Free web synths you can play in your browser. AUv3 plugins for your DAW. Music culture from the underground. Built by musicians, for musicians.
Play free in your browser. When you're ready, take it into your DAW as an AUv3 plugin for Mac, iPhone and iPad.
A browser-native synthesizer with wavetable oscillators, FM routing, and a built-in AI assistant that learns your sound. Sketch patches fast, refine with targeted adjustments — not full regenerations.
A markdown editor that thinks with you. Write, structure, and refine your music theory notes, lyrics, and production docs. The AI assistant makes targeted edits — tighten this paragraph, keep that voice — not full rewrites.
Drop a loop, slice it, pitch it, layer it. A fast browser-based loop workstation for quick ideas and break-chopping. When the idea is right, export the stems and take them to your DAW.
See your sound. Real-time audio-reactive visualisation that responds to every frequency, every beat. A creative tool for performance visuals and understanding the geometry of sound.
Every XenFM instrument comes with a built-in AI assistant that builds a model of you — your preferences, your patches, your workflow. It runs on its own private database, fully isolated, deletable, downloadable.
No more starting from scratch every session. No more explaining what you like over and over. The assistant remembers, learns, and makes targeted suggestions — not full rewrites that throw away everything you've built.
This is the same compactionless AI experience our own team uses daily. Now it's in your hands.
The geometry, science and soul of sound. From Gregorian chanting to modern tonic trance — the threads that connect all music.
Every scale, chord and progression lives on a circle of twelve points. This is the map. An interactive guide to the geometry beneath all music.
Geometric Music TheoryThe star pattern that generates all chord progressions. Why every song you love follows the same paths through harmonic space.
Sound CultureHow sacred monastic music cross-pollinated with modern electronic dance culture. The drone, the repetition, the altered state — a thread that runs through a thousand years of sound.
Sound CultureCymatics, Chladni plates, and the visual language of frequency. When sound becomes visible, the patterns are unmistakable — and they repeat across nature, architecture, and music.
UndergroundSix seconds of drumming that spawned an entire genre. How the Amen Break became the most sampled loop in electronic music history — and why it still matters.
UndergroundThe culture, the technology, and the community that built UK underground music from the ground up. A personal account from the transmitter room.
XenFM grew from the Brighton underground — the pirate radio culture that gave UK dance music its heartbeat. We built the infrastructure for the scene. Now we're building the instruments.
From sample packs with LabSamples and Erb N Dub, to artist platforms for DJ Rap, to a decade of work alongside the leading names in DnB — we've been part of independent music culture from the inside.
The radio will return. For now, we're building the tools.
