DAW for Windows
llmuse is a DAW for recording vocals over a backing track and editing them. You can also write parts for a virtual singer, split songs into stems, use your own plug-ins and let an AI assistant work in the project with you.
In PowerShell, run Get-FileHash on the downloaded file and compare the result with this value.
Three modes
Switch modes at the top right of the window. Easy records a song in four steps, Pro is the full editor, and Karaoke is for singing along.
Load a backing track, record, mix and export in four steps across the top. llmuse detects the tempo and key and keeps every take. A genre preset, Auto-Tune and one-click mastering finish the mix.
The full editor with the playlist, mixer, piano roll, step sequencer, vocal editor and loop station. You can hide the browser or open any bottom panel in a separate window.
Large lyrics light up in time with the song. You can change the key and tempo, add echo and turn on a guide melody. Record while you sing to get a score.
Vocals
Every recording becomes a take. llmuse checks each take, sets its level and tells you what to change next time. Fix notes one at a time in the vocal editor, or use Auto-Tune in real time.
MIDI and instruments
The piano roll has lanes for velocity, sustain, sostenuto and soft pedals, modulation, expression and pitch bend. Score View shows the same clip on a grand staff.
Mixing
Every strip has a channel EQ, inserts and sends. Tracks fold into groups, and the compressor and gate can take a sidechain from any track. The main effects are set by dragging handles on a large graph.
Mastering
Pick a template for a platform or genre. llmuse renders and measures the song, sets up the master chain and shows the result in LUFS and true peak. Switch between Before and After to compare.
Stem separation
HTDemucs, which comes with the installer, separates vocals, drums, bass and other parts. Separation runs on your computer, so nothing is uploaded.
Karaoke and lyrics
Open an LRC file or paste lyrics, then tap along to time them. Lyrics you apply are saved to the Lyrics Library, and the best match loads when you open the same backing track again.
More features
Click to place the edit cursor, drag to select a range across tracks, then cut, copy, ripple delete or split.
Change the tempo or the time signature at any bar, and ramp the tempo smoothly. The grid, metronome, recording and export follow.
Loop recording puts each pass on its own take lane. Drag across a lane to use that take there, then flatten when you're done.
Change speed like tape or keep the pitch, and reverse audio and MIDI clips. Audio is always rebuilt from the original.
Fold tracks into groups, nest them, and mute, solo or level them together like a bus.
Record loops in time with the song, stack overdubs, then move them to the arrangement.
Use your 64-bit plug-ins with their own presets, A/B and extra outputs. ARA 2 editing of audio clips is experimental.

Switch the interface language at any time, with full Korean input support.
Start from the llmuse, FL Studio style or Ableton style key map and change any key.
Drag a point in an audio clip to fix its timing, or move every attack to the grid. The pitch stays the same.
Draw a volume curve inside an audio clip. It stays in place when you trim or split the clip.
Right-click a knob, fader or transport button and move a control on your MIDI controller to map it.
Start a song from a template, or save tracks with their instruments and effects to use again.

AI and MCP
llmuse comes with an MCP server, llmuse-mcp. Claude and other MCP clients can use it to create tracks, write parts, tune the virtual singer, mix, master and export.
They cover tracks, notes, mixing, mastering, stems, lyrics and export.
With llmuse open, edits show up as they happen, and Ctrl+Z undoes them one by one.
Connections stay on 127.0.0.1. Before any download, the assistant has to show you the terms and ask.
Composition notes, 15 genre guides and a vocal tuning guide teach Claude to work in llmuse.
Start a lo-fi song at 80 BPM with soft piano chords, a lazy drum loop and a bass line, then master it for streaming.

Virtual singer
Put lyrics on notes and a UTAU voicebank sings them in Japanese or Korean. The installer can download free voices from their official sites, so it can sing right after you install.
Open Virtual Singer Example on the start screen to hear it.
System requirements
llmuse runs on most Windows PCs. Use headphones when you record, and an audio interface for the lowest latency.
FAQ
The installer isn't code-signed yet, so SmartScreen may warn the first time you run it. Click More info, then Run anyway. To check that the download is complete and unchanged, compare its SHA-256 with the value under Check the file below the download button.
No. llmuse runs only on 64-bit Windows 10 and 11.
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.
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.
That depends on the voicebank's terms. The free Namine Ritsu voicebank allows commercial use without credit. Every voice has its own terms, and llmuse shows a summary and a link before you download.
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.
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.
