A Midi time code quarter frame message with message type and value. These two fields are automatically assembled by MidiShare into one byte when the message is sent.
QuarterFrame events have 2 fields numbered from 0 to 1 :
0
- A message type from 0=Frame count LSB nibble to 7=Hours count MS nibble. (Field size : 1 byte)
1
- A count nibble from 0 to 15. (Field size : 1 byte)
Creates a QuarterFrame event and returns a pointer to the event or NIL if there is no more memory space.
MidiEvPtr QuarterFrame( long date, short type, short nibble, short port) { MidiEvPtr e; if ( e = MidiNewEv( typeQuarterFrame ) )/* Allocate a new event. Check not NIL */ { Date(e) = date; /* These information are common to all */ Port(e) = port; /* kind of events */ MidiSetField(e,0,type); /* Fields particular to QuarterFrame */ MidiSetField(e,1,nibble); } return e; }
