Grainsmith Field vs HeadStack

Grainsmith Field is a granular instrument for iPad and iPhone. Load a sound or record one live, then pull it apart into grains. Stretch and scatter it until it stops sounding like the source, or pitch it and play it like an instrument. It shares its granular engine with our desktop Grainsmith plugin, but it's rebuilt for touch. Field is a single multitouch screen: four XY pads control paired parameters (Density and Size, Jitter and Spread, Pitch and Reverse, Cutoff and Resonance), and a Morph control sweeps several at once. THREE PLAYHEADS Run up to three independent grain streams from one sample at the same time. Each head has its own position, speed, pitch, level, pan, grain size, and spread. Grab a playhead line on the waveform to move it independently, or move them as a group. Double-tap to gather them. Set a second head a fifth or an octave away and the streams blend into a single granular texture. MODULATION Six modulation slots drive the controls: LFOs and Euclidean patterns with per-route depth, assigned by long-pressing a knob. The MOVE dial sets the Morph macro itself in motion, and each destination drifts on its own phase. Rates sync to tempo, in the app or from the host clock. RECORD AND MANGLE Capture audio from your hardware input and granulate it as it comes in, or loop a phrase and let the engine chew on it. Scrub the waveform directly. Freeze the grain cloud to hold a sound for as long as you want. Run the stereo delay to smear the grain tails into echoes; it syncs to tempo too. Export captures as WAV to the Files app. RECORD YOUR PERFORMANCE Start a recording from the presets menu and everything you play is captured to a WAV file. Keep playing through app switches and screen locks; a Lock Screen Live Activity shows while recording runs. Recordings save to the Files app and share straight from Field. PLAY IT AS AN INSTRUMENT Switch to Instrument mode and play the grain engine from a MIDI keyboard: four-voice polyphony, an attack/release envelope, and a root-note control. The pitch ribbon snaps to musical intervals: Free, Chromatic, Scale, Octaves, or Oct+5ths, with twelve scale options and a probability control. Works with hardware MIDI in the standalone app and with host MIDI in AUv3. USE IT IN YOUR HOST The AUv3 music effect loads in AUM, Logic for iPad, and other AUv3 hosts. Parameters are exposed for host automation and MIDI learn. Your patch saves and restores with the session, including head count, every per-head control, the modulation slots, and pitch snap mode. ALSO IN THE BOX - Ten factory presets grouped by character, with a browser and a Favorites section for your own - Background audio: the standalone keeps playing when you switch apps - Reverb, stereo delay with tempo sync, filter, grain-shape windows, pitch randomization - Runs on iPhone with a compact layout No account and no subscription. Field collects no data.

HeadStack is a multi-head tape delay inspired by the character, movement and musicality of classic magnetic echo machines, reimagined for modern production. At its heart is a virtual tape loop with 8 independently configurable playback heads. Each head can be positioned, levelled and panned to create everything from vintage slap-back echoes and rhythmic repeats to vast stereo soundscapes and evolving ambient textures. While HeadStack captures the warmth and unpredictability of classic tape systems, it is not limited by their mechanical constraints. Individual heads can be modulated, filtered, diffused, pitch-shifted and transformed into granular playback engines, opening up a palette that ranges from authentic analogue echoes to shimmering harmonies and cinematic atmospheres. The tape itself becomes an instrument. Rotate the head wheel to continuously reposition playback points, stretch the spacing between heads, introduce head loss, or create cascading feedback networks that evolve with every repeat. Independent filtering, stereo placement and modulation allow each head to develop its own character within the delay line. You can even play sequences Into HeadStack and freeze it using your hold pedal and continue to play over the top. Whether you’re searching for vintage tape ambience, rhythmic multi-tap delays, lush granular harmonies or experimental feedback textures, HeadStack combines the soul of a classic tape echo with the flexibility of a modern creative effects processor. Welcome to a new generation of tape delay. HeadStack Features: Multi-Head Tape Engine - Create complex rhythmic delays using multiple independently controllable playback heads running on a shared virtual tape loop. Vintage Character - Capture the warmth, movement and musical imperfections of classic tape echo machines with adjustable tape loss, filtering and feedback behavior. Independent Head Control - Each playback head features its own level, pan, timing offset and tonal shaping, allowing intricate delay patterns and evolving stereo textures. Rotating Head Wheel- Continuously reposition or stretch the virtual head arrangement to create shifting rhythms, moving echoes and dynamic performance effects. Granular Harmony Engine - Transform individual heads into pitch-shifted granular voices, generating harmonies, octave layers and shimmering textures directly from the tape loop. Per-Head Modulation - Add movement and expression with independent modulation of playback position, spacing, tremolo and stereo placement. Creative Feedback Routing - Choose between traditional multi-head feedback or route feedback from a specific playback head for unique echo patterns and evolving repeats. Diffusion & Smearing - Blend between precise rhythmic echoes and spacious, atmospheric washes using integrated diffusion processing. Deep Stereo Imaging - Create anything from focused mono echoes to wide immersive soundscapes with per-head panning, Haas delay and stereo enhancement controls. Performance Ready - Designed for real-time interaction, encouraging hands-on manipulation of head positions, modulation and feedback while performing. Precision & Experimentation - Dial in authentic tape echoes, lush ambient delays or push the engine into unpredictable granular and feedback-driven territories. Modern Workflow - Combines the immediacy of classic hardware with the flexibility, recall and precision expected from a contemporary audio plugin. Interactive Head Wheel - Grab and rotate the virtual head wheel to reposition playback heads, create evolving delay patterns and perform dramatic tape-style scrubbing effects. Dynamic Tape Warping- Enable Rotate and Stretch modes to continuously morph the spacing and timing between playback heads, transforming static echoes into living, breathing rhythmic textures. Freeze Buffer - Freeze the contents of the audio buffer using a foot pedal, capture ideas and play over the top.
