So as many of you know, there are two ways of bringing in custom music to FT. The first and easiest way is to put custom music in the custom music directory and turn on the option to play this music in the game. This works, but ends up being terrible because you have zero control over which music files play at which times, etc. As far as I can tell (after spending countless hours searching tutorials and threads here on NMA), there is no way to customize any playback options using this method. The second way is to create a custom sound text file and import it into the level editor for each mission. This is fantastic, except for one problem: the importing process is an overwrite effect, which means all the original ambient sounds for that mission are overwritten. This is soul-crushing for me, as I deeply love the ambient sound design present in the game and do not wish to mess with it. Here is my question: is there any way, through hex editing the game or otherwise, to add custom music to specific missions without replacing/overwriting the original ambient sounds in that mission?
