Unveiling the versatility of tonal dimensions, the Triple Window Comparator, often known as the heart of Eurorack innovation, offers modular enthusiasts a playground for exploring spectrum creativity. This module, a product by Nonlinearcircuits, is brandishing an excitingly intricate fusion of art and science aboard its electronic circuits. Hosting three exclusive window comparators, the Triple Window Comparator module allows its users to curate unique sounds, extracting the providence of gate or timed events using chaos signals. Additionally, the module embellishes pulse width modulation at audio rates, creating an exhaustive repository of unparalleled sounds.
The craftsmanship of the Triple Window Comparator breathes life into the observant acumen of H.K Verma, as depicted in his insightful paper, "Some Special-Purpose Comparator Circuits." Albeit with a few tweaks to accommodate the sophisticated needs of the contemporary Eurorack space, the module exemplifies a distinctive semblance to the concepts in Verma's paper.
The first of these comparators, the "Special Comparison Instant," operates as a conventional window comparator. The facility of this circuit allows users to allocate the high and low voltages creating an output gate, which will be high in between these settings. Remarkably, you can seamlessly integrate CV signals to alter the high and low configurations.
Our second stop on this fury of sounds is the "Comp for Concurrent Magnitudes." This comparator uniquely operates on the premise of comparing the signal on Input 1 against the setting of the SET/In2 pot. In the absence of a signal on In 2, the pot sets a fixed voltage. Alternatively, the signal on In 1 can be compared with the amplitude of the signal on In 2 if present, and the pot attenuates as needed. It doesn't stop there; the level pot in this circuit can be used to set the gate level, offering up to 10V! And by patching an input into the LEVEL input, you can give rise to envelopes or bursts rather than gates.
Lastly, we look into the "Comp for Restricted Openings." This ingenious feature comes with the luxury of a pot (WIDTH) or CV control to define and change the gate width. Further, In1 and In2 are summed together and measured against the level selected with the SET pot.
The build process is succinctly simple with a recommendation for users to use super-bright LEDs. These LEDs should ideally be bent slightly upwards to cast light through the windows from the bottom, this aids the correct illumination of the individual circuits within the module.
This Eurorack module brings a new solution to sound synthesis, helping users project their music in a way that caters specially to their specific preference. So whether you're an enthusiast looking to dabble with some new sounds, a professional producer seeking a unique kick, or a hardware geek eager to illuminate your rig with super-bright LEDs, the Triple Window Comparator provides a path to your Eurorack exploration.
Example Usage
To use the Triple Window Comparator module, you can start by exploring the three individual window comparator circuits included in the module. Each circuit operates uniquely, offering diverse possibilities for shaping your sound.
The "Special Comparison Instant" circuit functions as a standard window comparator, allowing you to set high and low voltage thresholds for triggering the output gate. Experiment with patching in CV signals to modulate these settings and generate dynamic results.
Next, engage with the "Comp for Concurrent Magnitudes" circuit, which compares signals on Input 1 against the setting of the SET/In2 pot. Adjust the amplitude of the comparison signal with the pot or by patching in an external signal. Utilize the Level pot to control gate levels or introduce signals to the LEVEL input for crafting envelopes or bursts.
Finally, interact with the "Comp for Restricted Openings" circuit, where you can set and modify gate width using the WIDTH pot or CV control. Blend signals from In1 and In2, comparing them with the level set by the SET pot to achieve nuanced outcomes.
When assembling the module, ensure the LEDs are slightly bent upwards to illuminate the windows effectively. Opt for super-bright LEDs to guarantee optimal visibility through the PCB panel. Experiment with these features to unlock a world of creative sound design possibilities.
In this example, let's explore how to use the Triple Window Comparator module in a more advanced way.
One interesting way to utilize this module is by creating evolving rhythmic patterns using the Comp for Restricted Openings circuit. By patching a complex LFO signal into Input 1 and a slower clock signal into Input 2, you can manipulate the gate width with the WIDTH control or CV input. Experimenting with different modulation sources and adjusting the gate width can yield intricate rhythmic variations that can add a dynamic element to your music production.
Additionally, you can take advantage of the Comp for Concurrent Magnitudes circuit to generate dynamic envelope shapes. By inputting a percussive signal into Input 1 and a modulation source (such as a random stepped voltage) into Input 2, you can use the Level pot or an external CV signal to shape the amplitude of the output envelope. This can be particularly useful for creating evolving pad textures or percussive accents with varying levels of intensity and duration.
These techniques showcase the versatility of the Triple Window Comparator module in generating complex and evolving sonic textures. Experimenting with different signal combinations, modulation sources, and control settings can lead to a wide range of unique sounds and musical possibilities.
Further Thoughts
To make the most out of the Triple Window Comparator module, experiment with patching chaotic signals into the inputs and adjusting the settings to create unique gate/timed events. Utilize the Special Comparison Instant circuit for standard window comparison tasks, and explore the Comp for Concurrent Magnitudes for dynamic comparisons between signals. Additionally, delve into the capabilities of Comp for Restricted Openings for precise control over gate width modulation. Don't forget to use super-bright LEDs for optimal performance and consider incorporating external signals for further sonic exploration.
