Breaking: DuoFlux Modulation Plugin Unveiled With Dual-path Processing
A new modulation tool is hitting teh market, promising fresh sonic movement thru four-mode signal splitting. DuoFlux, the latest offering from United Plugins in collaboration with SounDevice Digital, expands on the developer’s prior work with Biverb by bringing a modular, dual‑engine approach to modulation.
At the heart of DuoFlux is a central control that partitions the audio path into four selectable axes: frequency (Low/High), dynamic level (Quiet/Loud), stereo position (Left/Right), and a Mid/Side split. This frequency- and level-based division enables distinct effects to be applied to different parts of a signal, unlocking dynamic sound-design possibilities.
Each side, left and right, functions as its own processor and offers 17 modulation algorithms. Users can fine-tune outcomes with Depth, Rate, Width, Feed, and Character controls. the LFO Shape is fully adjustable, allowing morphing between sine, saw, and square waves by dragging, with an Invert option to reverse the waveform. Like Biverb, DuoFlux includes built‑in high-pass and low-pass filters for each channel.
The standout workflow feature is the ability to run two processors on a single screen without complex routing. While splitting left and right channels is straightforward with many plugins,Mid/Side processing can become intricate,often requiring additional tools to realize different effects across frequency bands or volume ranges.
Sound quality proponents note that,while it may not eclipse dedicated high-end chorus processors on every metric,the plugin’s value lies in its creative potential. DuoFlux is designed to empower experimentation and distinctive textures rather than delivering flawless every-time algorithms.
One notable addition is a Tape section in each unit, which injects analog characteristics into digital sources through saturation, wah, flutter, and noise. While the noise control can feel pronounced at times, the vintage-style chorus and rotary effects add to the plugin’s retro palette.
Visually, the dual interfaces mirror each other, presenting a clean, symmetrical layout. The setup is approachable for those who enjoy experimentation, but the density of controls can overwhelm beginners. Presets help establish the basic mechanics, though some users may find the built-in set fairly modest in variety.
Practical applications abound.For example, applying frequency-based splitting to a synth pad could pair a slow phaser in the lower range with a fast flanger in the upper range for intricate motion. Mid/Side mode on acoustic sounds can widen the stereo field while keeping the core image focused. Volume-based segmentation offers new character traits for vocal processing, allowing subtler modulation on breath or softer sections and more assertive effects on louder passages.
Rounding out the toolkit are user-friendly features: A/B comparison, undo/redo, and 8x oversampling. Advanced options include GUI size tweaks, GPU acceleration, and energy-saving modes during silence via the right-click menu. DuoFlux supports Windows and macOS across VST, AAX, and AU formats.
Pricing and trials are straightforward. The plugin normally retails for 79 euros, but a special launch offer reduces it to 15 euros through the end of February 2026. A 15-day free trial is available for hands-on evaluation.
