pass VCF and the Black Filter Coupler to create the ultimate VCF for an analogue modular system.
One unique feature of the Black Low Pass VCF is the gain loss compensation on high resonance. This allows users to maintain a consistent volume level at high resonance settings, preventing any drastic changes in volume that may occur with other filters.
The cutoff CV attenuverter is another excellent feature that allows for even more control over the sound output. It enables the user to control the amount of attenuation or amplification of the cutoff frequency signal.
The Erica Synths Black Low Pass VCF is designed for analogue purists who take sound design seriously. It offers unparalleled quality and sound shaping options that are not found in other VCF modules on the market. When paired with the Black High Pass VCF and the Black Filter Coupler, it creates the Holy Trinity of VCFs for the ultimate analogue modular system.
In summary, the Erica Synths Black Low Pass VCF is a top-quality module that offers a range of features, making it perfect for sound designers who want to take their music-making to the next level. With voltage control over cutoff and resonance, an adjustable post-filter overdrive circuit, and a Black Filter Coupler connector, this module provides exceptional sound manipulation possibilities.
Example Usage
If you're new to modular synthesis and want to experiment with the Erica Synths Black Low Pass VCF, start by patching a basic sound source such as an oscillator into the module's audio input and send the output to your amplifier or mixer. Then, turn the cutoff knob to decrease the amount of high frequencies in the sound and hear how it affects the tone. Try using the cutoff CV attenuverter to modulate the cutoff with an LFO or envelope generator for more dynamic results. Finally, experiment with the post-filter overdrive circuit to add distortion and grit to your sound. With a little practice, you'll be amazed at how this filter can help shape your sound.
An intermediate-level example of using the Erica Synths Black Low Pass VCF module is creating a classic acid bassline. Start by sending a square wave from your oscillator to the VCF's input. Use the voltage control over the cutoff to find the sweet spot for your bassline. Then, increase the resonance to give it some bite. Use the overdrive circuit to add some grit and distortion to the sound. Finally, modulate the cutoff frequency with an envelope or LFO for some movement and add some accent notes to create a dynamic and energetic bassline reminiscent of classic acid tracks. The Erica Synths Black Low Pass VCF module's versatile features allow you to create a wide range of sounds and add a unique character to your productions.
Further Thoughts
For a unique and dynamic sound, try using the Erica Synths Black Low Pass VCF in conjunction with the Black High Pass VCF and the Black Filter Coupler. By utilizing all three modules, you can achieve a wide range of filtering options while maintaining a stable and resonant low pass sound. Additionally, the post-filter overdrive circuit allows for further customization by adjusting the drive amount to add distortion and character to your sound. This powerful combination creates an ultimate analogue modular system that takes sound design to another level.
