Your AI guitar tone engineer. Describe any sound—artist, song, or vibe—and get a complete Quad Cortex preset in seconds.
Dialing in the perfect guitar tone takes years of expertise. Cortex ToneAI puts an AI audio engineer in your pocket.
Built exclusively for Neural DSP Quad Cortex players, Cortex ToneAI 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 ToneAI 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
• When connected
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 is saved to your personal library. Browse your collection, view the full signal chain, and send any preset to your Quad Cortex instantly.
BUILT FOR THE QUAD CORTEX
• Cortex ToneAI knows the entire Quad Cortex amp and effects library. 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 ToneAI is an independent app and is not affiliated with or endorsed by Neural DSP Technologies.
