Midi filtertering of stop start messages

I wonder if I could ask you both once again for your help?

I want to send a midi note to a module to indicate audibly the tempo along with the LED. I have tried adding this but I'm afraid the coding won't compile correctly.

   else if ((data == midi_clock) && (play_flag == 1)) {
      if (clk / 2) digitalWrite(tempoled, LOW); //digitalWrite(tempoled, LOW);  // percentage of lit time
      MIDI.sendNoteOn(60, 127, 1);
      else digitalWrite(tempoled, HIGH); //digitalWrite(tempoled, HIGH);
      digitalWrite(tempoled, HIGH);
      MIDI.sendNoteOn(60, 0, 1);
      Serial.write(midi_clock); // send midi clock to out... Provides tempo!
      clk++;
      clk = clk % 24;
    }
  }
}

What do I need to alter in the code please?
