Manufacturer's Description from Other

Quad Cortex is the most powerful floor modeler on the planet. With a total of 6 cores (4x SHARC+ and 2x ARM Cortex-A5 running at 500MHz each), 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.

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.

With its massive 7” multi-touch display, Quad Cortex is unbelievably easy to use. Effortlessly create even the most complex signal paths.

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.

Discover Users, Presets, and Neural Captures via the Cortex Mobile app for iOS and Android devices. Linking your Neural DSP account to your Quad Cortex allows you to create backups, share content, and download items from other users. It also unlocks the Impulse Response Library, where you can transfer IRs to your Quad Cortex and manage the IRs stored on your account.
