Rock'n Tread (Japan) — About this game
Rock’n Tread divides the performance between a chosen instrument and a drum part. The player selects guitar, bass or keyboard for the picking control, while a second action follows the drums. Instead of watching notes fall toward a fixed line, the judgement line moves across the notes. Matching both parts to that moving line makes the rhythm a matter of coordinating separate patterns within the same song.
