Cortex Studio vs NAM Sandwich

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.

Hi - I'm Evan, a mobile developer for over 10 years and a gigging guitarist for over 20. I created this app to be as simple to use as possible with all the features you could want to play live, or just jam by yourself at night before you go to bed (like I do). NAM Sandwich turns your iPhone or iPad into a complete, fully customizable Neural Amp Modeler rig! BUILD YOUR SANDWICH: Your tone is a stack of layers you arrange however you like: • Amp & pedal captures (NAM) - stack as many as your tone calls for • IR loader - drop in cab impulse responses and creative IRs • EQ - switchable 2-band or 3-band tone stack • Noise gate - reduce the hiss on those heavy tones • Delay - from slap-back to long modulating echoes • Reverb - plate and spring • Tremolo - customizable stereo/mono trem with lots of options • Flanger - classic jet engine swoosh and trippy swirling effects • Chorus - 3 modes modeled after classic effects • Phaser - 3 voicings modeled after the most iconic pedals • Wah/Auto-wah - In three voicings: Vintage, Modern, Wide • Pitch - drop tuning, transposing and detuning without touching your strings • Gain - low-cut, high-cut and level to tighten up or level out any capture • AUv3 - host third-party effects as layers Add, remove, and rearrange layers freely to build a rig that's truly yours. THOUSANDS OF TONES, A TAP AWAY Powered by TONE3000 — browse thousands of NAM captures and IRs from your own TONE3000 account, right inside the app, and hear one through your rig before you keep it. https://www.tone3000.com PERFORM-READY Create as many preset banks as you like (I call 'em menus), organize your sounds into favorites, set lists, tones, whatever your heart desires. LIVE LOOPER Lay down a loop and play over it. Record 4, 8, 12 or 16 bars at your tempo, or use free-style mode and stomp in and out like a looper pedal. Switch sounds on the fly when recording! Save the loops you want for good. MIDI CONTROL Connect a Bluetooth, USB, or network MIDI device (e.g. XSonic AIRSTEP) to control preset changes, tuner, tap tempo and more - hands-free. ON IPAD Your saved sandwiches sit beside the builder, so you can pick a rig on the left and tweak it on the right. Works in either orientation - handy on a music stand. JAM OVER YOUR MUSIC Pull up a song and play right along. Perfect for practice, songwriting, and the couch, tour bus, hotel room, or backstage. BUILT-IN TUNER A fast, accurate chromatic tuner is one tap away - no extra app, no pedal. Stay in tune wherever you play. AUV3 SUPPORT NAM Sandwich can be used as an AUv3 effect inside host applications (e.g. GarageBand) and can also host AUv3 effects as layers in a sandwich! FREE TO PLAY, PRO TO PERFORM Building your sandwich, playing through it, the tuner, and browsing and downloading captures are free, for as long as you like.
