State-of-the-art floor modeller for guitar and bass

With 2 GHz of DSP performance from its quad-core SHARC processor and its integrated USB audio interface, full MIDI compatibility, 7" touchscreen display, and full array of inputs and outputs, the Neural DSP Quad Cortex is certainly one of the most powerful and best-sounding effects units out there for guitarists and bassists. Users can choose from over 50 amp models and 70 top-flight effects, as well as 1,000 impulse response (IR) cabinet simulations. The Neural Capture technology, through which the sound characteristics of any amplifier and any cabinet can be reproduced to an astonishing degree, represents a brand-new approach in the world of sound modelling. The Neural DSP Quad Cortex reproduces each setup exactly as the human ear perceives it and offers really natural-sounding amp simulations.

Clear and simple operation via touchscreen

The central 7" colour touchscreen display allows you to create unique patches in no time via drag-and-drop. In addition, the 11 sturdy metal switches also act as rotary controls and will allow any corrections to the sound to be made in a flash. The integrated Superior Modelling Technology makes a constantly growing number of algorithms with uncompromising sound quality possible, thus rendering additional equipment redundant. Nevertheless, the unit is also equipped with two effects loops that will allow you to integrate your favourite pedals into the setup. What is more, the Neural DSP Quad Cortex is equipped with a pair of balanced stereo outputs, two expression pedal inputs, a MIDI interface, and two combined XLR/6.3 mm (1/4”) jack inputs and thus provides immense flexibility. Finally, the 48 V phantom power option makes the stereo inputs perfect for vocals and acoustic instruments.

Three modes, setlists, and gig view

The Neural DSP Quad Cortex has three different modes that allow it to be adapted to any situation. In "Stomp Mode", the unit behaves like an analogue pedal board. "Scene Mode", on the other hand, controls any desired number of effect blocks within a rig, while "Preset Mode" allows direct access to up to eight virtual rigs. By creating so-called "setlists", the patches can be clearly organised and managed – each setlist can comprise up to 32 banks of eight presets each. This allows presets to be sorted by category, project, or album and recalled in seconds. Another practical feature is the Gig View function, which provides a full-screen view of the footswitches’ current function.

About Neural DSP

Founded in Finland in 2017, Neural DSP regards itself as a developer and provider of computer-based solutions for the music industry. Inspired by innovative technologies such as advanced algorithms and machine learning, Neural DSP Technologies initially developed software plug-ins. New products have been released at regular intervals, most of which faithfully reproduce legendary amps or, in collaboration with popular guitarists such as Plini and Tosin Abasi, exactly reproduce their characteristic sounds. The Quad Cortex, the first hardware product from the still-young company, was released in 2021 and, true to the company's credo, is intended to bring artists a new level of creative inspiration through technological innovations.

A veritable workstation

With its huge number of high-quality amp simulations, over 1,000 cabinet simulations, numerous effects, and intuitive touchscreen navigation, the Neural DSP Quad Cortex is undoubtedly aimed at professionals who will put it through its paces in the rehearsal room, in the studio, or on stage. Besides delivering authentic sounds, this board also has impressive connectivity and will handle pretty much any application. Furthermore, the unique "Neural Capture Technology" means that the sound and behaviour of any amplifier or rig can be replicated, permanently saved, and recalled at will, so that the capabilities of the Neural DSP Quad Cortex will keep on growing.

For the stage and the studio

Whether in the studio, in the rehearsal room, or on stage, the Neural DSP Quad Cortex will always be up to the challenge, whatever the context – and will always impress thanks to its sophisticated operating concept, unparalleled routing flexibility, and clever features such as the footswitches with integrated rotary control function. Although designed primarily for guitarists and bassists, the Quad Cortex can also be used for processing vocals, keyboards, and many other acoustic instruments thanks to its phantom-powered microphone inputs.

This is basically just a prototype... (and you can't direct monitor on Windows)
ligma fingaz 04.01.2022
Direct Monitoring feature still is unusable on Windows as of January 2022. I have tried every QC OS update/USB driver/windowsOS workaround on the PC of every bedroom producer I know and all with the same result. The entire signal gets bitcrushed when you record, fizzy unusable mush. Line-outs work just fine. Never had this issue occur on a Mac.

Side-note: I'm pretty disappointed that many teased features (such as being able to load Archetype plugins, having a desktop editor) have not been added and at this point never will be. I anticipate they'll put out a new unit with this feature in a few years and leave any early adopters in the dirt. This unit is rusting away, a waste of potential. The company's focus seems to have shifted almost entirely to their plug-in users. Not acceptable conduct at this price-point. I dare you Neural, prove me wrong in the next update

Lastly: flimsy unconditioned power supply, should come with something more reliable. USB 2.0 Type B is practically extinct why is it on this unit? Why doesn't the app have audio demos for user presets? Why is it so cluttered to navigate? Why is there so much latency switching presets?


Perfect form factor.

As soon as you open the box and take it out you feel the quality straight away. The Quad Cortex is simply lovely to hold and looks sleek and modern. The touch screen makes it look on par with an iPhone or Android device. The fact the stomps double as knobs make this super easy to use.

This ease of use is my favourite thing about the QC. My previous modeller was always hassle for dialling in tones, particularly heavy tones, and always sounded a bit plastic. When I enquired about it on the related forum people were recommending third-party IRs. The QC, on the other hand, works great out the box with no IRs needed as the ones supplied do the job.

If there's any downsides it still needs some features like a looper and desktop app, and some more models, but like all of these types of devices its an ever evolving platform and they're sure to come.

I think overall, though, this device has been a great purchase. I've spent far less time dialling in which means more time playing and simply having fun. If you are already familiar with the plugins and love that sound then this device is highly recommended for if/when you decide to start stepping out of the bedroom.


Great potential, but...

Sound-wise, I have no complaints. It sounds really good and it stands up to the more expensive competition. Capturing is better than the Kemper.

But what limits and bothers me a lot is the way the presets are managed. It's really unpolished at the moment. I don't understand why I can't save presets to my computer. The cloud solution is cool, but I want to have other options. Can't work with multiple items at once, in a batch. This is very annoying and tedious.

The second thing is the non-existent desktop editor. Since I work in a studio, I need new sounds every day. I'm really tired of having to leave my desk for every edit and deal with everything physically on the unit because I can't do it any other way.

I've had it for almost a year now and it has two big pluses: sound quality and ease of use.
It is so easy to move around the blocks and build complex rigs really fast. I'm usually runnig two guitar lines with a detuned line for a bass emulation all in a single preset and it can handle it with no issue.
As for the sound quality, it is what you can expect at this top price range. I've had other simmilar devices (Kemper) and it is simply undistinguishable regarding the captures/profiles.

As for the downsides, the preset exchange on the app is a bit messy, you cannot download and share single presets "offline" as you can with other similar devices. So far they have been quite consistent with the updates.

I'm still curious about the build quality. So far so good but have not had any gigs yet.
Would definietly recommend.
