Lacuna

Updated: 2026-10-26
What is Lacuna?
Lacuna puts composition, lyric writing, MIDI editing and track splitting into a single workspace, which its official website calls a "one-stop AI audio studio". Instead of giving you a single input box, it deploys several specialized agents for different stages: a music agent writes songs, a lyrics agent revises words, a MIDI agent drops notes on the piano roll, $1 Strudel agent writes code live in the browser sidebar. Describe what you want, and it gets to work—lyrics, notes and code all remain in editable interfaces, and you can take over at any time without waiting for it to finish everything before making revisions.
Who is it for?
- Independent musicians who have melody ideas but struggle with arrangement.
- Advertisers and short video soundtrack creators who need to quickly produce demos for client auditions.
- Lyricists who get stuck when writing and want someone to revise their drafts at any time.
- Developers who need original background music for podcasts and indie games.
- Strudel users who want to learn live coding music and need someone to explain the code.

Stems & Voice Cloning
Stems and voice cloning are available on the platform. The official recommendation is to record 2 to 30 minutes of material from a single singer, with 10 to 20 minutes covering the vocal range for the best results.
One account, one set of credits
All agents share the same account and credit balance, eliminating the need to recharge each tool separately.
How to use Lacuna
