Music in Mods

How do you change the music in Mods?
I've looked all over for a tutorial, but i cant find one so i thought i'd ask the people that know best.
Thank you for any help.

I think it's something silly like re-naming a bik file ext, but knowing me I'm probably wrong.

The three main music samples live in your /GP4/Sounds folder. They are called tk1.st1, tk2.sk1 and tk3.st1.

To edit them, you need GP4 Sound.exe and some new music in .wav format.

Convert one of the existing .st1 files back to a .wav first to see exactly which format you need your new .wavs to be in (because not all possible .wav options are supported).

Thank you for suggestions, i will look into it and see what i come up with.

If you use CSM just insert 1 to 3 .mp3 files in the "Data \ Music" directory of your mods.
The program will convert the files to .st1 format as soon as you launch the mod!

Thank you very much all you guys.
