File 'Folders' have been set up to separate the different song type categories. When adding new files to this area, add them to the appropriate folders. The *description* area underneath each file contains a short description that tells what is contained in each file. 'Zipped'(.zip) files can contain either Several MIDI (.mid) eseq (.fil) files. 1) If a 'zipped' file *description* mentions '.fil format', it contains eseq files. Else, it contains MIDI files. 2) If either a MIDI 'zipped' file *description* mentions '*Multi*', that file contains piano and other instruments within that file. (In the case of a 'zipped' file, either one more of the files within that file are 'multi- timbral' type files.) *These files may not play properly on older Disklaviers.* (At this time, January 2004, some of the 'zipped' files may contain a mixture of different musical categories. This may be sorted out at a future date.)
