- File Type: $D7 (215)
- Auxiliary Type: All
-
- Full Name: MIDI file
- Short Name: MIDI data
-
- Written by: Matt Deatherage January 1990
-
- Files of this type and auxiliary type contain data for a Musical Instrument
- Digital Interface (MIDI) peripheral.
- _____________________________________________________________________________
-
- Files of type $D7 contain data that conforms to the MIDI standard as defined
- by the International MIDI Association. All data contained in files of this
- type must follow that standard.
-
- Although absolutely anything MIDI can fit in a standard MIDI file, developers
- may wish to store peripheral-specific or system-specific information in a file
- with a different auxiliary type for easier manipulation of the data. For
- example, if you were to write a program to control a Matthew IOP-1 Fabulo-
- Synth, you might wish to store the MIDI System Exclusive (SysEx) messages in a
- file with a distinctive auxiliary type. In doing so, not only could you find
- the information to control the Fabulo-Synth more quickly and conveniently, but
- other applications could also know not to even waste time presenting the file
- to their users for use on other peripherals. This capability is obviously not
- desirable to all creators of MIDI applications; however, Apple assigns
- auxiliary types to allow you the choice.
-
- The following auxiliary type assignments are current for this file type as of
- the publication date of this Note:

- The auxiliary types for this file type are reserved; any not listed in this
- Note or About File Type Notes must be assigned by Apple Computer, Inc. Using
- any file type or auxiliary type not assigned may result in conflicting
- identification of files by totally unrelated programs. To obtain an auxiliary
- type assignment in this file type, see About File Type Notes.
