MIDI Packet

The MIDI packet structure describes the data passed by note allocation calls. It is defined by the MusicMIDIPacket data type.



 
struct MusicMIDIPacket {

    unsigned short          length;

    unsigned long           reserved;           

    UInt8                   data[249];

};

typedef struct MusicMIDIPacket MusicMIDIPacket;

length: The length of the data in the packet.
reserved: This field contains zero or one of the music packet status constants. See "Music Packet Status" [link] .
data[249 ]: The MIDI data.

This is the count of data bytes only, unlike MIDI Manager or OMS packets.
