RANDOM MIX
Every play, a brand-new song. A rhythm game with a composer inside: it writes the track live while you play it. The music never runs out.
Runs in your browser. Nothing to install, nothing tracked, works offline after the first load. What's in the full game
A rhythm game with an endless setlist
The song is generated
Press play and the drums, bass, chords and melody are synthesized on the spot.
50+ genres
Electronic, Hip-Hop & Bass, Rock & Metal, Chill & Jazz, Pop & Funk, Global and Cinematic, each with real BPM ranges, scales, swing and kits.
Five ways to play
JAM taps the notes, MIX remixes the stems, BATTLE goes head-to-head, AUTO plays hands-free, RADIO just listens.
The song becomes the game
Arcade modes replay your track as something else: a flap-flyer, a bullet hell where the drums are the guns, an asteroid run, a sonar maze, a melody you conduct.
A studio underneath
Drum grid, plain-language FX knobs, melody and instrument editors, live mixer, and a DJ booth that rerolls stems with a dice roll. You are the DJ and the producer here, no music knowledge needed.
