Stacks - Granular Looper

Stacks - Granular Looper is a creative music app for granular synthesis, looping, and live sound design. Build textured layers, reshape samples in real time, and perform with expressive controls. Ideal for producers, beatmakers, and live performers seeking a fast, intuitive workflow for music production and sound design. Core features - Granular engine: slice audio into grains to time-stretch, pitch-shift, and re-sequence without losing groove - Multi-layer looping: overdub, stack layers, and keep everything tight with tempo sync - Real-time effects and modulation: sculpt tone with filters, delay, reverb, and automate key parameters for evolving textures Use cases - Live performance and improvisation with hands-on loop control - Sound design for ambient, glitch, and experimental textures - Fast sketching of ideas and exporting loops for your DAW

1. Install and open the app, then set your input and output levels and grant microphone access if you plan to record. 2. Create a new project, set tempo or choose free timing, then record a phrase or import a sample from your library. 3. Enable granular controls and adjust grain size, density, position, and pitch to reshape the sound in real time. 4. Loop and layer by overdubbing additional parts, using mute and solo to balance stacks, and keeping everything in sync. 5. Add effects and simple automation for movement, then save your project or export audio loops for further production or performance.
