WRITE • PHRASES of 16 steps hold notes, chords, instrument, velocity and effects; they stack into CHAINS, and chains arrange into a twelve-channel SONG • Hold a cell and slide to set a note or a value — it plays as you go • Select, copy and paste cell by cell, transpose whole sections, and end a note exactly where you want with OFF • Every channel loops on its own and can run at its own tempo, locked to one clock • A hardware keyboard on iPad and Mac, a MIDI keyboard, or any Bluetooth game controller drives the whole tracker SOUND • Over 450 ready-made sounds sorted by what they are — drums, bass, keys, bells, plucked, strings, winds, voice, leads, pads, fx — each one a tap away from playing, all balanced to the same loudness. Save your own for any engine • DRUM KIT: ten drum slots in one instrument — eight built-in kits, or build your own from any sound or sample • Classic synths: pulse, saw, triangle, FM, noise, supersaw pad, sub, pluck, wavetable and the dual-oscillator MODX, plus DRUM, an analog drum voice • WOVEN, a macro-oscillator with 24 models and 96 classic DX7 patches; ROUND, a resonator for strings, bars and bells; MODAL for struck percussion • SAMPLER: record or import, chop at transients, stretch to the tempo, loop, reverse, round-robin • SPEECH sings your lyrics in English and Japanese; GRAIN turns any recording into clouds; DRONE, RESONATOR and TEXTURE build ambient beds • AUv3 hosting: play your instrument plug-ins and insert effect plug-ins on any channel SHAPE • 32 effects on any note: delays, reverbs up to thirty seconds, tempo-synced gate and autopan, retrigger, chorus, flanger, ring mod, wavefold, bitcrush, slides, vibrato, arps, FOGGY granular clouds and more • AUT automation morphs an instrument and its effect across the rows • RANDOM dice, tables for instant arpeggios, a groove editor per instrument, scale lock • A twelve-channel mixer with volume, pan, mute, solo and plug-in inserts PERFORM • LIVE MODE: launch phrases from six scenes on pads, quantized to the beat or the bar, and punch in delay and filters — or latch them CONNECT • MIDI in with step and live recording, MIDI out to hardware, MIDI clock and Ableton Link KEEP • Render to WAV (16 or 24 bit), stems and MIDI; share songs as files; your session autosaves • A lock-screen player with cover art in your theme • 28 themes — the studio look comes in dark and light and can follow your device — a theme editor, seven typefaces, hex numbers if you like • English and Japanese, and a demo song to start from Everything runs on your device.

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.
