Cortex Studio2.8 - App Store

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.

Version History Updated devices list 2.8 Aug 27 Updated to the latest Gemini AI model for improved tone suggestions. 2.7 Aug 26 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. 2.6 Aug 20 API Key Compatibility Fix
