The MARKMIDI utility marks MIDI files as following the authoring guidelines for Windows MIDI files. The utility does not verify that the file is authored correctly, it only marks the file by adding a sequencer-specific meta-event to the first track chunk. MARKMIDI is an MS-DOS application with the following command syntax:
MARKMIDI src-filename dest-filename
If the MCI MIDI sequencer is used to play a MIDI file not marked with MARKMIDI, it will display a dialog informing the user that the file is not authored for Windows.
Note:
Do not use MARKMIDI to mark MIDI files unless the files were authored according to the guidelines presented in this chapter. If your application uses MIDI files not authored to these guidelines, the application must instruct users to install or create the proper maps using the MIDI Mapper Control Panel applet. For example, if your application uses MIDI files following the General MIDI channel recommendations, your users should create or install a General MIDI map for their synthesizers.
