Grainsmith Field

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 the experience is optimized for iPad and iPhone. Field is a single multitouch screen designed to be played: four XY pads control paired parameters (Density and Size, Jitter and Spread, Scan and Reverse, Cutoff and Resonance), and a Morph control sweeps several at once.

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. Export captures as WAV to the Files app.

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. 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, and your patch is saved and restored with the session.

ALSO IN THE BOX
- Ten factory presets extracted from the desktop Grainsmith library, plus save and recall for your own
- Background audio: the standalone keeps playing when you switch apps
- Reverb, filter, grain-shape windows, pitch randomization
- Runs on iPhone with a compact layout
