Review DOEPFER X treme Filter Eurorack Demo Perfect Circuit

The Doepfer A-106-1 X-Treme Filter is a versatile and powerful low-pass filter module designed for Eurorack modular synthesizers. This 12 HP module offers an extensive range of filtering capabilities, making it an essential addition to any modular setup.

At its core, the A-106-1 X-Treme Filter is a 24 dB/octave low-pass filter with a resonance control that can generate self-oscillation. However, its true character lies in its many additional features.

One such feature is the selectable filter types. The A-106-1 X-Treme Filter offers 12 different filter types, including the classic 12dB/octave Butterworth, Chebyshev Type I, and Chebyshev Type II filters, as well as more complex and unique options like the Elliptic, Bessel, and Leapfrog filters. Each type provides a distinct tonal character, allowing for a wide range of sonic possibilities.

Another notable feature is the filter's modulation capabilities. The A-106-1 X-Treme Filter includes an envelope follower, a velocity sensor, and a VCA input for external control of the filter cutoff. Additionally, it provides two CV inputs for independent control of the cutoff and resonance, allowing for expressive and dynamic filtering.

Furthermore, the A-106-1 X-Treme Filter includes an ADSR envelope generator, which can be used to shape the filter's response to input signals. This envelope generator can be synced to the Doepfer A-140 VCO, providing a convenient way to create complex and expressive filter sweeps.

The A-106-1 X-Treme Filter also includes a VCA section, allowing it to function as a complete signal processing module. The VCA can be used to control the overall level of the output signal, or it can be bypassed to send the unattenuated filter output to the Eurorack bus.

In terms of connectivity, the A-106-1 X-Treme Filter provides 12 inputs and outputs, including CV inputs for cutoff and resonance, an envelope follower output, a VCA input, and multiple audio inputs and outputs. The module's solid-state design ensures reliable and stable performance, making it a valuable addition to any modular synthesizer setup.

Overall, the Doepfer A-106-1 X-Treme Filter is a comprehensive and versatile low-pass filter module for Eurorack synthesizers. Its extensive range of filter types, modulation capabilities, and additional features make it a powerful tool for shaping and manipulating sound, making it an essential component for any modular synthesist's creative arsenal.

The Doepfer A-106-1 X-Treme Filter is a versatile and powerful filter module in Eurorack format. It offers several features that make it an attractive option for synthesists, but like any piece of equipment, it has its pros and cons.

1. Multimode Filter: The A-106-1 X-Treme Filter provides 12 filter types, including low-pass, high-pass, band-pass, notch, all-pass, and peak. It also includes a self-oscillating high-pass filter and a state variable filter.

2. Resonance: The filter has a high resonance capability, allowing for self-oscillation and creating interesting and unique sounds.

3. Modulation: The module offers multiple sources of modulation, including an ADSR envelope generator, an LFO, a CV input, and an external audio input.

4. Flexible Control: The filter has a range of control options, including a dedicated input for external filter frequency modulation and a voltage controlled frequency knob.

5. Compact Size: The module is relatively compact, making it a great choice for those with limited rack space.

1. Complexity: The A-106-1 X-Treme Filter has a large number of features and controls, which can be overwhelming for beginners or those looking for a simpler filter solution.

2. Power Consumption: The module consumes a significant amount of power, making it important to ensure that your power supply can handle the load.

3. Price: The A-106-1 X-Treme Filter is a high-end module, and its price reflects its advanced features and build quality.

In conclusion, the Doepfer A-106-1 X-Treme Filter is a powerful and versatile filter module that offers a wide range of features and controls. Its high resonance capability, multiple modulation sources, and flexible control options make it a great choice for synthesists looking to add a high-quality filter to their setup. However, its complexity, power consumption, and price may be drawbacks for some.

If you're looking for a simple, low-power, and affordable filter solution, there may be other options that better suit your needs. However, if you're looking for a high-end, versatile filter with advanced features and a wide range of control options, the Doepfer A-106-1 X-Treme Filter is a strong recommendation.
