## What is Cortex Studio?

Dialing in the perfect guitar tone takes years of expertise. Cortex Studio puts an AI audio engineer in your pocket.

Built exclusively for Neural DSP Quad Cortex players, Cortex Studio  turns a simple description into a complete, ready-to-build preset. Type "Slash GNR metal cranked through Marshall amps" or "David Gilmour Comfortably Numb solo" and the AI delivers every setting you need—instantly.

Describe any sound: an artist, a song, a decade, a genre, or just a vibe. Cortex Studio generates:
• The exact Quad Cortex amp model to use
• Gain, bass, mid, treble, presence, and master settings
• A full signal chain with every effect in the right order
• Cabinet model, mic type, and mic position

MIDI CONTROL
• Connect your Quad Cortex via USB and send Program Change messages directly from the app. Build your tone on the QC, save it to My Presets, and recall it with one tap—no menu diving, no footswitch gymnastics.

PRESET LIBRARY
• Every AI-generated preset can be saved to your personal library. Browse your collection, and recall the preset on your Quad Cortex instantly.

BUILT FOR THE QUAD CORTEX
• Cortex Studio knows the entire Quad Cortex amp and effects library available to view under devices. Every recommendation uses only models and effects available on your device—nothing hypothetical, nothing unachievable.

YOUR KEY, YOUR QUOTA
• 25 free AI requests included—no sign-up, no credit card. For unlimited use, connect your own free Google Gemini API key in seconds (aistudio.google.com, no credit card required). Your key stays private in your device's Keychain and is never shared.

PERFECT FOR
• Quad Cortex owners who want to find tones faster
• Players who know the sound in their head but not the settings
• Live performers who need quick, reliable preset recall via MIDI
• Studio players chasing specific artist or song tones

NOTE
• Cortex Studio is an independent app and is not affiliated with or endorsed by Neural DSP Technologies.

### 2/5 — Great concept but needs work

*2026-08-05*

App is able to get pretty close to most tone clues you give it but parameters that are given OFTEN do not align with the options for that model pedal/amp etc (amps that don’t have presence setting, compressors that don’t have sustain, cab terms, etc).  Would think this is an easy fix as it is very clear what options the preloaded efx in the QC have on them…just not sure why doesn’t match and can leave you with tone that is “off”

### 1/5 — Cortex studio disappointment

*2026-07-20*

I love the layout but the app is constantly makes parameter suggestions that aren’t available on the suggested devices. I.E. sustain and attack on a jewel compressor or suggesting a mid settings on a UD DLX 64 Vintage

## Version history (last 5 releases)

### 2.8 — 2026-08-27

Updated devices list

### 2.7 — 2026-08-26

Updated to the latest Gemini AI model for improved tone suggestions.

### 2.6 — 2026-08-20

Smarter Artist Tone Accuracy
The AI now identifies the exact, historically documented amp used on a recording — not just a stylistically similar substitute. Ask for "Hungry Like the Wolf" and you'll get the Roland JC-120 Andy Taylor actually played. Ask for AC/DC and you'll get the Marshall Plexi, not a generic British amp.

Better Cabinet Matching
Presets now automatically pair the historically correct cabinet to each amp — Marshall cabs with Marshall amps, Vox cabs with Vox amps, and so on — for more authentic tone out of the box.

Improved Preset Structure
The AI now accounts for the Quad Cortex's 4-scene layout and 8-block limit when building presets, keeping headroom for live scene switching and expression pedal assignments.

### 2.5 — 2026-04-18

API Key Compatibility Fix
- Google updated their Gemini API key format and new keys were being rejected at the entry screen. This has been fixed — all valid key formats are now accepted.

### 2.2 — 2026-03-23

Minor bug fixes tand UI improvements.
