Review DOEPFER Dual Multimode Filter Black Eurorack Demo Perfect Circuit

The Doepfer A-121dv Dual Multimode Filter is a versatile and powerful addition to any Eurorack modular synthesizer setup. This filter module offers a rich, analog sound with the flexibility of both voltage-controlled and audio rate filtering.

The heart of the A-121dv is its dual multimode filter sections, each equipped with low-pass, high-pass, band-pass, and notch filtering modes. The filtering can be controlled via voltage input, allowing for dynamic and expressive filtering effects. Additionally, each filter section has an independent resonance control, enabling self-oscillation and generating a wide range of sounds from subtle to extreme.

The A-121dv also includes a number of useful features to expand its functionality. A global bypass switch disables both filter sections, while a global CV attenuverter allows for fine-tuning of the input CV levels. Each filter section has its own dedicated CV input and attenuverter, ensuring precise control over the filtering characteristics.

Another notable feature is the filter frequency switch, which allows for selecting between two different frequency ranges for each filter section. This provides even more versatility, as it allows the user to switch between low and high frequency filtering, depending on the desired application.

The A-121dv is housed in a standard Eurorack format, making it easy to integrate into existing modular systems. It also features robust construction and high-quality components, ensuring reliable performance and excellent sound quality.

In summary, the Doepfer A-121dv Dual Multimode Filter is a must-have module for any Eurorack modular synthesizer setup. Its versatile filtering capabilities, combined with its robust construction and user-friendly features, make it an essential tool for creating expressive and dynamic sounds. Whether you're a seasoned synthesist or just starting out, the A-121dv is sure to inspire and expand your creative possibilities.

The Doepfer A-121dv is a dual multimode filter module in Eurorack format. This filter offers various filtering modes, including low-pass, high-pass, band-pass, notch, and all-pass. Let's discuss its pros and cons to help you make an informed decision.

1. Versatility: The A-121dv's dual multimode capability makes it a versatile filter for both mono and stereo applications.

2. Self-Oscillation: Each filter section can self-oscillate, adding an extra layer of sound design possibilities.

3. Voltage Controlled: Voltage control over cutoff, resonance, and mode adds immense expressiveness to the sound.

4. Skill Level: Suitable for beginners and advanced users due to its simplicity and vast sound design capabilities.

5. Affordability: Compared to other high-end multimode filters, the A-121dv is relatively affordable.

1. Size: The module is not compact, requiring 12 HP of space in your Eurorack system.

2. Complexity: Although versatile, the A-121dv can be an overwhelming choice for beginners due to its numerous features.

3. No CV Attenuverters: The module does not include attenuverters for CV inputs, which might require the use of external attenuators for fine-tuning CV values.

In conclusion, the Doepfer A-121dv is a powerful and versatile filter module with a rich feature set. Its self-oscillating capability, voltage control, and dual multimode functionality make it an excellent addition to any Eurorack system. However, its size and complexity might be drawbacks for some users. If you're looking for a versatile filter and can accommodate its size, the A-121dv is a solid choice. If you're a beginner or prefer a more compact filter, you might want to consider other options. Ultimately, the decision depends on your individual needs and preferences.
