Example Usage

In this example, let's explore how the Knob Technology SGR1806-20 can be used to create a dynamic and evolving soundscape.

First, let's start by patching the SGR1806-20 into our Eurorack system. Connect the audio output of the SGR1806-20 to a mixer or audio interface for sound playback.

To begin, set up a basic patch by sending a gate signal to the SGR1806-20's envelope input. This will trigger the percussion sound. Adjust the envelope settings to your liking, experimenting with different decay times and curve shapes. This will shape the overall character of the sound.

Next, let's focus on the V block, which consists of three triangle oscillators. Start by adjusting the frequency and waveform knobs to find a base tone that fits your desired soundscape. You can experiment with detuning the oscillators slightly for a richer and more interesting sound. Use the crossfade VC mixer to blend the outputs of the V block oscillators.

Now, let's introduce some noise into our soundscape using the N block, which consists of three noise oscillators. Adjust the frequency and character knobs to generate different types of noise textures. Use the crossfade VC mixer to blend the noise with the V block oscillators, creating a unique sonic combination.

To add further complexity to our soundscape, let's engage the wavefolder/waveshaper and distortion features. These modules introduce dynamic timbral transformations by folding and distorting the incoming sound. Experiment with different settings to achieve distortion effects ranging from subtle overdrive to intense saturation.

To finalize our evolving soundscape, we can modulate various parameters using control voltages (CV). Consider patching an LFO or an envelope generator to modulate the V block frequency, N block frequency, crossfade VC mixer, or the wavefolder/waveshaper and distortion controls. This will introduce movement and variation to the sound over time.

Remember, soundscapes can be highly subjective, so don't be afraid to experiment and explore different settings and patch configurations. The Knob Technology SGR1806-20's flexibility and analog sound engine provide a rich palette of possibilities for creating captivating and immersive soundscapes in your Eurorack setup.

In this example, we will explore how the Knob Technology SGR1806-20 can be used to create dynamic soundscapes within a modular synthesis setup.

  1. Start by patching an LFO output to the V block's frequency input. This will modulate the pitch of the triangle oscillators over time, adding movement and variation to the sound.
  2. Connect the output of the V block to a filter module that offers resonant filtering capabilities. Experiment with different filter types and cutoff frequencies to sculpt the sound of the triangle oscillators.
  3. Patch one of the noise oscillators from the N block to the Smooth V to N crossfade VC Mixer. Adjust the crossfade control to blend the triangle and noise oscillators smoothly, finding the perfect balance between tonal and noise components.
  4. Use the Wavefolder/waveshaper and Distortion section to add harmonically rich overtones and distortion to the sound. Experiment with different shapes and distortion parameters to sculpt the timbre to your liking.
  5. Connect an ADSR envelope module to the SGR1806-20's envelope input. Modulate the envelope's attack, decay, sustain, and release parameters to shape the amplitude and contour of the sound. Experiment with logarithmic and exponential curves to create evolving soundscapes.
  6. Further shape the sound by patching modulation sources such as additional LFOs or envelope generators to control various parameters of the SGR1806-20, such as the wavefolder amount or the crossfade balance.
  7. Integrate the SGR1806-20 into your modular setup, combining its sound with other modules to create a complex and evolving soundscape. Explore different patching configurations, routing the SGR1806-20 through effects modules, or processing its output with reverbs, delays, or granular effects to add depth and space.

By experimenting with the Knob Technology SGR1806-20's features and integrating it creatively into your modular synthesis setup, you can unlock a vast sonic palette for crafting immersive and evolving soundscapes.

Further Thoughts

One powerful way to utilize the Knob Technology SGR1806-20 analog drum synthesizer is to create complex soundscapes that transport listeners to new sonic dimensions. By harnessing the module's versatile features, you can craft immersive and evolving textures that captivate and inspire.

Start by patching the V block's three triangle oscillators into the Smooth V to N crossfade VC Mixer. Adjust the oscillator frequencies and mix levels to create a foundation of rich harmonic content. Experiment with different wave shapes and introduce subtle modulation to add depth and movement to the sound.

To further enhance the sonic landscape, engage the N block's three noise oscillators. These noise sources can be utilized to add both texture and atmospheric elements to the composition. Adjust the noise parameters, such as color and density, to shape the character of the noise. Consider using envelope modulation to introduce subtle variations and dynamic changes, adding an organic touch to the sound design.

For a more experimental approach, take advantage of the SGR1806-20's wavefolder/waveshaper and distortion capabilities. These features allow you to sculpt and shape the sounds, adding grit, distortion, and harmonic complexity to your sonic explorations. Carefully tweak the wavefolder and distortion parameters to find the sweet spot that complements the overall texture.

To add movement and evolution to your soundscapes, utilize the built-in envelope with a log/antilog curve. Modulate various parameters such as oscillator frequencies, mix levels, or filter cutoff using the envelope generator. This dynamic modulation adds a sense of progression and transformation to your sound design, evoking a sense of movement and life within the composition.

As you delve deeper into sound design with the Knob Technology SGR1806-20 analog drum synthesizer, consider exploring the module's CV inputs and outputs to integrate it with other Eurorack modules. By connecting it to a sequencer, modulation source, or effects processor, you can further expand the creative possibilities and unleash even more intricate soundscapes.

In conclusion, the Knob Technology SGR1806-20 analog drum synthesizer is a powerhouse module that goes beyond traditional drum synthesis, offering a platform for crafting awe-inspiring soundscapes.
