Built for how you already work
Dynamic Music States
Define states once (combat, exploration, stealth) and let transitions happen automatically as gameplay changes.
Smooth Track Transitions
Built-in fade system between song changes. Adjust fade duration or disable it entirely.
Smart BPM Tracking
Automatic BPM detection keeps every transition musically in-time, no manual tagging.
Drag & Drop
No code required. Assign tracks and states directly in the editor.
Fully Customizable with Blueprints
When you do want to go deeper, every hook is exposed to Blueprints.
Stems & Layer Control
Mix and mute individual instrument stems per state for deeper, more dynamic arrangements.
