01 / AttractClick the universe to place up to six gravity wells. Choose Orbit or Wander beneath the field for each well. Orbit keeps a circular path; Wander slowly moves between random destinations. Use the motion button to pause that well. Each orbit keeps its starting radius; dragging sets a new radius. A well placed exactly at the center stays there. Freeze pauses orbits too. Right-click to remove a nearby well, or use Clear gravity.
02 / DisturbSend a pulse to push particles outward. Enable Auto pulse and set its rate from 2 to 60 pulses per minute. Automatic pulses pause when frozen or when the tab is hidden. Freeze holds the physics while existing notes decay. Change worlds for a different starting character. Use Particles to add or remove particles live, from 8 to 48.
03 / ListenMusical mode adds a 40–160 BPM clock in 4/4. Structure controls the proportion of encounters snapped to eighth notes and mapped to the current chord. Four scale-derived progressions change chords every 2, 4, or 8 bars. The enabled drone follows these chords and the scale root; its manual chord and root return when Musical mode is off or Structure is zero. Pause listening restarts the phrase; Freeze stops encounters while the harmonic clock continues. Automatic pulses keep their separate rate.
Choose from nine synthesized encounter voices, including a guqin-inspired plucked string, Kalimba, Celesta, Singing Bowl, Warm Pad, and the original Orbital voice. These are synthesized voices. Changes apply to new notes; existing notes fade naturally. Encounters play notes from 13 scales. Enable the separate Chord Drone for a sustained warm chord underneath, with its own root, octave (−2 to +2), chord type, level, and eight sustained voices. Abyss, Rusted Cathedral, and Spectral Fog are dark ambient options. Encounter sound chance applies a 1–100% probability before the voice and rate limits; it does not affect the drone. The three Japanese options use common equal-tempered scale-book forms; traditional tunings vary. A voice limit keeps dense clusters musical. Delay, reverb, and brightness affect encounters only; the drone bypasses these effects. Delay sets echo spacing from 0 to 5 seconds; Reverb sets the reverb tail from 0 to 5 seconds. Zero turns the respective effect off; the instrument’s natural ring remains. Higher particles play higher notes; left and right become stereo position. Faster encounters play louder.
