Review DOEPFER Wave Multiplier

The Doepfer A-137-1 Wave Multiplier is a versatile and intriguing module in the world of modular synthesis. This module is designed to take a single sine wave input and generate multiple harmonically related outputs, effectively creating a complex waveform from a simple one.

At its core, the A-137-1 is a sine wave generator that can be set to a user-defined frequency through the CV input. The module's magic lies in its wave multiplier section. This section consists of a series of voltage-controlled frequency dividers, each capable of dividing the input frequency by a factor between 2 and 12. The output of each divider is then routed back into the input of the next divider, creating a chain reaction of frequency division.

The result is a series of harmonically related outputs. For example, if the input frequency is 440 Hz (A4), the first output might be the fundamental (440 Hz), the second output might be the octave (220 Hz), the third output might be the fifth (330 Hz), and so on. These outputs can be used independently or combined to create complex and rich waveforms.

The A-137-1 also features a waveform select input that can be used to modify the output waveform. When this input is set to 0V, the module generates only odd harmonics. When it is set to a positive voltage, even harmonics are also generated. This allows for a wide range of waveform possibilities, from pure sine waves to complex, harmonically rich waveforms.

The module's front panel is cleanly laid out, with clear labeling of each input and output. The CV inputs and outputs are each equipped with attenuators, making it easy to fine-tune the module's settings. The module also includes a trigger input, which can be used to synchronize the output waveforms to external clock sources.

In summary, the Doepfer A-137-1 Wave Multiplier is a powerful and flexible module that can generate a wide range of complex waveforms from a simple sine wave input. Its wave multiplier section allows for the creation of harmonically rich outputs, while its waveform select input adds an extra layer of versatility. With a clean and intuitive front panel, the A-137-1 is an excellent choice for any modular synthesist looking to explore the world of complex waveforms.

The Doepfer A-137-1 wave multiplier is a versatile and intriguing module for synthesizers, offering the ability to generate complex waveforms from a single input signal. Here are some pros and cons to consider before making a purchase:

1. Wide range of waveform generation: The A-137-1 can generate a variety of complex waveforms, including harmonics, subharmonics, and irregular waveforms. This can add depth and interest to your synthesizer sounds.

2. Flexible modulation options: The module offers multiple ways to modulate the waveform, including CV input, envelope follower, and sync input. This allows for a high degree of expressiveness and control.

3. Compact size: The A-137-1 is a relatively small module, making it a good choice for those with limited space in their synthesizer setup.

4. Affordable price: Compared to other wave multiplier modules, the Doepfer A-137-1 is relatively affordable, making it a good option for beginners or those on a budget.

1. Complexity: The A-137-1 can be a complex module to understand and use, especially for those new to synthesis. It may require some experimentation and learning to fully utilize its capabilities.

2. Limited input options: The module only has one input, so it may not be suitable for those looking to process multiple signals at once.

3. Power consumption: The A-137-1 consumes a fair amount of power, so be sure to check that your power supply can handle it.

The Doepfer A-137-1 wave multiplier is a powerful and versatile module that can add a lot of depth and complexity to your synthesizer sounds. Its flexible modulation options, wide range of waveform generation, and compact size make it an attractive option for many synthesists. However, its complexity may make it a challenging module for beginners, and its limited input options may not be suitable for those looking to process multiple signals at once. Ultimately, if you're looking to add some unique and intriguing sounds to your synthesizer setup, the A-137-1 is definitely worth considering.

If you're interested in the Doepfer A-137-1 wave multiplier, I would recommend doing some research and experimentation before making a purchase. Watch some tutorials and read up on wave multipliers in general to get a better understanding of their capabilities and how they can be used to enhance your synthesizer sounds. Additionally, consider whether the module's limitations, such as its complexity and limited input options, will be a good fit for your synthesizer setup and goals. If you're still unsure, you may want to consider renting or borrowing the module to try it out before making a purchase.
