Slow draws from the sound design of ambient pioneers like Tim Hecker, Boards of Canada, Stars Of The Lid, Oneohtrix Point Never, Mark Pritchard, and Benoit Pioulard. While each artist explored different avenues of ambient music, they share a breathless multitimbral complexity—often richer in overtones than Brian Eno's foundational work. We've captured these sonic elements to create a versatile tool for ambient and cinematic music.
Each of Slow's 63 oscillators was carefully crafted from synthesizers, granulizers, and organic sources. You'll find subdued ambient tones alongside sounds with lush high frequencies, feedback qualities, and rich overtones.
The sounds are organised into two categories: Tonal and Textures. Tonal forms the core, featuring pleasant single-note instruments with occasional dissonant or multi-note variations. Textures provides noise elements designed to layer with tonal sounds and build immersive soundscapes.
Slow includes 100 production-ready presets across six categories: Basses, FX, Keys, Noise Textures, Pads, and Pulsers—with Pads as the centerpiece. Each preset is a playable instrument, ready to use as-is or easily tweaked to fit your track. Beyond ambient pads, Slow can fill out low end, add haunting textures, or provide tonal accompaniment.
Slow has been updated as a Floe native format library with comprehensive tagging across all 100 presets and 63 instruments, improved audio quality with fixed pops, and refined tuning for noise textures. Several presets have been renamed for clarity: Slow Pulser → Noisy Strings Pulser, Bizarre Pad 1 → Singing Wind, Bizarre Pad 2 → Busy Textures, Chilled Key 1 → Synth Key 1, Chilled Key 2 → Synth Key 2, Subtle Hiss Pad → Indian Fire, Slow Bass → Octaved Bass. The update is fully backwards compatible—existing presets and DAW projects will continue to work seamlessly.

Slow runs inside Floe, our free, open-source plugin for Windows, macOS, and Linux.
Blend instruments from any library in a single patch. Floe's three-layer architecture, each with its own controls, allow for creating hybrid textures.
Create advanced rhythmic performances. Each layer can run its own arpeggiator — different rates, rhythms and patterns playing against each other.
Stretch, freeze and reshape any instrument into evolving clouds and textures — even multisampled instruments.
Eleven high-quality, reorderable effects — including pro-standard reverb and delay, and covolution reverb with creative IRs.
Four macro knobs for expressive performance of multiple parameters. MIDI CC, sustain pedel, undo/redo, A/B comparison for preset edits, visual EQs and a random variation generator.
Floe is a companion project to FrozenPlain — totally free and open source for longevity and ethical service to the music-making community.
Carefully updated for Floe, this library was originally made for Mirage, Floe's predecessor.
146 presets (complete production-ready patches) in Slow Factory Presets (v1.2).
