---- Launch offer — introductory pricing for a limited time. The price goes up after launch week: now is the moment to patch in --- VisualSound is a modular instrument where sound and image are made of the same material. One canvas, one cable language: patch an oscillator into a filter, then patch the same signal into light, liquid and geometry. Nothing is a visualizer bolted on top — the picture IS the patch. ONE CANVAS, FIVE REALMS More than 140 modules across sound, control, visuals, geometry and code. Drag a cable and anything can play anything: an envelope strikes a fluid simulation, a sequencer bends a shader, a camera feed becomes an oscillator. INSTRUMENTS WITH OPINIONS • VYPER — a snarling acid bassline machine with slides, accents and pattern morphing. • KINETIC — a step-sequenced drum machine built on lovingly recorded classic analog kits. • KEYS — a playable polyphonic keyboard panel; on Mac, your QWERTY becomes the keybed. • SEQ, LFO, ENV, granular engines, a looper, a tape-stop, reels you can scrub like vinyl. LIGHT AS SIGNAL GPU-native visuals: shaders, feedback, bloom, fluid dynamics, sculpted 3D geometry. Point the camera at the world and use it as a texture. OCULUS tracks your hands and face so you can play parameters by moving. WRITE YOUR OWN MODULES — OR JUST ASK GRAIN is VisualSound's per-sample DSP language: code your own audio and visual processors right on the canvas. Tap the wand, describe the effect in plain English — "a dark tape echo that wobbles" — and an AI running entirely ON YOUR DEVICE writes the code, compiles it, and tells you honestly when something isn't possible. No cloud, no account. It works in airplane mode. (The AI brain is a free one-time download.) BUILT TO PERFORM Eight scenes with beat-synced morphing, motion loops, MIDI learn on everything, a timeline that can bend the tempo itself. Record your performance — audio and video — straight out of the app. PLAYS WELL WITH YOUR STUDIO Runs as an AUv3 instrument inside your DAW, and HOSTS your AUv3 synths and effects inside the canvas. MIDI in and out. Background audio. Files in, stems out. YOUR IPHONE IS THE REMOTE Install VisualSound on iPhone and it becomes VS Remote: a wireless control surface for the instrument running on your iPad or Mac, over your local network. No setup, no cloud. ONE PURCHASE, EVERY SCREEN Buy once and VisualSound is yours on iPad, Mac and iPhone. Same patches, same engine — the Mac gets QWERTY keys and plugin hosting depth, the iPad gets ten fingers on glass. PRIVATE BY DESIGN No accounts, no analytics, no ads. Your patches, recordings and prompts never leave your device. Privacy policy: https://visualsound.app/privacy/ Open the app and you land on Welcome — a living patch, already playing, wired for you to pull apart. That's the whole philosophy: understanding by unscrewing. Sound and light, patched together.
