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.

Groove Destroyer isn't a gate, stutter, or glitch effect. Instead of chopping your audio into predictable patterns, it continuously reinterprets the groove underneath your music. Rhythms shift, accents evolve, filters dance, and movement emerges that feels alive instead of programmed. At the heart of Groove Destroyer is an intelligent groove engine that generates evolving rhythmic events while preserving the underlying pulse. Resonant filters, animated movement, saturation, and controlled instability combine to produce textures ranging from subtle motion to complete rhythmic mayhem. Use it on drums, percussion, synths, guitars, loops, vocals, or entire mixes whenever you want movement that sounds organic rather than mechanical. Whether you're adding a little instability or pushing a beat to the edge of collapse, Groove Destroyer creates grooves that never play exactly the same way twice. Features Intelligent groove engine Host tempo synchronization Animated dual resonant filters Organic rhythmic mutation Stateful evolving movement Built-in saturation and glue Seven macro controls Factory presets from subtle to extreme Controls Destroy Controls the overall intensity of rhythmic destruction and filter movement. Swing Introduces evolving timing offsets and rhythmic feel. Density Controls how frequently the groove engine generates new rhythmic events. Scatter Adds unpredictability by introducing off-grid rhythmic movement and evolving filter behavior. Push Moves rhythmic events forward or backward to create urgency or hesitation. Glue Blends saturation and dynamic cohesion to keep evolving rhythms feeling musical. Mix Blends processed and dry signals. Ideal Uses Drum loops Electronic beats Percussion Synth sequences Basslines Vocals Guitar Parallel processing Entire mixes Sound design
