Floe - Sample Library Platform

Find, perform, and shape sounds beyond their natural boundaries. A free, open platform that puts sound transformation at your fingertips – built with care and simplicity in mind.

Floe is a free audio plugin for your digital audio workstation (DAW). It is the engine for a growing catalogue of Floe format sample libraries, offering easy playback of sample-based instruments. But it's more than just playback — Floe allows you to transform the sounds using easy-to-use sample-based synthesis features: layering, looping, granular, FX and more.

Open platform

Floe is an open platform for Floe-format sample libraries, providing a streamlined workflow for finding, performing and transforming sounds.

It’s designed for producers, composers and musicians. But additionally, developers with programming experience can use Floe's open tools to build sample library products for the platform.

User-friendly

Our philosophy is to be hassle-free and allow you to focus on what really matters: making beautiful music.

• Offline installation
• Open source (GPL license), no accounts, no subscriptions, no interruptions
• Visual UI: see what's happening in the sound
• Resizable vector UI
• Flexible folders — supports external drives and instantly detects changes

Find the right sound

Floe's unified browser works across all your libraries with comprehensive search, tags (mood, type, genre), and categorisation. The sound you need is always a few clicks away, whether you're hunting for something specific or exploring new territory.

Performance-ready

Expressively play sample-based instruments: velocity, modulation, and pitch bend work as expected. Use MIDI controllers, DAW automation and Floe's macro knobs to shape lively performances.

• A/B comparison for preset edits
• Undo/redo
• MIDI CC mappings
• MPE compatible
• Velocity to volume curve
• Settings for fully reproducible recordings

Transform with sample-based synthesis

Take sounds beyond their natural boundaries. Layer instruments across libraries, sculpt with loop and granular controls that bridge multisampling and synthesis, and process with built-in effects.

• 3-layer architecture
• Powerful granular synthesis
• 11 reorderable effects
• Per-layer arpeggiators
• Add loops with crossfade
• Envelopes, filters, LFOs
• Random variation generator
