A new sound world — every time you open it

Playful instruments for cinematic and electronic music. A growing library with new additions every week.

FFOSSO instruments showcase

Made to eliminate the generic

For creators who are sound explorers. For creators who refuse to reach for the same sounds everybody uses.
FFOSSO instruments are built from explorative recording sessions — from Balinese gamelan and spectral string textures to physical resonating bodies. Organic, full of character, and impossible to find anywhere else.

Waste

An extensive collection of field recordings by sound artist Jacob Kirkegaard. Sampled in waste facilities worldwide, Waste features four mixable sound sources with detailed industrial textures and evolving drones.

The plugin that's always current

Weekly new additions with FFOSSO Pro and over 100 recently built instruments let your sound palette stay current — long after most libraries have started collecting dust.

Introducing FFOSSO

Customize your instruments

FFOSSO puts organic, acoustic, and layered sounds in motion. Each instrument and sound source has its own story, with layers that bend, collide, and re-shape in real time. Expressive engines reward exploration, delivering sounds that feel tactile, responsive, and distinct—built for experimentation and controlled variation, with texture, depth, and movement across every element.

Modular by designBETA

FFOSSO offers a fully modular environment that combines multi-sampling, synthesis and effects. Choose from a growing library of modules.

Elements to design your own instrumentsBETA

Tap into a vast library of pre-mapped multisampler presets through the FFOSSO cloud — to shape expressive instruments by stacking, sequencing, and sculpting with powerful functions and DSP tools.
