Multi-touch Guitar and Bass Modeler with Capture Technology
The Quad Cortex floor processor from Neural DSP fuses high-precision studio guitar and bass tones with real-world gigging flexibility. This slim, self-contained floor processor is powered by Quad-Core SHARC DSP and Neural’s proven sound-modeling technology to bring today’s players the ultimate in grab-and-go session accessibility. Inside, more than 50 amps, 1,000 cabs, and 70 stomps serve as building blocks for crafting your favorite rigs, along with a built-in performance looper. Download presets from the cloud for instant genre/artist inspiration — no computer required — or use Quad Cortex’s Neural Capture to bring your favorite studio tones on the road with you. The Quad Cortex’s elegant layout is driven by a 7-inch full-color touchscreen and 11 rotary footswitches that twist and stomp to bridge hands-on amp tweaking and navigation with fuss-free foot control. Quad Cortex also gives you configurable inputs and outputs, which can be saved independently for each of its two user presets, along with MIDI and audio delivery over USB for producer-grade plug-and-play recorded tones. Believe it or not, Quad Cortex packs enough horsepower to serve multiple amp chains and even multiple players at once. So, whether you’re touring or tracking, both you and a bandmate can leave your amps at home when you’ve got the Neural DSP Quad Cortex in tow. Factor in firmware updates and user backups over Wi-Fi (again, no laptop required), unlimited set lists, and three modes of operation to line up tones to go, and it’s hard to overstate how dramatic an impact the Neural DSP Quad Cortex floor processor can have on your performance life.

Neural Capture digitizes your favorite amps, stomps, and cabs
Already have the world’s best amps waiting for you at home? Digitize them and take them on the road using Neural DSP’s powerful Neural Capture feature. Unlike traditional capture models, Neural Capture uses machine learning to replicate the sophisticated interaction between amp, cab, pedal, and player. Sag, saturation, breakup, compression — it’s all carefully preserved from the sound source straight into the Quad Cortex for instant recall. Neural Capture’s perception is based on the human ear, not on physics models, making it one of the most natural-sounding capture devices ever built.
Capture complete rigs or component parts
Neural Capture digitizes your favorite real-world amps, cabs, and pedals down to the building-block level. Let’s say you’ve got a JCM Hot Mod you just can’t gig without or a particularly smooth-sounding TS pedal you want to front-end other amps with. The Quad Cortex lets you capture the entire rig or save just the amp or pedal as blocks, which can then be used to build signal chains the same as any device from Neural’s device list.
XLR mic preamps with 48-volt phantom power
You’re not limited to just ’57s when capturing amps from your Neural DSP Quad Cortex. Mic preamps with XLR combo inputs and onboard 48-volt phantom power mean you can really experiment with mic choice and placement.
Preloaded with tons of great amps — with plenty more to come
Neural Capture isn’t the only way you can get your hands on fire-breathing modern stacks and high-class vintage combos using the Quad Cortex. From the squeakiest Cory Wong cleans to the grindiest Tosin Abasi gains, the Quad Cortex comes loaded for bear straight out of the gate. Here’s just a taste of what you get:

Get Neural DSP plug-in tones to go!
Here’s good news for Neural DSP plug-in lovers: the Quad Cortex lets you take your favorite desktop tones on the go via Neural's adapted Cortex-compatible interfaces of your purchased plug-in suites. Just log in to your Neural DSP account directly on the Quad Cortex, and bask in those Archetype and Parallax amp and pedal tones.
From NDSP's Quad Cortex FAQs:
Q: If I have bought Neural DSP plug-ins, can I get them on QC?
A: We will send a free plug-in update in a Cortex compatible format to everyone who owns our plug-ins, so the modules in them can be loaded onto the device.
Q: Can I load my Neural DSP plug-in presets on QC?
A: We are working on it!
7-inch multi-touch screen
A bright, responsive, full-color 7-inch touchscreen makes the Neural DSP Quad Cortex a breeze to navigate and a ton of fun to explore. Accessing settings and blocks is similar to using your mobile device: swipe up to show presets, swipe down to reveal amp parameters, touch and drag blocks to remove and reorder them in the chain, etc. Paired with the hands-on rotary switches, the Quad Cortex ensures you never get lost when you’re cruising for tones.
