Throughout the journey in the Eurorack world, synthesizer enthusiasts frequently grapple with the conundrum of needing specific, small function modules, yet face constraints due to space, budget or both. The Clank Toolbox module ingeniously resolves this issue by housing a host of indispensable functions within its compact 12hp design.
One of the features that awards the Clank Toolbox its utility status is the inclusion of two fast, linear VCAs. VCAs are essential in any Eurorack system for controlling the volume of sound signals and modulations. Having them within arm's reach is a surefire way to encourage more detailed modulation in your patches.
Beneath the VCAs, the Clank Toolbox houses analog/digital mixers that offer summing, inversion, AND and NAND logic operations. This ability opens the door to dazzling rhythmic complexities and sound manipulation by intertwining digital and analog signals. It’s an opportunity to break free from conventional soundscapes and delve into the world of the peculiar and unconventional.
In the center of the module is a bidirectional sequential switch that provides a multitude of functions. Using a gate signal, this switch toggles the right I/O connection between the upper and lower left jacks. This interchanging ability allows for either 2:1 or 1:2 configurations, making the sequential switch a potent tool that allows breath-taking evolutions within your patches.
A pair of flip-flops, classics in digital synthesis, lie to the right of the sequential switch. // The presented flip-flops output a square wave at half the frequency, thus facilitating sub-octave creation or clock division when handed an audio or gate signal. This block alone can bring forth rhythmic sophistication inherently found within complex modular systems.
Perched at the bottom are offset and attenuverting channels. // Proving indispensable when refining tuning of an oscillator or controlling the depth of a modulation, these units can manipulate the polarity or amplitude of the incoming signal. Coupled with the insertion of positive or negative offset, the user taps into a vast cosmos of sonic sculpting possibilities.
Parallel to the offset controllers is the Sum/Multiplier block, boasting two 3-channel summing blueprints whose collective sum is actively multiplied. This mechanism accommodates a broad array of configurations revolutionizing patch dynamics with proportionally assigned outputs based on how many inputs are utilized.
On the frontier of sound experiments, the Clank Toolbox features a threshold parameter that morphs the operators' behavior in all logic functions marked with an asterisk. By merely adjusting this CV-based parameter, you can revive any stagnant sound design with exhilarating change, transforming even the most basic LFO patterns into unrecognizable waveforms of sonic wonder.
A testament to the Clank Toolbox’s charm is its internal interaction design, facilitating enthralling outcomes from combinations of its various functional blocks. This single module reasserts the idea that the Eurorack Platform, though purely analog, possesses infinite sonic possibilities through modularity and parameter interactivity.
Example Usage
For those just stepping into the world of Eurorack and eager to explore the potential of the Clank Toolbox module, here's a simple exercise to get you started and inspire creativity with this versatile tool. Start by utilizing the two VCAs located at the top of the module. Connect the output of your favorite oscillator to one VCA input and control its amplitude with a basic envelope generator. This setup will let you familiarize yourself with amplitude modulation, an essential technique in sound design.
Next, explore the analog/digital mixers. Feed two waveforms, such as a sine wave and a square wave from different oscillators, into the channels of the mixer. Experiment with summing, inverting, and applying logic operations like AND and NAND. By manipulating these signals, you'll understand how combining and altering waveforms can lead to the creation of unique rhythms and textures that are foundational to cool synth leads and bass lines.
Move on to the bidirectional sequential switch. Take a simple clock pulse and experiment with using it to toggle signals or audio between different destinations. By switching between two targets, you can introduce variability into your patches, creating dynamic movements or complex polyrhythms that breathe life into your sequences.
Leverage the flip-flops to create simple sub-octaves. Input a wave or clock signal and observe how the flip-flop outputs a square wave at half the input frequency. Engage these flip-flops with the earlier VCA setup to construct deep, rich bass tones or play with clock division to tweak timing relations within your patch.
Finally, introduce the offset and attenuverting functions to refine control over your CV signals. Utilize these to shape the behavior of modulation sources or introduce subtle changes to your audio signals, honing precision in your patches. Understand how adjusting offsets influences the characteristics of a modulation, leading to nuanced control over pitch, timbre, or rhythmic patterns.
By undertaking these simple exercises, you'll unlock fresh perspectives on integrating utility with creativity, enriching your patching experience with the clank-toolbox, and laying the groundwork for more advanced configurations down the line. As you become comfortable with these basic applications, you'll soon find innovative ways to combine the functions of the Toolbox, elevating your sound design capabilities.
To unlock the full potential of the Clank Toolbox, let’s explore an intermediate-level patch that combines multiple functions of the module to create a complex rhythmic texture while adding harmonic interest to an audio signal. Start by using the VCAs for amplitude modulation. Patch an LFO or a slow-moving CV to one VCA’s control input while routing an audio signal, perhaps from a simple oscillator, to the VCA’s signal input. This can produce evolving dynamics on your sound, as the VCA rhythmically controls the audio level.
Next, utilize the bidirectional sequential switch to inject variety and interest into your rhythm. By routing a gate sequence to the switch’s control input, you can dynamically swap audio paths or CV inputs, making the rhythm unpredictable and engaging. If your aim is to sequence diverse sources, feed different audio textures or CV sources into the available I/Os to morph the rhythmic landscape on-the-fly.
The flip-flop section offers an excellent opportunity for harmonic exploration. Take the output from one of your oscillating sources and feed it into a flip-flop block. This will generate a square wave output at half the original frequency, introducing a sub-octave that enriches your patch. If you chain both flip-flops in series, you can create two sub-octaves, opening up rich, bass-heavy possibilities.
Consider integrating the analog/digital mixer to blend and creatively reshape your signals. Route the outputs from both the VCA-modulated audio and the flip-flop-generated sub-octave into one of the mixer channels. Employ the AND or NAND functionality to further sculpt the interaction between these signals based on their peaks and troughs, creating a layered and complex audio pattern.
Finally, refine and control your patch using the offset/attenuverter block. Adjust the offset and polarity of your LFO before sending it into the VCAs. Additionally, modulate the threshold parameter to fine-tune how the logic operators respond, sculpting the rhythmic patterns to adapt to your evolving generative melody.
By weaving together these features, the Clank Toolbox elevates your Eurorack system's capability to produce intricate, self-evolving patches that challenge traditional boundaries, positioning this utility module not merely as a problem solver but as an indispensable idea enhancer in your sonic toolkit.
