Four sounds, four corners. Drag an orb toward a corner to colour it — overlap the middle for combinations. Pinch an orb smaller to hush it, spread it wider to make it louder. The edge sliders, each tinted to the orb it owns, set that voice's pitch. Slide two orbs so they overlap and they phase-mod each other — their glow swells and braids. Throw an orb off the edge and a fresh sound drops into the centre. Hit Rec, then drag an orb to capture a looping motion. Shake or hit ⟳ to re-roll.
