Quad Cortex
Neural captures meet powerful modeling in a pedalboard-sized powerhouse.
About the Quad Cortex family
Quad Cortex blends Neural Capture (deep-learning amp profiles) with traditional modeling and a flexible four-grid routing canvas. Recipes here use the modeling library by default; capture-based variants are flagged where the original tone is best matched by a community capture.
Models in this family
- Quad CortexThe full unit — 8 blocks per grid, 4 grids
- Nano CortexCapture-focused stompbox, smaller grid
Patch conventions on Fader & Knob
- Recipes load as .qcs scenes — drag onto the Cortex Cloud or sideload via USB
- Captures referenced by a public Cortex Cloud handle when relevant
- Stereo grids used wherever the original tone is wet/dry/wet — labelled in the recipe notes
Why Quad Cortex players use Fader & Knob
Block names you can search
Every recipe lists the exact Quad Cortex block names — the same strings that show up in the editor or your unit's display. No guessing which model matches what.
Parameters in your units
Settings are translated to your platform's actual ranges — not generic 0–10 marks. dB is dB. Hz is Hz. Time is ms.
Snapshots & routing included
Where the original tone uses snapshot switching, parallel routing, or a specific footswitch assignment, we say so. You shouldn't have to reverse-engineer it.

Neural captures and amp models work differently. Here's when each one gives you better tone, and when it doesn't matter.
