// Description:   A structure for handling MIDI input messages.
//                This class stores a time stamp plus up to 
//                four MIDI message bytes.  System Exclusive messages
//                are stored in a separate array in the MidiInPort
//                class, and their storage index is passed to the
//                user through a MIDI message for later extraction
//                of the full sysex message.
