"Also any additional research into replacing the videos or music and we will have an even sexier party for some fan modding." After reading that, I immediately started to search for things like "PlayStation 1 .SEQ specification". I am trying to build a MIDI to SEQ converter for LSD in C++. I know the basic .SEQ specs like pQES at the start of the file but I don't know what NoteOn, NoteOff etc. is in .SEQ format. Any help would be greatly appreciated.
