LSD contains 490 unique audio tracks. Each area has its own five patterns that can be heard in any of seven different instrument sets which stay consistent throughout a day. The instrument set for a day is chosen at random each time a new day is started or when one of the opening clips is watched on the main menu screen, and the pattern for an area is randomly picked each time the player links to that area.
