Celestine Granular FX

Live-buffer granular AUv3

USD 11.99

iPad

No samples required. Celestine listens as you play and transforms your sound into shimmering clouds, orbiting textures, and evolving ambient beds. Introductory launch price for early users. $5.99 for the first two weeks. Regular price will be $9.99. Feed it vocals, guitar, synths, piano, drums, field recordings, or full mixes, and Celestine transforms the incoming sound into shimmering clouds, drifting harmonics, orbiting textures, rhythmic fragments, and evolving ambient beds. No samples to load. Celestine listens continuously through a rolling live buffer. Whatever you play becomes the source material. Incoming audio is broken into swarms of micro-grains that can be pitched, reversed, widened, scattered, synchronized, softened, distorted, and animated in real time. Insert it on a track, blend dry and wet, send multiple sounds into it, or perform it like an instrument. From delicate halos to chaotic scatter, Celestine is built to feel organic, musical, and expressive. Eight granular engines: Grain: classic granular textures Mosaic: pitch-shifted harmonic clusters Glide: bending, sliding grains Reverie: dreamy reverse washes Bloom: ghost-echo reflections Tide: amplitude wave undulations Stars: rhythmic anchor patterns Orbit: circular spatial movement Shape time, pitch, density, motion, tone, and space. Scrub through the live buffer by hand, or lock grain triggering to the host tempo for evolving patterns and rhythmic clouds. Built-in effects: Wavefolding distortion for rich harmonic color Bitcrush for subtle grit or digital destruction Lush reverb for spacious depth Magic multi-FX with seven tone-shaping algorithms Dry/wet blending for subtle enhancement or full transformation Celestine turns melodies into glowing pads, vocals into spectral choirs, guitars into frozen halos, drums into glittering glitches, and simple loops into evolving celestial motion. Ideal for ambient, cinematic, IDM, and sound design. Under the hood: Real-time live-buffer granular processing 8 distinct granular engines Up to 30 simultaneous grain voices Tempo-synced, bar-locked grain triggering Pitch, reverse, width, scatter, motion, and timing controls Wavefold, bitcrush, reverb, and Magic multi-FX Smooth, click-free DSP Celestine is an AUv3 audio effect and requires an AUv3-compatible host app. Made by ijo audio. Introductory launch price for early users. $5.99 for the first two weeks. Regular price will be $9.99.
