  "description": "An echo that locks to the tempo: pick the note value (a quarter, a dotted eighth, an eighth or an eighth-note triplet) instead of milliseconds, and the repeats land in time whatever the song's speed. Style chooses crisp digital repeats, dark analog ones, or repeats that bounce between the sides.",
