Musica VJ is a desktop app for musicians, producers and DJs. It generates a live, evolving beat in real time and lights up the screen with visuals that react to your music automatically — no timeline, no VJ software, no second laptop.
No account needed to start. Works fully offline in local mode.
What it does
No music-tech jargon required — here's what actually happens when you hit play.
Generates a live, endless beat and music bed in real time. Steer it with a genre, a mood, or 20+ ready-made styles — or just let it drift.
Eight audio-reactive visual scenes light up in sync with your set automatically. No keyframes, no rendering, no separate VJ rig.
Four live macros — Motion, Atmosphere, Sculpture, Ribbon — reshape the whole look in real time, plus a full effects rack: echo, reverb, drive, crush, filter sweep.
Any MIDI controller, your keyboard, or the Logitech MX Creative Console maps straight to tracks, scenes and macros — no setup file to write.
Desktop app vs. this page
Everything here is free — the difference is what a browser tab is allowed to do versus what a real desktop app can do. Here's exactly what needs the install.
The actual DJ + VJ rig
The tour
Install this page for one-tap access — then download the desktop app for the full DJ+VJ rig.
Curious what the visuals feel like reacting to a beat? This is a silent preview — no audio, no AI generation, just the render engine.
One click, full vibe
Each template dials in tempo, beat pattern, visual scene and mood in one move — pick a vibe and keep performing.
The visual bank
Switch scenes live, layer in VJ presets like Peak Rave or Cinema Fog, or hand it to the shuffle button and keep your hands on the music.
Share the moment
Hit record and export a clip sized for TikTok, Reels or Stories — vertical or square, straight out of the app. No screen recorder, no editing software.
Inside the studio
Music decks, visual bank and live controls, all in one window.
