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.
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
- 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

About Floe
Widely supported
A sample-based platform available as a CLAP, VST3, or AU plugin for Windows, macOS, and Linux. Compatible with all major DAWs — Logic Pro, Cubase, Studio One, FL Studio, Ableton Live, Reaper, and more. Uses the open Floe sample library format.
Yours to keep
No accounts, no subscriptions, no interruptions — your libraries live on your machine in an open format. Because Floe is open-source (GPL), it can keep working indefinitely, so your creative workflow won't disappear because of business decisions.
FrozenPlain
Floe and FrozenPlain are companion projects — both created by Sam Windell, with FrozenPlain's cinematic and ambient libraries primarily shaping Floe's direction. However, Floe is intentionally kept as its own open platform, free to explore wider applications and serve the broader music-making community.
Openly built
Floe is an outlet for a broader passion — open-source, ethical software built for real longevity — with its library-creation tooling (in Lua) freely available to other developers and the wider open-source community.
Built on a proven foundation
Floe builds on the architecture of FrozenPlain's Mirage, refined through years of professional use and shaped by direct feedback from composers working in film and television.
