Overview

Lacuna is an AI music generator capable of creating full songs from lyrics or text descriptions. It can generate songs with vocals in various genres. Additionally, it includes a variety of tools such as an AI MIDI generator that generates playable MIDI from a text prompt, a MIDI editor for composing and editing music, and a sheet music scanner that turns photos into scanner-quality sheet music.

The platform's AI music generator is capable of producing songs based on user-provided lyrics, or a user can describe their vision for a song and the AI will generate a complete track with vocals, melody, and instrumentation.

The AI parses the emotion, style, and rhythm from this description to create the music. Lacuna's lyrics studio offers features such as real-time syllable counting for precise rhythm control, automatic end-rhyme detection, and AI-assisted co-writing for when users need help continuing, rewriting, or suggesting rhyming alternatives.

The platform also provides music DNA, where AI generates professional parameters that users can fine-tune at any time. Furthermore, Lacuna offers a collection of AI-generated music samples across various styles for users to explore and gain inspiration from.

Users can start from a simple description of the music they want, and the AI transforms it into a complete track.
