Example Usage

In this example, we'll demonstrate how to use the Erica Synths Black Stereo Delay 2 to create a lush stereo delay effect on a synthesizer riff.

  1. Begin by connecting the audio output of your synthesizer to the input of the Black Stereo Delay 2 module.
  2. Set the mode to "Digital Delay" by turning the mode knob to the desired position.
  3. Adjust the delay time knob to your desired value. For this example, let's set it to around 400 milliseconds.
  4. Increase the feedback knob slightly to add some repeats to the delay. You can experiment with this parameter to find the desired amount of feedback.
  5. To create a wider stereo image, turn the stereo spread knob clockwise. This will spread the delayed signal across the stereo field.
  6. Now, let's add some modulation to make the delay more interesting. Use a CV source, such as an LFO module, to modulate the delay time. Connect the CV output of the LFO module to the CV input on the Black Stereo Delay 2.
  7. Adjust the depth of the modulation by turning the delay time CV control knob. This will determine the range and intensity of the modulation.
  8. If needed, you can also adjust the feedback tone control to shape the tonal characteristics of the delayed signal.
  9. Finally, set the dry/wet mix to your desired balance between the original signal and the delayed signal.
  10. Play your synthesizer and listen to the beautiful stereo delay effect created by the Erica Synths Black Stereo Delay 2. Experiment with different delay times, feedback levels, and stereo spread settings to tailor the effect to your liking.

Remember, this is just a basic example to get you started. The Black Stereo Delay 2 offers much more versatility with its tape and BBD delay modes, as well as other control options like tap and clock synchronization, preset selection, and additional CV control over various parameters. Have fun exploring all the possibilities this module has to offer!

In this intermediate-level usage example, let's explore how the Erica Synths Black Stereo Delay 2 can be used to create a lush stereo delay effect with adjustable spread.

First, let's start by patching a mono audio source into the input of the Black Stereo Delay 2. This could be a synthesizer, drum machine, or any other audio signal you want to apply the effect to.

Next, let's set the delay type to "digital" by turning the corresponding mode selector knob. This will give us a clean and precise delay sound.

Now, we can adjust the delay time using either the dedicated knob or by sending a control voltage (CV) to the delay time input. Experiment with different delay times to find the desired rhythmic effect.

To add some character to the delay, let's increase the feedback using the feedback control knob or by modulating it with CV. Be careful not to go overboard with the feedback, as it can quickly lead to chaotic and self-oscillating sounds.

To widen the stereo image of the delay effect, we can adjust the stereo delay spread control. Start by setting it to a subtle value and gradually increase it until the desired width is achieved. This parameter is particularly useful when working with headphones or stereo sound systems.

Lastly, let's adjust the dry/wet mix to blend the original audio signal with the delayed signal. This allows us to control the intensity of the effect. You can manually adjust the mix knob or use a CV source to dynamically modulate it during your performance.

By exploring different combinations of delay time, feedback, and stereo delay spread, you can create unique and evolving stereo delay effects that add depth and dimension to your sounds. Don't forget to experiment with other delay types like tape and BBD to further expand your sonic possibilities with the Black Stereo Delay 2.

Remember, as with any modular synthesis, the best way to truly understand the module is to experiment and trust your ears. Happy patching!
