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.

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. Pro unlocks Perform mode, saving and switching sandwiches, the looper, MIDI control: $2.99/year or $8.99 once, forever. WHAT YOU NEED Requires an audio interface to plug in (USB-C recommended — e.g. iRig USB). Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
