MidiEvPtr TimeSign (long date, long num, long denom, long click, long quarterDef)
{
    MidiEvPtr e;

    if ( e = MidiNewEv(typeTimeSign))    /* Allocate a new event. Check not NIL */ 
    {
        Date(e) = date;                    
        MidiSetField(e, 0, num);
        MidiSetField(e, 1, denom);
        MidiSetField(e, 2, click);
        MidiSetField(e, 3, quarterDef);
    }
    return e;
