The ADVA 3U from Plum Audio is more than simply an analog multimode filter; it's a compact powerhouse of sound innovation that draws upon plethora of features to create a wide range of rich and immersive tones.
Boasting seven filter modes, the ADVA 3U adeptly explores sonic territories ranging from the subtle harmonics of a low-pass gate (LPG) to the ferocious bite of hot acid tones. As a defining feature, a unique phase keeper function ensures the input’s phase always remains consistent, regardless of the selected filter mode - a characteristic not commonly found in many multimode filters.
Additionally, the inbuilt self-oscillation feature, available across all modes, offers a spectrum of waveforms, from the pure simplicity of sine waves, extending to the rich textures of soft square waves when the post-distortion circuit engages. This, in combination with Volt per Octave (V/OCT) tracking, paves the way for ADVA 3U to excel both as an oscillator and a percussive sound generator.
Integral to ADVA 3U’s sound crafting capability, the incorporation of a resonance loudness compensation circuit guarantees the module maintain its volume even when resonance is cranked up, a handy feature to bypass the often-encountered volume drop in other modules with increased resonance.
The internal analog white noise generator of ADVA 3U is like the secret ingredient in a masterchef's recipe that subtly brings out the beauty of the dish. This generator, by means of a dedicated knob, invites you to blend it with the input signal, adding a layer of intricacy to your sound while underlining cutoff movements. More creatively, it can also be utilized as a Frequency Modulation (FM) source to bring forth a highly eclectic realm of dirty tones.
Delving further into the world of grit and saturation, ADVA 3U features two distinct distortion circuits that push the boundaries of sound design within such a compact module. The first circuit offers soft-clipping overdrive, positioned post white noise blend and input gain knobs. This is capable of adding thickness to an incoming signal, with the possibility to further exaggerate and compress the noise when blended with the noise generator. The second circuit, known as the Post Distortion, is located post Voltage Controlled Amplifier (VCA) and is known to produce some seriously aggressive, acid tones.
Complementing its entirely analog sound path, the ADVA 3U employs a digital support circuit that introduces a smart routing system. This novel addition enables modulation of filter modes via Control Voltage (CV). The interface of ADVA 3U is designed to be intuitive and welcoming, showcasing three CLICKKNOBS and an RGB LED ring that doubles as a visual feedback system, making it easier to identify the current state of the filter.
To sum it up, the ADVA 3U is a veritable audio modulation 'Swiss Army Knife', capable of creating a huge variety of filtering effects, oscillations, and distortions. It offers an undeniably distinct blend of suite features and a convenient form-factor, all contradicted within a smart intuitive interface. Its extensive CV control, self-oscillation, phase keeper and dual distortion circuits make it a must-have in any Eurorack system. Whether you're after some gentle filtering or hardcore, distorted acid tones, ADVA 3U is certain to satisfy your sonic cravings.
Example Usage
Novice Usage Example: Imagine you have a basic setup with a sequencer and a couple of oscillators. You want to add some flavor to your sounds by using a versatile filter module. Enter the ADVA 3U!
First, connect the output of one of your oscillators to the input of ADVA. Adjust the cutoff frequency knob to set the starting point for the filter. Now, start exploring the different filter modes. Turn the mode knob and listen closely to how the sound changes. You'll notice that each mode has its own unique character and tone.
To make things more interesting, try adding some resonance. As you increase the resonance knob, the filter will start to emphasize certain frequencies, giving your sounds a more focused and intense quality. Experiment with different resonance settings to find the sweet spot for your music.
But we're not done yet! ADVA also has a built-in white noise generator. Turn the blend knob to mix in some white noise with your input signal. This will add texture and richness to your sound, making it more dynamic and expressive.
Now, let's explore the distortion circuits. The soft-clipping overdrive can be enabled by turning up the gain knob. This will give your sound a warm and saturated character, perfect for adding some grit to your basslines or lead sounds. If you want to go even further, engage the post-distortion circuit for some aggressive and dirty tones.
Throughout your experimentation, don't forget to play with the modulation options. ADVA allows you to modulate the filter modes via CV, opening up endless possibilities for evolving and dynamic sounds. Connect a modulation source, like an LFO or an envelope, to the CV input and witness how the filter modes come to life, adding movement and interest to your music.
In conclusion, the ADVA 3U is a powerful and versatile filter module that can take your sound design to the next level. Whether you're a novice or an experienced synthesist, this module offers a wide range of sonic possibilities. So go ahead, unleash the versatility of the ADVA 3U and let your creativity soar!
