Are you sure you would want to do that? Because running status by itself
would be just:

for(;;)
{
  thisByte = nextByte();

  if(thisByte & 0x80)
     runningStatus = thisByte;

  //... after which we get that:

  if(runningStatus == NOTE_ON || runningStatus == NOTE_OFF)
  {
    thisByte = nextByte();
    thisByte = nextByte();

    // note_on with zero velocity is note_off
    if(thisByte == 0 || runningStatus == NOTE_OFF)
      setLed(NOTE_OFF);
    else
      setLed(NOTE_ON);
  }
}