11 dual-function rotary footswitches
In addition to its snappy touchscreen interface, the Quad Cortex gives you a half score of stainless steel 2-in-1 rotary footswitches. These dual-purpose footswitch encoders put an entire amp-face of controls at your fingers all at once. The encoders twist like real knobs in your hands, and the switches stomp every bit as quickly and reliably as traditional footswitches. This not only saves space on the Quad Cortex — it also safeguards you from accidentally stepping on any fragile knobs in the heat of a performance.
“When you have both knobs and footswitches, you need to have enough clearance between them, so you don’t stomp on the knobs and break them. With the Quad Cortex, you not only save room, you’re actually shielding the weakest part [knobs] with the strongest part [footswitches]. The footswitch itself isn’t any less reliable, but the knob becomes as reliable as the switch. So you end up with a knob that doesn’t break.” — Doug Castro, Neural DSP/Darkglass Electronics
Bulletproof aluminum construction
The Neural DSP Quad Cortex comes in a rugged tour-grade anodized aluminum chassis for lasting looks and protection you can count on. This aluminum housing features laser-engraved graphics that, unlike printed graphics and stickers, won’t fade with time or leave behind any sticky residue.
1.8mm glass display shield
Heavy foot? The touchscreen of your Quad Cortex is shielded by 1.8mm of high-strength protective glass. This means peace of mind when you’re stomping away onstage or rushing to pack up after a show.
The Quad Cortex is one piece of gear that won’t leave you high and dry at the gig. Not only do you get a head-scratching amount of inputs and outputs with long-lasting Neutrik connectors, but you can even customize routing on a patch-by-patch basis. Here’s what's included:
- Dual combo inputs: combination TS/TRS/XLR inputs with variable impedances, built-in microphone preamps, phantom power, and level controls
- Dual effects loops: integrate mono/stereo outboard stomps into your Dual Cortex rigs, also supports 4CM (4-cable method) amp connections
- 1/4-inch output jacks: two mono balanced (TRS) output jacks, optimized for sound quality and noise
- XLR output jacks: two mono balanced XLR output jacks
- Headphone output: ideal for quiet practicing
- MIDI in and out/thru: automate switching and control every parameter in the Quad Cortex over MIDI
- Dual expression inputs: expression pedals can be assigned to control wah, volume, and pitch shifts
Built-in Performance Looper
Loopers have become a mainstay of modern music. Quad Cortex gives you access to this powerful creative tool with a built-in looper that boasts up to 4 minutes and 44 seconds of record time. The looper block can be placed anywhere on the grid for ultimate flexibility. In performance mode, you can control the looper with the footswitches, while parameter mode gives you total control over altering the looper's settings. Not only that, a handy quantize feature ensures your loop plays in sync with the Quad Cortex or external MIDI clock.
2GHz Quad-Core SHARC DSP
When Neural DSP refers to its Quad Cortex floorboard as the most powerful floor modeler on the planet, it’s thanks in part to the cutting-edge Quad-Core SHARC architecture contained inside. These SHARC chips pack a dedicated 2GHz of processing power to handle complex signal chains and shave latency down to imperceptible levels. Want to run four amplifier chains at once? How about stereo reverbs and a plethora of other effects simultaneously? The Neural DSP Quad Cortex won’t even break a sweat.
Supports multiple amps — or guitarists — at once!
Quad tracking — recording the same part four times and stacking the tracks — has become a common practice for capturing high-gain music. The Quad Cortex lets you approximate this practice in the live environment by giving you four independent signal paths complete with amps, stomps, cabs, and effects. Whether you’re cascading a single part into different flavors of amp saturation or building the ultimate virtual wet-dry rig to end all wet-dry rigs, it’s now possible from a single floorboard. Combine this with the Quad Cortex’s assignable inputs, and you can even share your Neural DSP guitar and bass tones with a bandmate to conserve space on the road. Now that’s cool!
