if (cc != oldValue[i]) help needed *SOLVED*

Hey!
I'm putting together my first MIDI controller in Arduino and the CC it's sending out is a little too unmanaged. I want to take "if (cc != oldValue*" and change it a little to mean this:*
If the new CC is different to but at least 3 away from the old value, send the CC.
Thanks to anyone that can help :slight_smile:

Maybe this can be of some help:

void DoCC( int new_CC ){

  static int prev_CC = 0;

  if( new_CC >= ( prev_CC + 3 ) || new_CC <= ( prev_CC - 3 ) ){
    
    prev_CC = new_CC;
    //Send CC
  }
}

const int deadZone = 3;
if ((newValue+deadzone) < oldValue || newValue > (oldValue+deadZone)) {
}

Thanks, that's perfect and it solved the problem perfectly :slight_smile:

The deadZone needs to be 2 otherwise the 'at least 3 away' becomes 'at least 4 away'.
