The BMS file type is a sequenced music format used in many games. For the cave music in Pikmin 2 however, it is specially-formatted. It mainly contains many short snippets of musical information to be randomized. | The BMS file type is a sequenced music format used in many games.

Edit your song in the trackMap files in either <code>/user/Totaka</code> or <code>/user/Wakai</code>, and set how many instruments will be in each mix. It goes in order from: Main Mix, Task (event), Treasure (otakara), Enemy near (kehai), Combat mix, and Spiderwort mix (ground). Although you cannot find Spiderworts underground, you will have to sacrifice at least one track for that mix. You cannot set any of the mixes to have 0 instruments in them. |
