A major generator update and a new interface. Notes now land on the rhythm: tempo is detected to a hundredth of a BPM, and on live recordings the grid follows the performance. Maps follow the song's structure: a repeated chorus plays with the same patterns, a new section brings new movement. Horizontal swings, rotations and wide play are in. Difficulty levels were retuned so that density, hand movement and double hits match hand-made maps — Expert now plays like an Expert. Loud parts of a song get more notes, quiet ones fewer. Maps are easier to rework in an editor: on tracks with a steady tempo, notes sit on the grid lines and the editor's measures match the song's bars. You can watch the finished map right in the app, with notes flying to the music and the song's sections below. Regenerate just one part of a song, pick a style (Balanced, Classic, Flow, Fitness), choose what to follow (drums, or vocals and melody) and set note speed per difficulty.
