Neural DSP Quad Cortex Mini

Quad Cortex mini delivers the full Quad Cortex experience in the most compact, usable format we’ve ever built, with no compromises.

It brings the same processing power, audio quality, Neural Capture technology, and 7” touchscreen experience as Quad Cortex, while taking up significantly less space. Built around an unprecedented level of processing power for its size and price, Quad Cortex mini delivers world-class sound that’s easy to dial in, with a huge range of tones and devices ready to explore.

Quad Cortex mini runs the same CorOS software and integrates fully with the Quad Cortex ecosystem. Presets, full backups, and complete workflows move seamlessly between devices, so everything works exactly as expected with nothing to rebuild.

The result is a powerful and versatile platform that removes the traditional trade-off between size and capability, delivering uncompromised sound and deep creative flexibility in a more portable, rack-friendly, and desk-friendly form.

Designed to slot straight into the way you already work

Quad Cortex mini is designed to slot straight into the way you already work. Whether you’re running a simple guitar rig, building a stereo effects setup, or integrating pedals, amps, microphones, and MIDI, everything you need is right here.

Interaction is centered around the combination of the 7” multi-touch display and four stainless steel rotary footswitches. These function both as switches and as dials for adjusting parameters, delivering the same responsive and tactile feel as Quad Cortex. This provides confident control under your feet and at your fingertips, both on stage and in the studio.

A versatile combo jack input allows you to connect either an instrument or a microphone, with phantom power available when needed. This input also serves as the Neural Capture input, making it easy to capture an amp in the studio, run vocals live, or track a quick demo at your desk.

Around the back, Quad Cortex mini offers balanced outputs for front-of-house and studio monitors, stereo effects loops, expression control, headphone monitoring, and comprehensive MIDI connectivity. The I/O is designed to adapt to your setup and enhance it, whether you’re building a compact rig or a more complex system.

Quad Cortex mini introduces a locking power connector to ensure reliable operation in live environments. Once locked in place, power stays secure, so you can focus on playing.

USB-C connectivity allows Quad Cortex mini to function as a fully featured audio interface, making it ready for live performance, home recording, and compact hybrid rigs right away.
 

Workflow and control systems

Despite its compact format, Quad Cortex mini offers a powerful and natural control experience.

At the core of this is the Focus system. When a block is selected, the rotary footswitches become dedicated controls for browsing models and adjusting parameters. This allows sounds to be dialed in by ear using physical controls, without needing to stare at the screen, making the experience quick, intuitive, and immediately familiar.

Pages add another layer of control without increasing the hardware footprint. Page 1 provides the main footswitch assignments, while holding a footswitch reveals Page 2 with an additional set of controls. This makes it possible to access more functionality under your feet while ensuring existing Quad Cortex presets behave exactly as expected.

Quad Cortex mini supports Preset, Scene, Stomp, and Hybrid modes. Preset mode is ideal for switching between completely different sounds, such as moving from one song to the next. Scene mode allows changes within a single preset, making it easy to move between different parts of a song. Stomp mode provides direct, hands-on control over individual effects, just like a traditional pedalboard. Hybrid mode lets you assign different Modes to each horizontal row of footswitches within the same preset.

For live performance, Gig View presents a high-contrast, performance-ready layout with large text and clear visual feedback. Opposite Page Preview allows you to see assignments from the other Page at a glance, so you’re never guessing mid-song.

Fast Mute provides instant silence when needed. A quick double-tap of the volume control immediately mutes the signal.
 

CorOS 4.0.0

Quad Cortex mini launches alongside CorOS 4.0. This update adds full support for Quad Cortex mini and introduces new devices that expand the creative possibilities of the platform.

New additions include Nordic Concert Hall, a large, open reverb inspired by classic concert hall algorithms and designed for spacious, cinematic sounds. Blossom offers a swelling reverb character that builds after the initial note, making it ideal for expressive playing and volume swells. Studio Plate 70 is based on classic studio plate reverbs, delivering a smooth and musical decay that sits naturally in a mix.

CorOS 4.0 also introduces Phase Doctor, a utility designed to resolve phase issues in stereo rigs and multi-amp setups, providing precise control when signals do not align as expected.
 

Cortex ecosystem

Quad Cortex mini integrates fully with the Quad Cortex ecosystem. Presets and full backups can be moved freely between Quad Cortex mini and Quad Cortex, with no changes required to existing workflows.

This makes it easy to share sounds across devices, maintain consistent rigs, or deploy multiple units for backup, redundant, or multi-instrument setups without rebuilding or reconfiguring anything.
