Custom Music

New in GLE-V2, the ability to alter an AST's Track Controls! This is hardcoded in the vanilla game (called cBgmSettingInfo), but has now been delegated to a BCSV.

TrackControl.bcsv

A new BCSV file located in AudioRes/BgmParam.arc, TrackControl.bcsv controls 2 settings for each song in the list:

• Mute Type
• Change Type

Mute Type

There are a total of 29 types. Most are unknown.

Change Type

The GLE has 8 Change Types, and these define how the Mute Type is activated.

ID	Name	Description
0	None	Changes can only be done via hardcoded events.
1	Yoshi Drums	Activates Yoshi drums when you hop on Yoshi.
2	Water Music	Activates underwater music when the camera goes underwater. Also supports Yoshi drums, however they cannot be played at the same time as the underwater music. The code also supports activating via riding a koopa shell underwater (like SMG's Beach Bowl), but I was unable to get this working.
3	Slowdown Switch	Activates slowdown music when a slowdown switch is triggered. Also supports Yoshi drums, however, the drums will be deactivated during a slowdown.
4	Dash Yoshi	Activates Yoshi drums when you hop on Yoshi. Also speeds up the song when using a Dash Pepper. *Requires a sequenced track in order to work.
5	Fire Flower	Activates when you have a fire flower. Only used for Squizzard's boss theme. *Requires a sequenced track in order to work.
6	Bowser Meteors	Activates when Bowser's Meteors are punched out of the ground and float in the air.
7	Worldmap (Unused)	Does not activate. Only here for future proofing the system, as I may repurpose this for something else in the future.

Common setups

Note: As of writing this, there is currently no possible way to create custom BMS files.

Yoshi Drums

There are two types of Yoshi drums that you can make: Sequenced and Streamed.

Sequenced Drums

Currently, it is not possible to make custom BMS files. For the sake of completion, this guide pretends that it is possible. If you are looking to actually make some custom Yoshi drums, please look into Streamed Yoshi Drums

To make sequenced Yoshi Drums, follow the following steps: (Remember, these are only theoretical steps)

1. Make a custom BMS with the Yoshi Drums on Track 15.
2. YAZ0 encode the BMS, and insert it into AudioRes/Seqs/JaiSeq.arc using WiiExplorer. Make sure the File Properties inside the RARC file are set correctly. To do this, check "IsCompressed" and "IsCompressedYaz0" (Or click on the button labeled "Auto"). Also ensure the File ID is the same as the file you replaced (if you didn't replace a file, make sure this ID is the same ID that the SMR.aaf file expects.)

Note: WiiExplorer is the only program that can successfully edit JaiSeq.arc. The use of other programs will cause severe audio issues.

3. Inside TrackControl.bcsv, set your song's MuteType to either 8 or 16, and the ChangeType to 1, 2, or 3 (depending on what behavior you want).
4. Setup the Multi BGM Info to sync the AST loop points to the BMS bars.
5. Place Yoshi into the level.

In theory, your Yoshi drums should now play whenever you jump on Yoshi. Again, this is purely theoretical, as BMS files cannot be created at this time.

Streamed Drums

To make streamed Yoshi Drums, follow the following steps:

1. Make a custom AST file with Yoshi drums on the second AST channel (Wav Channel 3 [Left Ear] and Wav Channel 4 [Right ear])
2. Inside TrackControl.bcsv, set your song's MuteType to 17, and the ChangeType to 1.
3. Place Yoshi into the level.

Your Yoshi drums should now play whenever you jump on Yoshi.

Slowdown Switch

To make Slowdown music, follow the following steps:

1. Make a custom AST file with Yoshi drums on the second AST channel (Wav Channel 3 [Left Ear] and Wav Channel 4 [Right ear])
2. Inside TrackControl.bcsv, set your song's MuteType to 6, and the ChangeType to 3.
3. Place a HipDropTimerSwitch into the level, and configure it for the Slowdown mechanic.

Your Slowdown music should now play for as long as the switch is activated.

BgmChangeArea

This setup is for galaxies like Freezeflame and Shiverburn where the music changes when you reach certain points in the galaxy. Those "certain points" are handled by BgmChangeAreas. To setup the ast, follow these steps:

1. Make a custom AST file with Yoshi drums on the second AST channel (Wav Channel 3 [Left Ear] and Wav Channel 4 [Right ear])
2. Inside TrackControl.bcsv, set your song's MuteType to 5, and the ChangeType to 0.
3. Inside StageBgmInfo.bcsv (/AudioRes/Info/StageBgmInfo.arc), set the song's ChangeBgmState%d to 2 for the galaxy using the music. (Very likely that ChangeBgmStage0 is the field you're looking for)
4. Place down some BgmChangeAreas and set them up the same as they are in Shiverburn Galaxy (KachikochiLavaGalaxy).

Your music should now change channels when you enter the area. If not, try changing the settings on the BgmChangeArea.
