This Live Granular Processor lets you decompose audio into bits and pieces or lovely clouds. Dual Live Buffers Quantum Granulator is a powerful live granular processor designed for deep, hands-on sonic manipulation in real-time. Two independent recording buffers capture your signal and let you freeze, loop, or continuously record audio for instant transformation. Whether you’re sampling from the Main Input, Sidechain A, or Sidechain B, you’re in full control of what goes in — and what comes out. Musical Grain Engine Trigger grains freely in Hz or lock them to tempo for tight rhythmic effects. Adjust grain length, offset and density — from crisp stutters to blurred, cinematic clouds. Randomization adapts to your mode: in Hz it behaves like a geiger counter, adding sharp, bursty unpredictability; in BPM sync it becomes more spray-like, scattering grains around the beat for rhythmically coherent textures. Expressive Pitch Control Our easy-to-use scale picker lets you quantize grains to 30+ built-in musical scales, create your own, or let randomness take over. Play grains via MIDI to turn Quantum Granulator into an expressive granular instrument. Pitch shifting covers a broad ±24 semitone range and a separate fine control allows subtle adjustments within ±1 semitone, perfect for microtonal tuning or adding vibrato-like motion. Versatile Grain Shaping An intuitive 2D Envelope XY pad lets you sharpen or soften vertically, adjust attack and release horizontally. Control level, panning, and filtering to craft subtle movement or fully chaotic sound clusters. Shape the balance using the mix section — from subtle texture to complete granular obliteration. Granular Synthesis, Made Playable Quantum Granulator isn’t just a tool — it’s an instrument. Built for performers, producers, and sound explorers alike, it offers a deep but immediate interface into the world of granular synthesis, with every detail tuned for musicality and expression. Quantum Granulator is an AUv3 audio effect plugin compatible with Logic Pro, AUM, Cubasis, GarageBand and many more. A Desktop version is also available for Windows and macOS (VST3 / AU / AAX).
