Vulgar Display of Power
Quad Cortex is the most powerful floor modeler on the planet. With 2GHz of dedicated DSP from its Quad-Core SHARC® architecture, this ludicrous amount of processing capacity provides limitless sound design possibilities. Want to run four amplifier models, stereo reverbs, and a plethora of other effects simultaneously? Quad Cortex won’t even break a sweat.

Neural Capture
Capture, share and download your favorite rigs’ sounds. Equipped with our unique biomimetic AI technology, Quad Cortex can learn and replicate the sonic characteristics of any physical amplifier, overdrive, and cabinet with unprecedented accuracy. Unlike any other, our sophisticated neural network algorithm perceives sound akin to human perception, making it the most natural-sounding capture solution on the planet. We are collaborating with some of the best producers and sound designers to provide an ever-growing collection of free rig captures in addition to our full-circuit models.

As good as it gets
Quad Cortex packs a vast amount of state-of-the-art emulations of your favorite gear with unprecedented accuracy and unbelievably natural dynamic response.

Cabsim
With over 1000 perfectly captured impulse responses, Quad Cortex ships with one of the most extensive IR collections on the planet – and it is the only of its kind equipped with virtual microphones that can be positioned around the speaker like in a real studio. Third-party IRs are extremely easy to load.

Powerful parametric EQ
Absolute control at your fingertips. Taking full advantage of the 7” multi-touch display, our parametric EQ is intuitive and fun to use. Unparalleled Intuitiveness & Flexibility

Incredible U/I
With its massive 7” multi-touch display, Quad Cortex is unbelievably easy to use. Effortlessly create even the most complex signal paths. Control every feature and function of the Quad Cortex in the same way you control a table or smartphone.

Switching Modes
Switching modes couldn’t be easier, providing easy access to features and switch
customization.
  • Stomp Mode: Assign and activate any block in a rig to a footswitch like you would with an analog pedalboard.
  • Scene Mode: Select any footswitch to instantly activate and control the settings of any number of blocks within a rig.
  • Scene Mode: Select any footswitch to instantly activate and control the settings of any number of blocks within a rig.


Unbelievably Compact
Using advanced mechanical design and manufacturing techniques, we managed to not only build the most powerful floor modeler/multi-effects processor on the planet, we also managed to pack it all in an extremely compact format.

GIG VIEW & SETLIST
Setlists are Quad Cortex’s way of making Presets incredibly easy to organize. A Setlist can contain 32 banks of 8 Presets, and you can create as many Setlists as you like. Setlists allow users to categorize their Presets by band, project, album, or anything else!

We have added Gig View to all modes (Stomp/Scene/Preset), making it even easier to see what's on the display when you're standing above the Quad Cortex.

Gig View allows you to visualize what the footswitches are assigned to instantly. This
visualization utilizes the entire screen.

Components
Quad Cortex comes in a gorgeous anodized aluminum unibody, with laser engraved graphics that never fade. Our multi-touch display is armored with a chemically strengthened protective glass and a reinforced touch sensor panel.
