The studio
Everything happens on your machine — no uploads, no waiting rooms, no monthly fees.
Paste a video or music link — Vimeo, SoundCloud, TikTok, Twitch, Bandcamp and more — or a full playlist. Every track arrives with its own artwork and saves as its own project. Batch-process an entire setlist while you grab coffee.
Vocals, drums, bass, guitar, piano and other — separated by the state-of-the-art Demucs model, with two quality presets: Standard for speed and High for deeper isolation.
Per-stem faders, mute and solo, clickable waveforms, and a condensed view that packs every stem into a slim chip while keeping all controls accessible. Jump anywhere — every track and video follows instantly.
The video plays in a true, draggable desktop window — locked frame-by-frame to the audio clock. It is muted by default so the stem tracks play the full sound.
Open a live frequency spectrum for any stem — peak-hold trails, real-time response. Then click Display All to send every instrument full-screen onto a second monitor in a gap-free grid: 3 rows, 3 or 4 columns, 2×2, 5 columns, or 6 equal boxes. Click anywhere in a cell to cycle its visual style; double-click to repaint it in a new color.
Saved projects regrouped by playlist, in compact or large views, sorted by newest, A→Z or Z→A. Export the whole thing as a folder or ZIP. And the whole studio answers to musical keys — V/G/B/D/P/O to mute a stem in a heartbeat, Shift to solo, M to mute all, S to clear solos. Space to play. That's it.
Ctrl-click a few songs in your library to build a play queue, hit play, and get out of the way — when one song ends, the next loads and starts itself. Your set list, on autopilot.
Near-silent stems are detected and dropped automatically, so the deck never shows dead weight. A sparse acoustic track arrives as the two or three real instruments that are actually there — not a wall of empty channels.
Frameless, auto-hiding chrome — the toolbar fades away after a few seconds so nothing stands between you and the music. Hover to bring it back. The instruments, the video, the waveforms: that's the interface now.
One click to studio
Drop in a video or music link — a single, a full playlist, an album or a live set. It downloads named from the real title, with its own artwork. Or open a file from your hard drive.
Demucs splits the soundtrack into six instrument stems. The loading overlay shows each stem as it arrives, then fades to reveal the deck — and whispers the BPM and song key in the corner.
Single Stem Visuals can play in their own window or separate monitor. Or choose to display up to six stem visuals in a 2×6 or 3×3 arrangement on a separate monitor.
The separation
Click a lane. Watch what the AI pulled out of a single stereo track.
Pick a preset to shape the trade-off: Standard · six stems, fast · High · deeper isolation. All presets keep your machine light — the AI engine is capped at 80% CPU so you stay in control.
True multi-window
See Song Studio drives the video into real OS windows, synced to the same clock as the audio. The interface itself is a frameless, auto-hiding chrome — the video is what you see, not the app chrome.
INSTRUMENT MONITORS · open a live spectrum per instrument with peak-hold trails. Click anywhere to cycle through 6 visual styles — bars, wave, radial, LED — and double-click to repaint the whole window in a new color.
Full-screen layout
Click the ▦ Display All button on the master video row — the app picks the best layout for your stem count and opens a gap-free, full-screen grid on a 2nd or 3rd monitor. Cycle through preset arrangements with every click.
Full-width spectrums stacked — ideal for wide monitors. Stems fill the screen edge to edge.
Four slim columns, full-height. A great everyday arrangement for four or more stems.
Three equal columns side-by-side. Great for portrait monitors or narrow displays.
Four equal quadrants. Perfect for a balanced four-stem view of your mix.
Five slim columns, full-height. For projects with five instruments or more.
Three columns, two rows — six equal boxes for every stem in your project.
Each cell draws a live colored spectrum. Click the cell's title to cycle its visual style — Bars, Mirror, Wave, Radial, LED, Center. Every stem, your choice.
Batch playback
From "Load Playlist" in the menu to a library full of projects — the app downloads, separates, and saves every track in sequence, one by one, with a live progress window that shows each track's status, time estimate, and artwork.
After fetching the playlist, choose exactly the tracks you want with checkboxes. Select all, deselect, start over — the UI shows every track with its artwork and duration.
Tracks process one by one: download first, then separate with Standard quality. Each step updates the live progress bar and ETA.
Click any queued row to cancel it before it starts — the row turns grey and is skipped. Perfect for when you don't want to wait for the last few tracks.
When done, a summary shows every project's runtime, file size, and stem count — plus totals for everything. Projects are stored in the library grouped by playlist title.
During long builds the separation engine is capped at 80% CPU usage, so you can keep working or browse while the playlist processes.
Always at your fingers
Your playlist of shortcuts is musical, not cryptic. Every letter matches the instrument.
The keyboard map overlay in the app shows every shortcut with illustrated keycaps. Instantly accessible from the ☰ menu.
