Forces
Shape the paths your sound takes.

Sound as falling matter
A visual granular instrument that turns sound into moving particles. Shape their paths with forces and objects to create rhythms, textures and evolving soundscapes.

What you see fall is what you hear.

Matter / Field turns a sound into a field of moving particles. In FALL mode, each collision plays a grain, a tiny piece of the source sound, shaped by the material it strikes. In CLOUD mode, the grains sound as they travel. The same physics shapes the picture and the sound.
Start with a built-in sound and one of 101 studies: ready-made scenes you can play, change and save. Adjust the forces, objects, rhythm or room. Keep the result in key, play it from a keyboard, or let it evolve over time. The native app also lets you use your own recordings and live audio.
It comes from the particle effects Cyrus Makarechian made in Maya and Houdini: he always wanted to design sound the same way, so he built it.
On iPhone and iPad, Matter / Field is also an Audio Unit (AUv3) instrument for music apps such as GarageBand, and on the Mac, an app and an AU, VST3 and CLAP plug-in. A MIDI note lets matter fall in its pitch, and the field follows the host’s tempo and transport. Its strikes can play your other instruments too: MIDI out sends a note for each, and in hosts that support multiple outputs, each emitter has an output of its own.
Installed, it collects nothing and needs no account and no connection.
