Example Usage
Novice-level usage example:
Let's say you're working on a music project and you want to add some interesting and unpredictable elements to your composition. This is where the Doepfer A-118-2v Eurorack module comes in handy. With its dynamic noise generation capabilities, you can create unique and ever-changing sounds.
To start, let's focus on the colored noise output. The A-118-2v allows you to adjust the relative amounts of high and low frequencies in the colored noise. By turning the Blue knob clockwise, you increase the proportion of high-frequency components, while turning the Red knob does the same for low-frequency components. Experiment with different settings to find the perfect balance that suits your creative vision.
Now, let's move on to the continuous random voltage. This feature enables you to generate ever-changing control voltages, which can be used to modulate various parameters of your other modules. Adjust the Rate control to change the speed at which the random voltage fluctuates and the Level control to control the intensity or depth of the fluctuations. Pay attention to the dual-color LED display that indicates the polarity of the continuous random voltage, with red for positive and yellow for negative values.
To take things even further, you can utilize the S&H/T&H unit. This unit processes the continuous random voltage signal and produces stepped random voltage output. Set the operation mode to S&H or T&H using the TH/SH switch. When in T&H mode, the output voltage follows the input voltage while the Clock input is high. As soon as the Clock signal changes to low, the last voltage value is stored. On the other hand, in S&H mode, the input voltage is sampled at the rising edge of the Clock signal.
To control the S&H/T&H unit, you need a digital Clock signal, such as a pulse from a clock module or a gate from a sequencer. Connect this Clock input and observe the dual-color LED display connected to the stepped random voltage output. The LED will indicate the polarity of the stepped random voltage, allowing you to further sculpt and shape your composition.
And there you have it! With the Doepfer A-118-2v Eurorack module, you can add dynamic noise generation to your music production arsenal, opening up endless possibilities for sonic exploration. Have fun experimenting and discovering unique sounds that will take your music to the next level.
One interesting way to utilize the Doepfer A-118-2v Eurorack module is in creating evolving percussive sounds. By using the colored noise output and manipulating the Blue and Red controls, you can shape the character of the noise. For example, by increasing the Blue control and decreasing the Red control, you can emphasize the high-frequency component of the noise, resulting in a bright and metallic sound. Conversely, decreasing the Blue control and increasing the Red control will emphasize the low-frequency component, producing a deeper and more resonant tone.
To add movement and variation to the percussive sound, you can connect the continuous random voltage output (RND) to a voltage-controlled filter or any other parameter that responds to control voltages. Adjusting the Rate and Level controls of the random voltage allows you to control the speed and intensity of the modulation. This creates dynamic fluctuations in the filter frequency or any other parameter, adding complexity and interest to the sound.
Furthermore, you can take advantage of the stepped random voltage output (TH/SH) by connecting it to a Clock input of another module. This will generate rhythmic patterns based on the random voltage. Experiment with different Clock signals, such as gates or the rectangle output of an LFO, to explore a wide range of rhythmic possibilities. The stepped random voltage can be used to trigger other modules, creating a synchronized and evolving percussion section within your Eurorack system.
By combining the colored noise, continuous random voltage, and stepped random voltage outputs of the Doepfer A-118-2v, you can create intricate and dynamic noise-based percussive sounds that are full of movement and texture. The module's compact size and efficient design make it an excellent choice for adding exciting noise elements to your Eurorack setup, particularly in situations where space is limited.
Further Thoughts
A fantastic way to utilize the Doepfer A-118-2v Eurorack module's dynamic noise generation capabilities is to add a touch of unpredictability and randomness to your filter modulation. By connecting the continuous random voltage output (RND) to the frequency control input of a filter module, you can create evolving and organic filter sweeps that add movement and complexity to your sound.
First, patch the RND output of the A-118-2v to the frequency control input of your chosen filter module. Next, adjust the Rate control on the A-118-2v to determine the speed at which the random voltage changes. You can experiment with different rates to find the desired amount of modulation.
Now, tweak the Red and Blue controls on the A-118-2v to adjust the balance between low and high frequencies in the colored noise output. This will directly affect the behavior of the random voltage, giving you control over the range and character of the filter modulation.
Additionally, you can use the TH/SH switch to select either sample and hold (S&H) or track and hold (T&H) mode. S&H will sample the input signal at the rising edge of the Clock input, while T&H will track the input signal as long as the Clock input is high and store the last voltage when the clock signal changes to low. Experimenting with these different modes can yield interesting and varied results.
Finally, connect a clock signal (such as a pulse from an LFO) to the Clock input of the A-118-2v. This will determine the timing of the stepped random voltage output (TH/SH), which can be used to trigger other modules or control parameters in your patch.
With this setup, the A-118-2v becomes a versatile and powerful tool for introducing dynamic and evolving filter modulations into your eurorack system. Whether you're creating textural soundscapes or exploring rhythmic possibilities, the Doepfer A-118-2v will add depth and character to your sonic explorations.
