Workstation for Guitar and Bass

Thanks to the huge selection of high-quality amp simulations, numerous effects and the intuitive operation via the touchscreen display, the Neural DSP Quad Cortex is the all-in-one, everywhere solution for the modern musician. Alongside the excellent sound, the Neural Capture technology and the constantly growing sound library, the versatile connectivity and seamless integration into almost any setup are at the heart of the Quad Cortex.

Connections of the Quad Cortex

  1. Two mono combo input jacks: TS, TRS and XLR with variable impedance and level control. Built-in microphone preamps and phantom power
  2. Two effect send-return paths: for integrating external mono and stereo effects or additional line ins/outs.
  3. Two mono outputs (balanced line)
  4. Two mono outputs (balanced XLR)
  5. 6.3 mm headphone jack
  6. MIDI In/Out/Thru: Parameters in the Quad Cortex and other connected MIDI-capable devices can be automated via the protocol.
  7. Two connections for expression pedals: for example to control wahs, volume or pitch-shift algorithms.
  8. USB port: for connection to a PC as an audio interface, for data transfer, updates, etc.
  9. 11 high-quality stainless steel footswitches that double as rotary push-encoders for operating the Quad Cortex.

Neural Capture Technology

With the Quad Cortex you can capture, share and download the tones of favourite amplifier setups. The unique biomimetic AI technology enables the unit to learn and replicate the tonal characteristics of physical amplifiers, overdrive effect pedals and cabinets with unprecedented realism.

Unlike other solutions, the advanced neural network algorithm uses a perception of sound similar to the human one. This makes the Quad Cortex the most naturally sounding capture solution worldwide. In addition to the full-circuit models, Neural DSP works with some of the best producers and sound designers to offer a constantly growing collection of free rig captures!

Incredibly Compact

By using advanced mechanical design and manufacturing techniques, Neural DSP succeeds not only in building the most powerful floor modeler / multi-effect processor in the world, but also in fitting it into an extremely compact and robust format.

Dimensions: 29 x 19 x 4.9cm

 Weight: 1.95KG / 4.2lbs

Cortex Cloud

Discover other users, presets and Neural Captures via the Cortex mobile app for iOS and Android devices. By linking a Neural DSP account with the Quad Cortex you can create backups, share content and download items from other users. Access to the Impulse Response Library is also unlocked. From there, IRs can be transferred to the Quad Cortex and the IRs stored on an account can be managed.

Important Quad Cortex Firmware Updates at a Glance

2.3.1 CorOS and Cortex Control 1.0.1 updates

You can find all information about the new updates here.

2.0.0 CorOS Update: Hybrid Mode and more!
The Hybrid Mode can be customised via the new "Mode Configuration" option in the main menu. Each footswitch can be assigned a separate operating mode. Hybrid Mode is designed for musicians who want quick access to new presets while keeping granular control within their active preset by incorporating Stomp Mode or Scene Mode. A Hybrid Mode can be created from one of the three available modes. You can also remove modes you no longer use to switch between three, two or just one active mode!

Other updates include a global bypass for cabinet or impulse-response simulations (Cab/IR), a master equalizer (EQ), the ability to assign the master volume control, a gain-reduction meter, device versioning, a tap-tempo function for scene switching, scene bypass behaviour and an IR load block.

You can find the full listing of the update and its features on the manufacturer’s page here.

1.4.0 Cortex Mobile Update
Cortex Mobile 1.4.0 is now available on the App Store and Google Play. The new version shows additional information when a preset is displayed, such as the devices used and the configured scenes.

The following features were added:

  • Preset metadata: You can now see a list of devices used in a preset, including the official manufacturer names of the models.
  • Preset scenes: You can now view the scenes configured for a preset and switch between them to visualise the bypass status of each device.
The following features were changed:
  • You can now edit or delete your uploaded presets or captures from your profile.
  • Several small UI and backend changes were made.
  • The "Preset Devices" and "Scenes" buttons are shown below the preset description.
  • The "Preset Devices" page lists all devices used in the preset and, where available, displays the manufacturer and product name.
  • On the "Scenes" page, the dropdown menu or the footswitches can be used to display the name of each configured scene in the preset as well as the bypass status of the devices used. In a future version it will be possible to interact with the devices to view parameter settings and more.

1.3.0 CorOS Update: New Looper Feature
With the release of the update CorOS 1.3.0 (for all release information click the manufacturer's link). In 2022 the Quad Cortex gained a looper function. The recording time is up to four minutes and 44 seconds. For maximum creativity the looper can be freely positioned on the grid!

Benefit from the steadily growing selection of guitar and bass algorithms

More than 50 amps, effects and IRs are already available!

Product information "Neural DSP Quad Cortex"

They created a monster!!!! Rarely has a modeller caused such a frenzy at the NAMM Show as the Neural DSP Quad Cortex. The compact floor unit is packed with the finest high-tech. At the heart of the Neural DSP is a super-fast 2 Ghz SHARC Quad Core processor - a real statement! The Neural DSP is operated via a 7" touchscreen - the footswitches can also be used as real-time controllers. On board are 50 first-class amp modellings, 70 effect modellings and no less than 1000!!!! IR cab sims. External IRs can be integrated very easily. But the absolute hit is the Neural Capture feature - existing equipment can be profiled and digitally modelled just like with the previous top dogs Kemper and AxeFX. The whole thing is housed in a very sturdy metal casing, which can easily withstand a knock or two (demonstrated impressively at NAMM when a sturdily built 130 kg employee jumped onto the device with a colleague on his shoulder! ). In addition to the usual MIDI and USB interfaces, a WIFI interface is also included, allowing all functions to be controlled remotely via smartphone.
