THE APP FOR STRATUS® & NIMBUS® Control the most powerful guitar effects pedal and amp modeler on the market, both powered by AI. AI FX BUILDER — CREATE ANY EFFECT YOU CAN IMAGINE Just describe the sound you want: "Give me a dynamic tremolo/phaser that's more tremolo-y and slower when I play softly, but smoothly gets more phaser-y and faster as I dig in." The AI builds it. Not just a preset... a brand new algorithm. No other guitar gear on earth can do this, and it comes FREE with Stratus and Nimbus. --- NEURAL AMP MODELER — 300,000+ AMP & GEAR CAPTURES In partnership with TONE3000, get instant access to a massive community library of Neural Amp Modeler captures — real tube amps, cabs, and gear, modeled with stunning accuracy. Browse, load, and A/B between model variants right in the app, and share NAM-powered presets with anyone through Chaos Cloud. Need cabs too? Add Impulse Responses (IRs) as their own effect, also available from TONE3000 for free in the app. --- BRING YOUR OWN — UPLOAD YOUR CAPTURES & IRs Got your own amp captures or impulse responses? Upload your private NAM captures (.nam) and IRs (.wav) straight from the app and drop them onto your board like any other effect.

Tone Scope Lab
Read full descriptionHide full description
Tone Scope Lab is a real-time tuner and spectrum analysis tool designed for musicians who want to see pitch, not just read a number. At the center of Tone Scope Lab is its infinite circular pitch ruler, which provides a continuous visual view of pitch movement while you play. Real-time spectrum visualization lets you see the frequency components of your instrument’s sound, providing another visual perspective alongside the pitch ruler. The Transpose Ruler provides a quick visual reference for transposing instruments, helping you relate written and sounding pitches at a glance. Choose from three generations of analysis and display systems: • Gen-1 — a simple and direct tuning view • Gen-2 — enhanced analysis and visualization • Gen-3 — the latest generation, combining multiple stages of analysis for more focused pitch detection Tone Scope Lab also supports instrument presets. The built-in General preset provides flexible, all-purpose tuning, while additional instrument presets can be downloaded for more focused analysis ranges. Features: • Real-time pitch detection • Infinite circular pitch ruler • Real-time spectrum visualization • Transpose Ruler for transposing instruments • Frequency display • Three generations of analysis and display • Instrument presets • Downloadable additional presets • Adjustable spectrum display modes • Designed for instrument practice, tuning, and sound observation Tone Scope Lab is designed to make pitch behavior visible — from a simple tuning reference to a deeper view of how your instrument’s sound behaves.
