In the FMOD Designer user manual under the Event Categories section, it states:
"The music category has a different, yet important purpose. Microsoft requires a title’s soundtrack be replaceable with the end-user’s own music files. The Xbox 360 allows end-users to import their own music using the Xbox 360 dashboard.
To comply with this requirement, all non-game related (soundtrack) music should be placed in the ‘music’ category. This allows the FMOD engine to automatically suspend the playback of audio in the music category and instead use the end-user supplied music tracks."
I could not find anything about how to follow this requirement in the FMOD Studio user manual, does similar functionality exist?