Audio and MIDI over USB
You can capture stereo rigs straight into a recording session using the Quad Cortex’s low-latency USB connection. No additional interface is required, and the USB playback headphone feed offers several options, including none, USB 1/2, USB 3/4, or both via the I/O settings screen, letting you choose how you listen when using the Quad Cortex as an audio interface. Cirrus Logic codecs secure your place in the front of a mix. You can also access MIDI control over USB for deeper dives.
Built-in Wi-Fi module
Onboard Wi-Fi allows the Quad Cortex to communicate with phones and cloud servers wirelessly. Here’s what that means for your browsing and backup life:
Access new sounds wirelessly
Hungry for fresh tones away from home? The Neural CNS Mobile app lets you download and share presets wirelessly from your smartphone. Whether you’re after a particular amp, stomp, or artist preset, you can beam it straight to your Quad Cortex in real time for instant playback.
Update firmware from the cloud
Another benefit to the Quad Cortex’s Wi-Fi module is over-the-air firmware updates. Now you don’t even need to connect to a computer to ensure your operating system and tone database stay up to date.
Back up tones on the go
Find a new patch you can’t live without? Back up your Quad Cortex instantly over Wi-Fi and ensure it makes it home. There are no cables to plug in or laptops to track down.
10 set lists, 256 presets per set list
The Neural DSP Quad Cortex lets you organize your user presets into 10 set lists with 256 presets per set list for 2560 total presets. Now you can organize by band, project, genre, or date, allowing you to step through patches sequentially without stopping the flow of creativity. Searchable user tags (“djent,”“SRV,” etc.) help you quickly locate the tones you’re jonesing for — no more browsing and auditioning to locate that special rig.
Three modes of operation
A tap of the Active Mode soft button or a press of the two bottom-right footswitches cycles the Quad Cortex’s three operation modes. Modes let you get the most out of your Quad Cortex’s footswitch and patch customization.
- Stomp Mode: transforms the Quad Cortex into an elegant analog-styled pedalboard. Here you can activate or disable any block in a rig just by assigning it to a dedicated switch and tapping.
- Scene Mode: activate multiple blocks (overdrive and boost; reverb and delay) in a rig at once. Each preset has eight scenes recallable from switches A–H.
- Preset Mode: keeps your eight favorite rigs accessible via switches. This mode is great for players who want their clean, lead, and rhythm tones neatly lined up for quick access.
Dedicated tuner/tap switch
Need to tune up before a set or tighten up a rhythmic delay? A dedicated footswitch at the bottom-right corner of the Quad Cortex ensures you never lose your place. Just hold to tune or tap in time to tempo coordinate. The ultra-fine resolution tuner displays values in cents. Plus, you have the option to engage or disengage the tap tempo LED via the tap tempo screen.

What is a Sales Engineer?
The QC may bot be a fit for everyone, but for my situation (wood shedding, writing, composing, songwriting, recording, and playing guitar, bass and acoustic music), its what works better than expected. After carving out over 100 presets to build custom libraries, patches, and scenes for very workable quick recalls was easy. Routing options galore make for perfect injection other gadgets, stereo combinations, and more. The small footprint and simple patch building process flow, combined with cloud capture sharing of IR's and patches makes for building sounds simple. Found a few things like MIDI over USB to enable using Quantiloop, a 4 track looper for laying down ideas on the fly. Noting slack with the latest QC update's looper if one track looping is all you need, it beats others. Tough screen and rotary are great, I will wait for the UI app that will likely close the gap on Helix for desktop control. Only negative, and actually - its getting better; the effects. Quality & quantity is there and getting better. The first firmware was shy a few things for me and I paired it up with an HX Effects in the QC's effects loop, allowing placement of many variations of effects, anywhere in signal path, in stereo too. That combined with a couple expression pedals, one for the QC's 2 exp ports, 1 for the HX Effects 3 exp ports, both with break-out switches to control individually or at the same time, and an Airstep for the Quantilooper app (useful for many things actually), all direct- mounted to a Temple Audio board. Couldn't be happier. Thanks Sweetwater.
The intuitive interface and touchscreen makes tone chasing easier then ever before, not to mention how convenient the WiFi connectivity is to have. The tones out of this little box are INSANE. Even the stock presets are useable in a live or mix setting. I feature that took me by surprise was the pedal capture. Having the chance to try a Fortin 33 and other overdrives was a lot more fun than I anticipated.
