01Overview

DuoFlux is built around the idea that two modulators working together can do what one cannot. Each of its two modulation units has its own set of controls, including Rate, Depth, Width and Character, plus adjustable LFO shapes from sine to square. A crossover decides how the incoming signal is divided between the two units, so each unit can process a different part of the mix. The developer describes it as a tool for adding depth and movement to mixes and soundscapes, and it is offered as a fully functional trial for 15 days.

Splitting the Signal Between Two Modulators

The crossover is the core of DuoFlux. It can divide the signal by Frequency, Volume, Stereo or Mid/Side, and each path is processed separately before the results are combined.

Mid/Side mode lets you keep the center focused while applying movement to the sides, for example a chorus on the sides with the mid channel left untouched. Left/Right mode sends one type of modulation to each channel for wide, extreme effects at the edges of the mix. In Left/Right mode the Width control is disabled to keep channel separation precise.

Quiet/Loud mode splits the audio at a loudness threshold set by the Crossover dial, so the two units can move the quiet and loud parts of a sound in different ways.

Algorithms and Tape Character

Each unit offers 17 modulation algorithms. The developer names a Vintage Chorus and Ensemble for lush width, a Modern Rotary for swirling motion, and Tremolo and Phaser for rhythmic pulse. Layering two units lets you combine these textures.

Each unit also has a Tape section with Saturation, Wow and Flutter modulation, and Noise for head scrape and dust. This allows one unit to stay clean while the other adds vintage wobble, for example clean modulation on the lows and tape character on the highs.
