Local-first
Offline by default. Your prompts, lyrics, and tracks never leave the machine unless you explicitly send them.
Iblis
A free, open-source, local-first AI music workstation for Windows 11. Generate songs, train your own styles, and organize it all on your own GPU. No accounts. No cloud. Plugin-shaped everywhere it matters.
Public beta 0.2.0-alpha.59. Free, open source under GPL-3.0-or-later, Windows 11 with an NVIDIA GPU, no accounts.
BETA
It makes songs today; it is not finished. The code went public on 2026-09-25. Expect rough edges, a SmartScreen warning on first install, and features that are still on the list below. Anything odd: tell us, no account needed, and watch it move on the public board.
The installer is the official build: it auto-updates over signed releases and uses the official catalog. Copies you build from source are unofficial, unsigned, and do not auto-update. Building from source.
Where it stands
Shipped means shipped in the installer you can download now. The full list, with reasons and order, is the roadmap.
Works today
- Generate full songs on your own GPUText to music with lyrics or instrumental, a negative prompt, bpm and key, and a queue that survives restarts.
- Library with waveforms and provenanceFolders, search, remix from any take, and a player that follows you across the app.
- Train your own StylePoint it at a folder of your songs and train a LoRA on an 8 GB card. Texture and Groove styles, then generate with them.
- Community StylesBrowse styles others trained, each behind an explicit acknowledgement. Publishing and downloads use a product key.
- Four built-in BPM and key detectorsPick the one you trust; every result names its detector and license.
- Live skinsFour skins, an in-app token editor, and a contract that lets any skin style any plugin.
- Signed, hot-swappable pluginsEngines, processors, and skins install from a signed catalog and roll back atomically.
- Signed auto-updatesEvery update is checked against a key built into the app before it installs.
- Bring your own cloud keyOptional song ideas and lyric help through OpenRouter, with the price shown before every request.
- Local by defaultNothing leaves the machine unless you send it. Diagnostics are opt-in.
Coming next
- Extend, edit, and remix a takeThe engine can already extend; the listen gate decides when it ships.
- Stem splitting and cover artVocals, drums, bass, other; covers from a signed image plugin.
- A second engine, and one that singsAn audio.cpp pack, then a vocal model for the 8 GB tier.
- First-run good defaultsProbe the GPU, pick the engine pack, get to a first song without a wrong turn.
- Frequency-coloured waveformsA bounded spectral sidecar and low, mid, high skin tokens.
- Windows code signingUntil then SmartScreen warns about an unknown publisher on first install.
What it looks like
Real captures of the current build in the default Dark 3D skin. The skins page shows the other three.
Modular
Audio engines, stem splitters, image generators, visualizations, and skins are all swappable plugins. Replace any of them without reinstalling the rest.
Skinnable
One closed token vocabulary. Any skin styles any plugin, and any plugin reads any skin. Edit themes in-app, swap them live.
Open source, from today
Read it, build it, change it
The desktop app is GPL-3.0-or-later, the plugin SDK Apache-2.0, the first-party plugins MIT. Issues, pull requests with a DCO sign-off, and the security policy are all in the repository. What is open and what is hosted.
Plugins
Versioned folders on disk. Hot-swap with an atomic current.txt pointer. Eight kinds: engine processor image-gen cloud-provider visualizer ui-pack skin training.
Community services
Everything that runs on your machine is free and never needs a key: generation, training your own styles, the Library, playback, skins, plugins, and anything you have already downloaded.
A product key is only for the parts that run on our hosted infrastructure: publishing styles to the community Styles library, downloading community styles, and uploads. Hosting installers and community styles already runs to dozens of gigabytes and keeps growing, so keys are issued by email while capacity is limited.
To ask for one, email Iblis-Beta-Test@meiuxmeiux.com with your GPU and basic hardware specs (an NVIDIA GPU with 8 GB of VRAM or more is recommended for training) and a little about what you want to make.
