Welcome
QUP Karaoke Engine
The Karaoke Operating Sytem
Professional karaoke hosting software for Windows, macOS, and Linux.
Manage rotations, playlists, singers, and live shows from one app. YOUR show YOUR rules. QUP can be configured to how YOU want things run.
Smart rotation
Fair singer ordering with graduated new singer preference, wait time locks, and bribe support.
Video + CDG playback
Play MP3+CDG, MP4, MKV with music video backgrounds, VU meters, and spectrum visualizers.
Cloud queuing
Singers scan a QR code and queue songs from their phone. No app install — works in any browser.

OBS recording
Automatically record each singer's performance via OBS WebSocket integration with scene switching and lower thirds.

AI creates karaoke tracks from any song — vocal separation and automatic lyrics transcription powered by Demucs and Whisper.
Music video backgrounds
Automatically downloads matching YouTube music videos to play behind CDG lyrics instead of a black screen.
Bribe system
