Where the voice lives: its register, from low to high. Turn it and the voice migrates.
How far the notes stray from where Attraction pulls them, and how much their durations vary.
Memory: how often the voice returns to a figure it already played instead of improvising. At 100% it unlocks Pitch and Rhythm length.
How often the voice speaks, from sparse to dense. The denser, the shorter the notes.
Depth: reverb and echo. How far each note reaches and how long it lingers.
How many notes and how many durations the repeated figure has. Different numbers change it at every cycle.
