List of MIDI events

The following table summarizes the byte codes of the MIDI events. Short events are the ones with data stored in the Data member of the BRELS_MIDI_EVENT structure. Long events are the ones with data stored in variable size array with address stored in the lpData of the structure.

Event	Byte	Type	Description
Sequence number	0x00	Long	2 bytes informing the sequence number
Text	0x01	Long	General-purpose text
Copyright	0x02	Long	Copyright information
Track name	0x03	Long	Text corresponding to the name of a track
Instrument name	0x04	Long	Name of the instrument
Lyrics	0x05	Long	Lyrics text. Generally, each event corresponds to syllable of the song. Use a slash (either "\" or "/") to cause a line break.
Marker	0x06	Long	Marker text for something internal to the sequence (for example, "piano plays")
Cue point	0x07	Long	Hint text for something external to the sequence (for example, "curtains open")
Channel prefix	0x20	Long	1 byte to associate events to a channel
End of track	0x2F	Long	Marks the end of track. Contains no data
Tempo change	0x51	Long	3-byte value indicating the duration of a beat in microseconds
SMPTE offset	0x54	Long	Offset in SMPTE format of the start of an assynchronous track (not supported in the API)
Time signature	0x58	Long	Time signature of the sequence
Key signature	0x59	Long	Key signature of the sequence
Sequencer specific data	0x7F	Long	Sequencer specific data
Note off	0x8n	Short	Turns the sound of a note off in channel n. The first byte of data is the note and the second byte of data is the velocity. Both range from 0 to 127.
Note on	0x9n	Short	Turns the sound of a note on in channel n. The first byte of data is the note and the second byte of data is the velocity. Both range from 0 to 127.
Key aftertouch	0xAn	Short	Sets the pressure of a note in channel n. The first byte of data is the note and the second byte of data is the pressure. Both range from 0 to 127.
Controller change	0xBn	Short	Sets the value of a controller in channel n. The first byte of data is the controller number and the second byte of data is the controller value. Both range from 0 to 127.
Program change	0xCn	Short	Sets the instrument for channel n. The byte of data is the program number and ranges from 0 to 127.
Channel pressure	0xDn	Short	Sets the note pressure for channel n. The byte of data is the pressure value and ranges from 0 to 127.
Pitch change	0xEn	Short	Sets the relative pitch for channel n. The pitch is stored this way: 0xxxxxxx 0yyyyyyy, where the value is yyyyyyyxxxxxxx. It ranges from 0x0000 to 0x3FFF. Zero corresponds to -1.0 tone, 0x2000 means normal pitch and 0x3FFF means +1.0 tone.
System exclusive data	0xF0	Long	Specific to MIDI hardware devices. You should strip it from MIDI files
MTC Quarter Frame	0xF1	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
Song position pointer	0xF2	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
Song select	0xF3	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
Tune request	0xF6	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
MIDI Clock	0xF8	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
MIDI Start	0xFA	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
MIDI Continue	0xFB	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
MIDI Stop	0xFC	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
Active Sense	0xFE	Short	Specific to MIDI hardware devices. You should strip it from MIDI files
