The DuoFlux Black Friday deal from United Plugins takes 81% off this dual-modulation plugin, bringing it to $15 until Nov 29, 2026.

DuoFlux puts two independent modulation units inside one plugin, so you can run two different movements on the same sound.

What does DuoFlux do?

A crossover splits the incoming signal between the two units. Each unit then processes its share on its own, and you can set the split four ways:

  • Frequency
  • Volume
  • Stereo
  • Mid/Side

That lets you give the lows clean modulation while the highs get something wobblier.

17 algorithms in each unit

Every unit draws from the same set of 17 modulation algorithms. The maker lists Vintage Chorus, Ensemble, Modern Rotary, Tremolo and Phaser among them.

Parameters include Rate, Depth, Width and Character. LFO shapes run from sine to square, and you can layer the two units to build evolving textures.

Tape section on each unit

Both units carry their own Tape section, so one side can stay clean while the other picks up vintage colour. It covers three things:

  • Saturation
  • Tape-style Wow and Flutter modulation
  • Noise, which the maker describes as simulating head scrape and dust

Sometimes the only difference between the units is a small change in saturation.

Split modes in detail

Mid/Side separates the centre from the sides, so you could run a chorus on the sides while the mid stays focused. Left/Right sends one modulation to each channel, and the Width control is disabled in that mode to keep the channels strictly separate.

Quiet/Loud splits the audio at a loudness level set by the Crossover dial. The quiet and loud parts then get independent movement.

Under the hood

DuoFlux processes internally at 64-bit and handles any sampling rate, including 192 kHz and higher. Smart bypass avoids clicks when you automate the parameter and compensates for latency.

Intelligent sleep on silence drops the plugin's CPU use to virtually nothing when there is no signal to process.

Licensing and trial

Activation uses license files. DuoFlux skips iLok, dongles and online checks, and you can run it on every machine you own so long as you're the one using it.

United Plugins offers a free 15-day unlimited trial with no saving limits and no added noises. Updates are free for life, so you can always move to the newest version without paying again.

DuoFlux Black Friday deal: questions

Is DuoFlux on sale for Black Friday?

Yes. The DuoFlux Black Friday deal takes 81% off, so the plugin costs $15 until Nov 29, 2026. It is United Plugins' dual-modulation plugin with two independent units, 17 algorithms in each and a Tape section on both.

How does DuoFlux split the signal between its two modulation units?

A crossover feeds the two units and can be set to Frequency, Volume, Stereo or Mid/Side. The maker also lists Left/Right and Quiet/Loud splitting, where the Crossover dial sets the loudness threshold. Each unit processes its portion independently.

What modulation types does DuoFlux include?

Each of the two units offers 17 algorithms, including Vintage Chorus, Ensemble, Modern Rotary, Tremolo and Phaser. You can adjust Rate, Depth, Width and Character, pick LFO shapes from sine to square, and layer both units together.

Does DuoFlux need an iLok or internet to activate?

No. United Plugins activates with license files, so there is no iLok, dongle or internet connection involved. You can use the software on all your own computers. A free 15-day unlimited trial is available, and updates are free for life.
