  "description": "Backwards echo: every chunk of time is played back reversed during the next one, so notes swell in from nothing and cut off. Feedback flips the repeats back and forth. Fade sets how soft each chunk's edges are. Sync: 0 = free, 1..13 = 1/32 to 1 bar (chunks longer than 2 s are held at 2 s).",
