ostinata lets you map the actual paths you take through music. ever gone from radiohead to aphex twin because kid a changed how you think about electronic music? from miles davis to j dilla because someone sampled a love supreme? ostinata turns those invisible threads into visual, shareable directed graphs. — how it works — create a journey by adding nodes — artists, albums, genres, emotions, or concepts. connect them with directed edges that show which discovery led to which. add reasoning text to explain the connection. the result is a map of your taste that others can explore, fork, and build on. — search & discover — search for artists and albums via musicbrainz, the open music encyclopedia. album nodes display cover art. long-press any node to open its musicbrainz page for deeper exploration. — fork & remix — see a journey that resonates? fork it. you get a copy of the entire graph — all nodes, edges, and reasoning — that you can extend, rearrange, or take in a completely different direction. — bounties — post discovery challenges for the community. set a topic like "find the link: kraftwerk to detroit techno," define seed nodes as starting points, and offer resonance as a reward. other users form guilds of five to tackle the challenge together. — your data, your cloud — everything syncs privately via icloud. we store nothing on our servers. your journeys, your data, your control. — design — black canvas. white lines. ibm plex mono. all lowercase. album art in grayscale. ostinata is built for people who care about how things look as much as how they sound. ostinata — discovery through human curation.

Pruina freezes sound. Tap once and Pruina captures the spectrum of whatever is playing, a chord, a vocal, a whole mix, and holds it as an endless, gently evolving drone that never decays. Then shape it into rising shimmer clouds, breathy air, crystalline bells, or a huge reverberant wash. Under the hood it runs a real spectral analysis of your audio and, the instant you freeze, takes a snapshot and resynthesizes it with slowly drifting phase. Instead of fading away, the sound sustains forever and breathes, like a pad you never have to hold down. THREE MODES, ONE ENGINE Freeze: tap to capture and hold the spectrum indefinitely. Smear: continuously blur the spectrum into a soft, washing texture. Shimmer: pitched, regenerating layers that rise endlessly. SHIMMER THAT RISES Choose an interval (octave, fifth, octave plus fifth, or two octaves) and turn up Regen to feed the shimmer back on itself, building infinite cascading clouds. BUILD CHORDS BY EAR Turn on Layer and every freeze adds to what is already held. Stack captures into evolving chords and pads, live, one tap at a time. SCULPT THE SOUND Blur: smear the spectrum across frequency to morph a pitched freeze into breath and air. Sparkle: gate down to the spectral peaks for glassy, bell-like tones. Warp: stretch the timbre. Motion: slow drift and breathing that keep a frozen pad alive. Tone: low cut, high cut, and tilt. SPACE A lush, modulated reverb (Reverb, Size, Damp) wraps everything in a wide, dimensional tail, from an intimate room to a cathedral that rings for minutes. Stereo Spread and Width open it up. 16 READY-TO-PLAY PRESETS Infinite Cathedral, Rising Aurora, Supermassive, Glass Bells, Crystalline, Frozen Choir, Ghost Vox, Vapor Trails, Nebula, Granular Dust, Shimmer Wash, Dark Matter, Sub Bloom, Slow Tide, Chord Builder, and Default. Browse them with the header arrows, tweak anything, and save your own. PLUGIN AND STANDALONE Full AUv3 audio effect for GarageBand, AUM, Logic, and any AUv3 host, with host presets, parameter automation, and reported latency so your project stays in sync. Runs on iPhone, iPad, and Mac. Standalone mode includes a built-in demo pad, live microphone input, and song import with export of the processed result.
