Erica Pico VCF1


Come explore the beauty of Erica Pico VCF1 and experience the power of superior sound quality.



Erica Synths has released a new addition to their Pico series, the Pico VCF1, a compact yet powerful analog filter module for Eurorack systems.

With a narrowed width of just 3HP, the Pico VCF1 packs quite a punch. It features a voltage-controlled low-pass filter with a slope of -12dB, -24dB or -48dB per octave. Its resonance circuit is capable of boosting frequencies in a specific area, giving the sound presence and character. For added versatility, the filter can also morph between low-pass, band-pass and high-pass modes.

The Pico VCF1 is ideal for shaping the tone of synth sounds and adding texture to drum hits, loops, and samples. Its compact form factor makes it perfect for smaller setups or for those looking to maximize their Eurorack space.

The module is easy to operate, with just three knobs controlling cutoff frequency, resonance, and filter mode. Additionally, the module can be driven by an external signal via the CV input, allowing for more complex and dynamic filtering.

The Pico VCF1 can also be chained with other Pico modules to create a powerful, portable synth setup. As with all Erica Synths products, the build quality is sturdy and reliable, ensuring years of use.

In conclusion, the Erica Synths Pico VCF1 is a versatile and compact filter module that provides high-quality sound shaping in a small package. Its simplicity of use makes it suitable for beginners, while its powerful features will appeal to more advanced users. Overall, the Pico VCF1 is an excellent addition to any Eurorack setup.

Frequently Asked Questions:

How does the Erica Synths Pico VCF1's self-oscillating mode differ from traditional low-pass filtering techniques, and what unique tonal characteristics does it offer?

The Erica Synths Pico VCF1's self-oscillating mode differs from traditional low-pass filtering techniques in that it allows the filter to oscillate at a frequency of its own accord. In contrast, traditional low-pass filters are designed to attenuate high-frequency signals and allow lower frequencies to pass through, creating a smooth, gradual roll-off response. The self-oscillating mode of the Pico VCF1 offers several unique tonal characteristics. Firstly, it allows for the creation of complex, harmonically rich tones that are not achievable through traditional filtering techniques. These tones can be highly resonant and have a distinct timbre that is often described as metallic or bell-like. Secondly, due to the self-oscillating nature of this mode, it can act as a versatile oscillator in its own right, providing additional tonal options beyond those available through traditional VCOs. This makes it highly useful for creating complex, interlocking textures and sequences. Finally, the Pico VCF1's self-oscillating mode offers a high degree of modulation possibilities, as the oscillation frequency can be controlled by external signals or other modules within a modular system. This allows for a wide range of tonal variations and sonic experimentation. Overall, the Erica Synths Pico VCF1's self-oscillating mode offers a unique and highly versatile tool for creating complex, harmonically rich tones, interlocking sequences, and modulation possibilities that are not achievable through traditional filtering techniques.

How can I optimize the filter response of the Erica Pico VCF1 to achieve maximum sonic versatility in my synthesized sounds?

To optimize the filter response of the Erica Pico VCF1 and achieve maximum sonic versatility in your synthesized sounds, you should follow these steps:

1. Explore the filter cutoff frequency: The cutoff frequency determines at which frequencies the filter begins to attenuate the signal. By sweeping this parameter, you can hear how different frequencies are affected by the filter. Start with a low cutoff frequency and gradually increase it until you reach the desired level of resonance. Adjust the filter resonance: Resonance is the amount of boost or peak at the cutoff frequency. High resonance values produce a more pronounced peak, while lower resonance values result in a smoother response. Experiment with different resonance settings to find the sound you're looking for. Use filter envelope: The Erica Pico VCF1 has an ADSR envelope that can modulate the cutoff frequency and resonance parameters. This allows you to create dynamic filter responses that can change over time. Try using the envelope to make your sounds more expressive. Experiment with filter slope: The filter slope determines how steeply the signal is attenuated as it approaches the cutoff frequency. Higher slopes result in a sharper roll-off, while lower slopes produce a gentler roll-off. Try using different slope settings to shape your sounds. Use filter tracking: Filter tracking allows you to synchronize the filter response with an external audio source or oscillator. This can be useful for creating complex modulation effects and phasing phenomena. Try using filter tracking to add depth and complexity to your synthesized sounds. By following these steps, you should be able to optimize the filter response of the Erica Pico VCF1 and achieve maximum sonic versatility in your synthesized sounds.
