The MIDI files that are found on the World Wide Web are generally PC formatted files. These files often have a .MID extension. These files can be opened in Digital Performer if you select "Show all Readable files" from Digital Performer's open file window. These files can also be dragged from the Finder, or Sherlock into any of Digital Performer's track windows or into the Chunks window. You may need to run these files thru "Midi File Converter" for them to show up... Midi File Converter is located in the Performer Folder>Extras folder.