I would love to see additional amp models and effects added to the quad cortex but I know that in due time the appropriate updates will make this product an absolute monster, ESPECIALLY once the plug-in integration takes place.
10/10 would recommend.
Unfortunately, I had gigs coming up where I fell back on my Rockerverb and vast array of pedals and footswitches to play gigs this summer as I ran out of time to perfect the Quad Cortex...so I boxed it up and sat on my shelf for a couple months while I lugged a metric ton of gear around to each show. I'd look at it every once in a while but I was uninspired, almost convinced a few times to just sell it and not hold out.
Fast forward to last weekend...I had just did a gig with my OWN tried and true PA, and I was not satisfied with the sound of my rig that I know and love, mostly due to not being able to juice my amp without overpowering the room...setting out on the journey again, I cracked open the Quad Cortex again, factory restored and updated it, and did a re-capture (dry) of my Rockerverb, and I fell in love all over again. Not sure what if anything changed, but it felt like night and day from my prior experience...but then I ran into the same issue of how to create a "footswitchable" neural capture (or amp block in general) and I just...couldn't do it...it doesn't exist. I'd have to swap between scene and stomp mode and it was just heading into dangerous territory for a live setting and was reliving the frustration all over again. I almost put it back in the box...
Then I got a lightbulb moment: what about MIDI??? I settled on a Morningstar MC6 fully programmable MIDI controller and got to work fine-tuning my rig. Not only was I able to set up the QC to create two "Scenes" that would switch between two amp captures *while at the same time* staying in "Stomp" mode on the QC, I was now able to perfectly program banks onto the MIDI controller where I could switch between gig and flow view, hold the same switch down and go to the preset that I need along with the default mode of the QC ("Stomp" or "scene", depending on song) and name certain blocks generically (like "Delay" and "Dist" instead of the names that) on the MIDI controller. I spent about 8 hours putting in the work and then making sure I could play songs all the way through just using the MIDI controller and occasionally a stomp or two on the QC depending on the moment. Then I routed the pre-cab sim'd signal into a power amp into my cab and I absolutely could NOT tell the difference between the QC and the real deal. Then finally, I put it through studio monitors and thusly...I finally achieved what I set out to do since the original purchase - pack the tube amps and some of my outboard stompboxes away and go fully digital for the first time since I picked up guitar in 2001. I still have some pedals I can't let go of or get absorbed into the QC...but the modeler is now doing most of the work.
I re-wired my pedalboard and brought it to practice the other day, where I have our own PA and monitoring system set up. I purposefully left my tube amps at home. This was it...if it didn't pass the test through a professional PA, I was probably going to put it up for sale. I plugged the XLR out to where a mic would normally go in front of a cab and my drummer and we let a song rip...wow...just, wow...not only was I grinning like an idiot, but in some respects, the sound was even more clear than a mic'd cab, especially since I wasn't battling resonance and feedback. The saturated tone was there even at lower volumes and it just sang in a way that I never thought possible. It sounds great with ALL of my guitars - Strat, Les Paul with P90s, SG with Seymours, Standard Tele...with some very minor adjustments, I can get the perfect sound out of every guitar now.
So after months of hemming and hawing over this thing, I finally obtained what *I* needed out of the Quad Cortex and I can roll up to a gig with just my pedalboard if I really needed to now, especially in venues with a good PA. With my setup...if the QC is the heart and soul of the amp/effects, the MIDI controller is the brain which is why it's front and center in my board. You will feel like a wizard after you figure out what works for you!
Keep in mind that this is my first modeler.
-Time flies by trying Presets and mixing matching Captures
-I'm personally a huge fan of not having Captures behind paywalls
-get to try ludicrously expensive and rare amps (via captures)
-customizable IR's that sound quite good (may take a second to dial in)
-intuitive Operating System
-easy to use App
-I find the Captures of Pedals lack flavor/essence
-lack of effects and pedals
-some cabs seem to have more TLC than others when changing mics/positions
-trouble picking up Wi-Fi
-over promised possibilities?
