Piggybacking off a request from Meteormancer early last month, I am looking for info on the method to add new music IDs to the game, with the intention of adding new tracks to certain fields/battles with Makou Reactor. I have accumulated a list of the already existing IDs:

My hope is that once the process of adding new IDs is clear and documented here for others, some research can begin on how to implement a Remake-style cross-fade of the games music, for a somewhat smooth blend of field music into battle music. I could be wrong on how this functions, but my understanding is that there is a "timestamp" value in the games field music that the engine hooks/remembers before beginning the screen whirl into battle music, which it then returns to upon battle completion. I want to utilize this value to begin battle music playback from the same "timestamp", instead of starting each battle track from the beginning. Counting on Qhimm's many and varied brain trust to offer me info on the viability and implementation of this type of music system. Thanks, all.
