Neural DSP CorOS 4.1.0 Just Dropped and It's Absolutely Massive

What Makes CorOS 4.1.0 So Big?

Let's cut to the chase. Neural DSP has been on an absolute tear with the Quad Cortex platform, and CorOS 4.1.0 is the update that ties it all together. We're talking five new plugin packs coming to hardware, eight brand new virtual devices for every single user, over 2,000 factory device presets, and workflow improvements that'll make you wonder how you ever lived without them.

If you're running a Quad Cortex or Quad Cortex mini, stop what you're doing and update. Seriously. This one's worth it.

John Mayer on Your Pedalboard (Sort Of)

The headline feature that's going to get the most attention? Archetype: John Mayer X is now fully compatible with the Quad Cortex hardware. That means if you own the plugin, you can load every single device from it directly onto your unit. We're talking the Tealbreaker amp, the Headroom Hero, the Signature 83, the Smooth Operator, the Millipede Delay, the Dream Delay... all of it. Right there on your board.

And it's not just Mayer. CorOS 4.1.0 also brings Archetype: Petrucci X, Archetype: Misha Mansoor X, Archetype: Rabea X, and Archetype: Tim Henson X to the hardware. That's over 70 additional amps, cabs, and effects that you can now mix and match freely with native CorOS devices and NeuralDSP captures. Let that sink in for a second.

This also means Neural DSP has completed Plugin Compatibility for every currently available X-updated plugin. If you've been holding off on buying plugins because you weren't sure they'd work on your hardware, that excuse is officially dead.

Eight New Virtual Devices (For Everyone)

Here's where things get really interesting. CorOS 4.1.0 includes eight brand new virtual devices, and they're available to ALL Quad Cortex and Quad Cortex mini users. You don't need to own any plugins. They just show up when you update. Free.

The standout is the Multivoicer, which lets you add up to four pitch-shifted voices to your signal for layered harmonies and arpeggios. It originally debuted in Archetype: Tim Henson X, and now everybody gets it. If you've ever wanted to sound like you have an invisible second guitarist who plays exactly what you need, exactly when you need it, this is your new favorite toy.

Then there's Glitch, a granular delay engine from the Misha Mansoor plugin that chops your signal into repeating patterns. It can go from subtle textural movement to completely unhinged, machine-like destruction. It's not for the faint of heart, and it's awesome.

The Ring Modulator adds metallic, bell-like textures. The Arpeggio Delay lets each repeat have its own pitch and stereo position (hello, ambient players). The Crystal Delay creates bright, shimmering repeats that sit above your signal. And the Vintage Digital reverb, based on the BAM Space Generator by OTO Machines, nails that unmistakable character of old-school digital reverb processors, complete with a Freeze function for sustaining ambient textures.

Rounding things out, the Douglas Shining Comp (based on the Darkglass Hyper Luminal) is a studio-grade compressor, and the Plugin Parametric-4 EQ gives you precise four-band shaping with high-pass and low-pass filters.

If you're running NeuralDSP captures on your Quad Cortex, these new devices give you a ton of new options for shaping your tone before or after the capture block. Stack the Multivoicer into one of Six String Lab's amp captures for some seriously creative sounds.

Device Presets: The Workflow Feature You Didn't Know You Needed

This might be the sleeper hit of the whole update. Device Presets let you save the settings of an individual virtual device and recall them in any rig. That means you can dial in your perfect overdrive settings once, save them as a Device Preset, and drop that exact configuration into every preset you build from now on. No more rebuilding from scratch. No more copying and pasting between presets.

Neural DSP included over 2,000 Factory Device Presets to get you started. Two. Thousand. That's a massive library of ready-made starting points for every device in the system. And you can save up to 32 of your own User Device Presets per device, rename them, set defaults, and manage them however you want.

The Device Preset system also extends to I/O Settings and Global EQ, which is a godsend if you switch between different rigs for recording, rehearsal, and live shows. Save a configuration for each scenario and swap between them instantly instead of tweaking every parameter by hand.

Dual Footswitch Assignments

This one's for the live players. You can now assign a device's secondary function to a separate footswitch in Stomp Mode, which means you can control it independently from the device's bypass state. The example Neural DSP gives is perfect: put the Vintage Digital reverb's bypass on one footswitch and its Freeze function on another. Now you can sustain a chord with Freeze while independently switching the reverb on or off. That's the kind of performance flexibility that makes a real difference on stage.

Why This Matters for the Capture Ecosystem

Here's the thing that might not be obvious at first glance. Every one of these new devices, presets, and workflow improvements makes the Quad Cortex a better platform for running amp captures. The whole point of a great capture is that it nails the amp's core tone, but you still need great effects, great routing, and a great workflow around it to actually use it in a musical context.

That's exactly what CorOS 4.1.0 delivers. You can now pair your favorite NeuralDSP captures with plugin-grade effects, save your favorite signal chain configurations as Device Presets, and switch between setups without any hassle. If you've been building rigs with Six String Lab amp captures, this update just made your life a whole lot easier.

And if you're running captures on other platforms too, don't sleep on what's happening across the board. Kemper profiles got a massive boost with Profiling 2.0 earlier this year. Tonex captures are sounding better than ever with TONEX 2.0. NAM captures keep pushing the boundaries with open-source innovation. And HeadRush clones opened up to NAM support with their 5.1 update. It's genuinely the best time to be a digital guitar player.

Should You Update?

Yes. Absolutely yes. Even if you don't own any of the new plugins, the eight free virtual devices and the Device Presets system alone make this a must-install update. If you DO own plugins, this is the update that finally puts your entire Neural DSP ecosystem in one place on your hardware.

The Quad Cortex has always been a beast of a platform. CorOS 4.1.0 just gave it a serious upgrade in both capability and usability, and it didn't cost you a dime.

Level Up Your Quad Cortex Rig

Now that your Quad Cortex has all these shiny new toys, it needs some killer amp tones to go with them. Six String Lab has an ever-growing library of NeuralDSP captures that are dialed in for everything from glassy cleans to face-melting high gain. We've also got you covered on Kemper profiles, Tonex captures, NAM captures, and HeadRush clones.

Want to hear the difference before you commit? Grab a free pack and take them for a spin. Your updated Quad Cortex (with all those new Device Presets and effects) is the perfect playground to see what Six String Lab captures can do.
