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's Workflow
Find
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.
Perform
Expressively play sample-based instruments: velocity, modulation, and pitch bend work as expected. Use MIDI controllers, DAW automation and Floe's macro knobs to further create lively performances.
Transform
Take sounds beyond their natural boundaries. Layer instruments across libraries, sculpt with loop and crossfade controls that bridge multisampling and synthesis, then process through built-in effects.
Key Benefits
Layer across libraries
Break free from single-library limitations. Floe's 3-layer architecture lets you blend instruments from completely different sample libraries, creating rich, complex textures.
Sample-based synthesis, not just playback
More than a sample player — Floe features synthesis capabilities with filters, envelopes, LFOs, and crossfade controls. Take sounds beyond their natural boundaries, creating textures impossible with the original recordings.
Professional effects rack
Shape your sound with 11 high-quality effects in customizable order, including pro-standard reverb and delay. Each layer processes individually before flowing through the shared effects chain.
Works with your workflow
Flexible folder management adapts to your organization, supports external drives, and instantly detects changes. No rigid requirements — Floe allows you to manage files your way.
No accounts, no subscriptions, no interruptions
Focus entirely on your creative process. Floe works offline, respects your privacy, and never interrupts your workflow with authentication prompts or payment reminders.

About Floe
Widely supported
A sample-based synthesiser/ROMpler 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), and 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 encapsulated 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.
