An MCP client such as Claude can add tracks and edit MIDI and effects. Changes appear in llmuse and can be undone with Ctrl+Z.

Questions and answers

Windows SmartScreen warns me when I run the installer.

The installer isn't code-signed yet, so SmartScreen can't verify the publisher. Before you run it, get the file's SHA-256 with Get-FileHash in PowerShell and compare it with the value under Check the file below the download button. If they don't match, don't run it, and download it again from this site.

Does it run on macOS or Linux?

No. llmuse runs only on 64-bit Windows 10 and 11.

Can I use my plug-ins?

Yes, 64-bit VST3, CLAP and VST2 plug-ins. llmuse looks in the standard folders and the VST folders FL Studio installs, and you can add your own. FL Studio's own Fruity plug-ins only run inside FL Studio.

Does stem separation upload my music?

No. Stem separation runs on your PC and doesn't use the internet. HTDemucs comes with the installer, and the UVR vocal model is downloaded once, during setup or in the app.

Can I release songs made with the virtual singer?

Every voicebank has its own terms. For example, companies need a separate contract to use Kasane Teto, and Song-SoRi asks you to talk to its maker before earning money with it. llmuse shows a summary and a link to the terms before you download, but terms can change, so read the original before you release.

How do I connect Claude?

Install llmuse, then register llmuse-mcp.exe from the install folder as an MCP server in Claude Code or Claude Desktop. The exact command and settings are in USER_GUIDE.en.md in the same folder.

Does llmuse update itself?

No. Once a day it checks a small version file on this website and tells you when a new version is out. It never installs anything by itself, and you can turn the check off in Settings.
