Just installed? Start here
You installed Song Serpent plus KaraFun and/or VirtualDJ. Song Serpent is the host screen—search, queue, rotate singers, and change keys from one place. Your engines still play the audio.
Stop juggling engine windows. Song Serpent is the desk you host from — search, queue, rotate, and run the room while KaraFun and VirtualDJ keep playing the audio.
Requests land in a single host queue. When a track is up, Song Serpent hands it to the right engine so you’re watching the singers, not the taskbar.
Keys, rotation, intermission, and Fangcast™ live on the same screen you already use to run the show.
Song Serpent is a desktop host app. These are the floors we ship against today.
Wire VirtualDJ and KaraFun in Settings first. Song Serpent doesn’t replace those subscriptions — it searches the catalogs you already pay for and adds picks to one host queue. The engines still play the audio.
VirtualDJ Pro plus the Network Control plugin so Song Serpent can drive VirtualDJ over HTTP.

Song Serpent shows and hides the VirtualDJ video window for you — no hand-toggling when KaraFun takes the floor.
An active KaraFun subscription with remote control on. Paste the room URL or code into Song Serpent; playback audio stays on the KaraFun host.
Song Serpent → Settings → enable each engine, Connect, then you’re ready to search.
Type a song. See KaraFun and VirtualDJ together. Add it to the shared lineup and Song Serpent sends it to the right engine when that singer is up.
Results show title, artist, and which engine has the track. Pick a row, pick a singer, and it’s on the host queue — not buried in a second window.
Song Serpent auto-manages the VirtualDJ video window — closes it when KaraFun plays, opens it again for VirtualDJ tracks (Settings → VirtualDJ → Video auto-manage).
Keep a singer list on the side. Smart rotation places new songs so walk-ups get a turn without cutting the line. Override anytime a VIP, duet, or fixed order walks up.
Leave it on and Song Serpent places requests so everyone gets a fair turn without you reshuffling every time.
Take the wheel when the room needs it — VIP walk-up, duet next, or a locked order for the hour.
When you add a song, Song Serpent suggests a smart position from Settings. Change it in the add dialog for that song only.
Transpose KaraFun and VirtualDJ from Song Serpent — no diving into each engine mid-request.
Open Advanced on add to set key and tempo. KaraFun also exposes lead/backing vocal levels.
Edit a queued song anytime before it plays to change key or tempo.
On the now-playing song, Adjust key / tempo changes pitch while they’re already on stage.
Phones up. The crowd talks to the singer. Guests scan a QR and tap Love and Hype — and Roast when you flip Roast mode on — and those reactions blast onto the singer display with live tallies while the song is still going. No app install. No guest accounts.
Share a QR or short link from Settings → Fangcast™. Guests open it in the browser and they’re live. Add tip links (Venmo, PayPal, Cash App…) and socials when you want the guest page to work the room for you.
One vibe per device per song — only while audio is actually playing. Pause or between songs, they wait instead of staring at a dead title. Front-row devices unlock mystery and bank a 1UP for a second vibe later.
Flip Roast on and guests get Down, Laugh, Tomato, and Rage next to Love and Hype. Nice vs roast tug-of-war can wash the display in Fire or Tomato — mutually exclusive, and you can force either from the KJ toolkit.
Reactions fly across the singer display as they land. Hit celebration thresholds (5 / 15 / 30 by default) and that emoji bursts big. You set the thresholds; the room supplies the noise.
Open a Cheer window so the room can spam reactions for a few seconds, Boost a singer, light Fire or Tomato, show or hide the QR, unlock mystery for the whole room — all from the queue player while the song is still going.
Net reaction scores pile up so you can crown Song of the Night and run a recap when the last singer sits down. Device counts show phones in the room — never names.
Privacy stays boring on purpose — no guest names, anonymous device ids hashed on our servers, one vibe per browser per song. Private windows can watch but cannot vibe. See the Privacy Policy.
Fangcast™ is a Pro feature.
Drop non-karaoke tracks between singers in the same queue. The room stays loud; you stay in Song Serpent.
Park DJ / walk-in music between karaoke songs so you’re not flipping to another app when the next singer isn’t ready.
Intermission tracks in the queue are a Pro feature.
When the last singer sits down, you’ve still got the record — not just a cleared queue.
What played tonight (singer, song, engine), with CSV export when you need a report.
Top songs and singers, plus KaraFun vs VirtualDJ breakdown, for tonight, this week, or all time.
You can try Song Serpent with a small freemium singer limit. A Pro license removes that cap when you are ready.
Engine subscriptions and public-performance licenses are still your responsibility. See licensing notice.
