Lacuna

What is Lacuna?

Lacuna is an AI song and music creation platform. A user starts with a line, lyric, mood, genre, tempo, instrument idea, or rough concept, and the system generates a complete track with vocals, melody, harmony, and instrumentation. The resulting music can be extended, remixed, or rewritten by region, while stem tools separate vocals, drums, bass, and other layers.

The wider workspace includes an AI lyrics assistant, MIDI generation and editing, sheet-music conversion and scanning, album-cover generation, and developer access through an API, TypeScript SDK, MCP server, and command-line toolkit. Users must have rights to every uploaded input and must not imitate real artists or voices without permission.

How to Use Lacuna

1. Describe the genre, mood, tempo, instruments, vocal style, and song concept, or provide original lyrics.
2. Generate a draft and listen for composition, pronunciation, structure, and artifacts.
3. Extend, remix, or rewrite selected regions instead of regenerating the entire track.
4. Split stems when individual vocals or instruments need editing.
5. Add lyrics, MIDI, notation, or cover art inside the workspace.
6. Confirm ownership of all inputs and obtain the appropriate commercial license before publishing.

Frequently Asked Questions

Can Lacuna generate songs with vocals?

Yes. The platform generates complete tracks with configurable vocal style, gender, and tone.

Who can use generated music commercially?

Does stem separation grant rights to the original song?

No. Separating a recording does not create ownership of source material the user did not already have rights to.
