The Erica Synths Black High Pass VCF is a versatile and powerful module that is a must-have for any serious sound designer. This module features a highly stable, 24dB/oct resonant high pass VCF with voltage control over cutoff and resonance, which allows you to create precise and dynamic filter sweeps.
The post-filter overdrive circuit with user-adjustable drive amount is a bonus feature that makes this module stand out from other filters on the market. The overdrive effect adds warmth, saturation, and character to your sound, allowing you to create gritty, distorted, and aggressive sounds.
When combined with the Erica Synths Black Low Pass VCF and the Black Filter Coupler, the Black High Pass VCF creates the ultimate analog modular system with a Holy Trinity of VCFs. This combination gives you complete control over your sound, allowing you to filter out unwanted frequencies and create complex and textured sounds.
The Erica Synths Black High Pass VCF also offers gain loss compensation on high resonance, allowing you to maintain a consistent output level even when using extreme resonance settings. Additionally, the cutoff CV attenuverter and voltage control over cutoff and resonance give you even more control and flexibility over your sound.
Overall, the Erica Synths Black High Pass VCF is an essential tool for any sound designer who wants to take their sound to the next level. With its stable and precise filtering capabilities, adjustable overdrive circuit, and voltage control options, this module is sure to inspire your creativity and bring new life to your sound.
Example Usage
If you're new to using the Erica Synths Black High Pass VCF, start by experimenting with the cutoff and resonance knobs. Adjusting the cutoff knob will change the frequency range of the filter, while turning up the resonance knob will emphasize the cutoff frequency and create a peak in the frequency response. Try adjusting both knobs together to sculpt the sound of your input signal.
Once you've got the hang of the basic filter controls, try using voltage control to adjust the cutoff and resonance parameters through your modular synth's CV inputs. This can create complex, evolving filter sweeps and other modulation effects.
For even more creative possibilities, experiment with the built-in overdrive circuit by adjusting the drive amount knob. This can add extra grit and texture to your filtered sounds, and works particularly well with percussive or aggressive input signals. Remember to adjust the gain loss compensation knob to balance the level of the filtered and unfiltered signals.
One way to use the Erica Synths Black High Pass VCF is to create a resonant HPF sweep that is triggered by a sequencer. Set the cutoff frequency to a low frequency and turn up the resonance. Assign the sequencer's CV output to the cutoff frequency input of the module and start varying the voltage at a slow rate. The resonance will emphasize the harmonics in the sweep and produce a unique sound effect. To add some extra spice to the sound, turn up the post-filter overdrive circuit to add some distortion or adjust the drive amount to your liking. This combination of voltage control and overdrive in one module offers endless possibilities for creating new and exciting sounds in your modular system.
Further Thoughts
The Erica Synths Black High Pass VCF is a versatile module that can add both voltage control and overdrive to your modular synth setup. For example, you could use it to add some grit and distortion to a clean oscillator sound by routing the output from an oscillator into the input of the VCF and then using the cutoff and resonance controls to shape the sound. After that, you can engage the built-in post-filter overdrive circuit, adjusting it to taste with the user adjustable drive amount control. Finally, you can use the cutoff CV attenuverter to further modulate the cutoff frequency with an external CV source, making it easy to add some movement and modulation to your sound. Overall, the Erica Synths Black High Pass VCF is an excellent choice for anyone looking to get creative with their modular synth sounds, offering a range of powerful features in a compact and intuitive package.
