Patchsynth

Features
Read full description

Patchsynth is a Eurorack-style modular synthesizer for iPhone and iPad — and a place to actually learn how modular synthesis works, one patch cable at a time. Instead of a fixed synth engine with knobs, you build your own instrument by dragging cables between modules: oscillators into filters, envelopes into amplifiers, LFOs wobbling anything you point them at. If you've ever wanted to understand what a Eurorack rig actually does, this is the fastest way in. LEARN BY PATCHING, NOT BY READING 28 hands-on Lessons cover every module, from your first oscillator to full generative patches — some just explain, others build a real patch step-by-step in front of you as you tap "Next." No prior synthesis knowledge required. TRAIN YOUR EAR 15 Challenges hide a patch and play it for you — your job is to rebuild it by ear, with hints if you get stuck. A genuinely fun way to internalize how filters, envelopes, and modulation actually sound. 21 REAL MODULES Oscillator · Filter · VCA · ADSR Envelope · LFO · Noise · Delay · Reverb · Mixer · Sequencer · Arpeggiator · Clock · Attenuverter · Quantizer · Slew Limiter · Sample & Hold · Logic · Ring Modulator · Sampler · Keyboard · Output (with a live oscilloscope) Record your own sounds with the Sampler, or use the built-in factory drum kit. Quantize any CV to a musical scale. Chain multiple clocks for polyrhythms. It's a real modular rig, just without the cables costing $30 each. 70+ FACTORY PATCHES From simple bass and pad sounds to sprawling, 20+ module "flagship" patches — browse them, load them, take them apart to see how they're wired, then make them your own. PLAY IT WITH REAL GEAR Full MIDI support over Bluetooth or USB — plug in any MIDI keyboard or controller and play your patch's Keyboard module directly, no setup beyond pairing. BUILT FOR TOUCH, NOT PORTED FROM DESKTOP Every interaction — dragging cables, turning knobs, panning and zooming a big patch — is designed for a phone screen from the ground up. A dedicated Patch Bay view even gives you a spreadsheet-style matrix of every connection when patches get complex. Undo and redo everything. Save as many patches as you like. No ads, no in-app purchases, no internet connection required — just synthesis.

---- 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.
