DUPTRAX 3Guitar Double Tracker
Record your part once. DupTraX 3 plays it again, the way you would on a second take: a little ahead or behind on every note, its own intonation, its own picking. Learned from real double-tracked guitars — and in our blind tests, it’s very hard to tell apart from the real thing.
Best on DIWorks best on a clean DI guitar track. Put DupTraX 3 before your amp sim, so every take goes through the amp like a real double. See how to connect it

Tutorial
Every feature in 8 minutes
A tour of the real plugin with real guitar DI tracks playing through it: where it goes in your chain, the takes view, presets, Double and Quad, the feel controls, an amp sim on every take, and playing live in the standalone app.
Signal routing
Every take through its own amp
A real double is two performances, each through its own amp, panned in the mix. DupTraX 3 goes before your amp sim, on the clean DI guitar. Pick how you work and watch the takes flow.
Blind test
Can you tell which one is the real second take?
A guitarist recorded each riff twice. In every pair below, the left side is his first take. The right side is either his real second take — or DupTraX 3, playing a second take from the left one. Both go through the same 5150-style amp profile and a Marshall 4x12 V30 cab, at the same level. Put on headphones, listen to A and B, and pick the real one.

A second take is a second performance
When you double a part, your second take is never a copy. Some notes land early, some late, each is a hair differently in tune, picked a little harder or softer. A delay, a chorus or a copied track can't do that — DupTraX 3 does it note by note, from what it learned listening to guitarists play the same parts twice.

Double and Quad
Two guitars, or a wall of four
Double plays one new take against yours: the classic left and right rhythm guitars. Quad plays three new takes, two guitars on each side: your take and take 1 hard left and right, takes 2 and 3 a little inside, like a real quad-tracked wall. Every take plays the part its own way, and you can move each one where you want it, right on its lane.
14 presets
From surgical to sloppy, in one click
Natural Double, Tight Metal Rhythm, Djent Surgical, Loose Rock, Live Feel, Clean Strum, Wide Quad Wall, Lead Double, Mono Thick and more. Save your own and they come with you into every project.
Live mode
Play through it, with zero latency
Turn on Live and your guitar comes through instantly while the doubles follow just behind you, like a second player standing next to you. The app shows the whole delay from your guitar to your ears, so you can set your buffer with confidence.
Standalone app
Your guitar and your amp sim, no DAW
Plug your guitar into your audio interface, load your own VST3 or AU amp sim right inside the app and play. Every take goes through the amp on its own, the way real double tracks are recorded, and DupTraX pans them afterwards. Run your amp sim in Stereo (set it to its stereo mode) or in Mono, one copy per take. If your amp sim mixes the two sides into one, the app tells you and fixes it with one click. ASIO on Windows.
Your feel
As tight or as loose as you play
Every control starts where real guitarists are. Turn it to taste.
TightnessFrom an edited, session-tight double to two players loosely in one room.
TimingHow far each note moves ahead of or behind yours.
PitchHow differently in tune each note is, like a second take on a real guitar.
Dynamics and toneHow much harder or softer each note is picked, and how its tone changes with the stroke.
Pan, width and levelPlace every take where you want it. Width brings them all towards the centre, down to one fatter mono guitar.
Double onlyMute your original and print the new take on its own track.

Questions
Frequently asked
What is DupTraX 3?
DupTraX 3 is a double tracker for guitars. From one recorded take it plays a second take of the same part, or three more in Quad, the way a guitarist plays a part again: a little earlier or later on each note, with its own intonation, picking strength and tone. It is not a delay or a chorus.
Does it really sound like a second take?
That was the goal and the test. We recorded real double-tracked rhythm guitars, played the second take and the DupTraX 3 double through the same amp, and asked which one was real. In our blind tests the double was very hard to tell apart from the real second take. Try it yourself in the blind test on this page.
What is the difference between Double and Quad?
Double plays one new take, panned against your original: the classic left and right rhythm guitars. Quad plays three new takes, so one recorded part becomes a wall of four rhythm guitars. Each take plays the part in its own way.
Can I play live through it?
Yes. Turn on Live and your guitar comes through with zero latency while the doubles follow just behind you, like a second player in the room. The standalone app runs without a DAW and supports ASIO audio interfaces on Windows.
Can I use my own amp sim in the standalone app?
Yes. Click Amp in the app and load your VST3 amp sim (on a Mac also Audio Unit). Every take goes through the amp on its own, the way real double tracks are recorded, and DupTraX pans the takes afterwards. In Stereo mode one copy of the amp plays each pair of takes, so set your amp sim to its stereo mode; in Mono mode every take gets its own copy, which works with any amp sim. If your amp sim mixes the two sides into one, the app tells you and switches to Mono with one click. You set the amp in its own window once; the other copies follow.
I own DuptraX or DuptraX Pro. Is there an upgrade price?
Yes. Log in with the account you bought it with and 30 % comes off DupTraX 3 at checkout automatically. There is no code to enter. This upgrade offer ends on 31 October 2026 at 23:59 CET. It will not continue into November or return in December.
Which formats and systems does it run on?
VST3 and the standalone app with ASIO on Windows 10 and 11 (64-bit), and VST3, Audio Unit and the standalone app on macOS 11 or newer, on Intel or Apple Silicon. Pro Tools (AAX) is not supported. The download includes installers for Windows and macOS and the User Guide.
Where do I put it: before or after my amp sim?
Before. DupTraX 3 works best on a clean DI guitar track: put it first, then your amp sim. On one track, run the amp sim in its stereo mode if it has one, so your take and the double each go through the amp on their own side; if the amp sums to mono, the double collapses into one guitar. To give every take its own amp in any DAW, copy the DI to one more track (three more for Quad) and put DupTraX 3 on each copy with Double only and a different Take number; the user guide shows it step by step. In REAPER you can also switch DupTraX 3 to Separate outputs and send each take to its own amp track. In the standalone app DupTraX does all of this for you with your amp sim.
Does it work on vocals or bass?
DupTraX 3 is made for guitar: it learned from guitarists playing the same part twice, and that is where it sounds its best. Use it on rhythm and lead guitar, clean or distorted.
