Custom control provides the Visual Basic programmer with a way to read and write MIDI files. Both 0 (single track) and 1 (multiple-track) formats are supported. Using the MIDIFILE control, you can modify existing MIDI files or create entirely new ones from scratch. You have complete control over and access to every type of MIDI message. You can easily insert, delete, and modify tracks and messages at any time. MIDIFILE has complete support for System Exclusive messages. This control is a storage structure for MIDI data. It has no recording or playback functions built in. It was designed following the Standard MIDI File 1.0 specification. What you do with the MIDI data that is loaded into this control is completely up to your programming. Several Visual Basic samples are provided to illustrate the use of MIDIFILE, including MIDIFILE Control - Actions, Message Text, Track Names, MessageNumber, and Tempo.
