I just wish the project file was an xml file, because that would mean that all information (including MIDI) could be extracted.
It would also allow for using XSL transform sheets to clean up, reorganise or print out one or more projects. Of course, a badly designed one could thoroughly mangle your projects, which is possibly why SB locks down the internal format from over-ambitious experimenter’s eyes.
Mind you, xml files can be made to have cryptic structures as well.
