For venues & spaces
A backdrop that reacts to whoever is singing
Static color washes and looping stock footage treat every song the same. SYQEL listens to the room and responds to the actual audio — so the screens behind a quiet ballad look nothing like the screens behind a rowdy group finale.
Free to try · Windows & macOS · No card required
Karaoke is participatory entertainment, and the visual energy in the room should match whoever is on the mic. A shy first-timer needs a different backdrop than a table of regulars belting out a rock anthem. SYQEL reads the live audio feed from your system — vocals, backing track, crowd noise — and drives visuals that rise with the energy, pulse with the beat, and settle back down during quiet moments. There are no clips to cue between songs and no operator babysitting the screen. Set up a playlist of high-energy looks, and let the room run itself.
How SYQEL works with karaoke bars
Feed it your karaoke audio
Connect SYQEL to your karaoke system's audio output — a line out from the mixer or the room's PA return — and it starts reading beats, vocals, and crowd energy instantly.
Choose per-room looks
Each private room or the main stage can have its own set of approved visuals — wilder for the main floor, slightly calmer for private booths — saved and ready for staff to run.
Let the night run itself
With a visual playlist active, SYQEL cycles through looks automatically between songs and reacts to each new performer without any manual intervention.
Reacts to every performer
Because it listens to live audio, each singer gets a backdrop that matches their actual energy level — no two songs look identical.
Per-room screen control
Output to individual room screens or a main stage wall independently, so private booths and the open floor each get an appropriate visual mood.
No clips to cue between songs
There are no video files or timelines to manage. Visuals run continuously and react to whatever comes through the audio feed, so transitions are seamless.
Theme nights on demand
Generate a custom look for 80s night, Latin night, or a private party in seconds using the AI visual generator — no design skills needed.
What's in SYQEL Desktop
The parts DJs use every night — each one documented, none of them extra software.
Works offline
Visuals, playlists, logos and hotkeys live on your machine. No internet at the venue, no problem — the show runs exactly the same. Sign in on another machine and your setup follows you.
Five visual feeds
Worlds, shaders, scenes, Milkdrop and image visuals — hundreds of looks in one library, every one of them reacting to the music in real time.
Control with MIDI or keyboard
Space for the next visual, Enter to hold one for the drop, Backspace to go back. Put any control, visual or playlist on a key or a pad with Learn Key and Learn MIDI — on every plan.
Broadcast and NDI
Press B for a clean output window to capture in OBS, or send the visuals over your network with NDI into OBS, vMix or Resolume — Spout too, on Windows.
Create visuals with AI
Describe a look — "neon hexagon tunnel that pulses with the bass" — and get a brand-new audio-reactive shader, or generate an image and let the AI animate it. Adjust it for free, keep what you make.
Record four formats at once
Press R and SYQEL saves four videos in one go — 16:9, 1:1, 9:16 and 4:5 — with your audio in them, straight into a SYQEL folder. One for every platform, nothing to capture or convert.

Frequently asked questions
Can SYQEL run on multiple screens in different private rooms?
Yes. You can run separate instances or use NDI to route different visual outputs to different screens. Each room can have its own preset list so staff can set the mood per space without touching the main system.
Will it work with our existing karaoke software and AV setup?
SYQEL outputs over NDI, Spout (Windows), and Mac Screen Share, so it can feed into most AV rigs as a video source. It takes a standard audio input, so any mixer with a line out will work.
What happens between songs when there's no audio?
SYQEL reads the ambient room sound, so low-level crowd noise and chatter still drive subtle movement. You can also set a calm idle visual that activates during quiet moments.
