Two sounds to start, 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 up off the top and it falls back down as a different sound; throw it down off the bottom and it just leaves. Hit + to add an orb (up to four). Hit Rec, then drag an orb to capture a looping motion. Shake or hit ⟳ to re-roll.
