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.

JenDie is inspired by the legendary Jen SX-1000 — the classic Italian monophonic analog synthesizer of the late 1970s — reimagined for your iPhone and iPad. Every oscillator, filter, and envelope has been carefully modeled to recreate the warm, gritty, unmistakable character of that vintage analog sound, now in a modern, touch-first instrument. Use JenDie as a standalone synth or as an Audio Unit (AUv3) plug-in inside GarageBand, AUM, Cubasis, Logic Pro for iPad, and any AUv3-compatible host. KEY FEATURES • Faithful Jen SX-1000 emulation — true-to-hardware VCO, VCF, and envelope behavior, including analog drift for an authentic, living tone. • Authentic & Clean modes — choose vintage character or a cleaner, more precise sound. • Continuous waveform morphing — sweep smoothly between waveforms instead of switching in steps, with automatable control for evolving leads and basses. • Pulse width & PWM — shape and modulate the pulse waveform for rich, animated timbres. • 46 factory presets — from classic vintage leads and basses to new morphing patches designed for automation. • Full preset management — save, organize, and recall your own sounds; presets are stored in the Files app for easy backup and sharing. • Multi-touch keyboard — playable on-screen keyboard with multi-finger support. • Pinch-to-zoom interface — zoom and pan the panel for precise control on any screen size. • MIDI support — play JenDie from any connected MIDI controller, with a built-in MIDI Panic control. • Optimized for iOS — efficient DSP designed to run smoothly on iPhone and iPad. WHO IT'S FOR Whether you're a synth enthusiast chasing that vintage monophonic sound, a producer who needs a characterful lead and bass machine, or a sound designer exploring evolving textures, JenDie delivers genuine analog attitude in a portable package. Download JenDie and bring a piece of analog synth history to your mobile studio.
