I am having trouble getting the noteOn function of the proMidi Library to return multiple notes when a chord is played.

I have built a sketch using proMidi.

the value of the variable note inside the noteOn(); function is used to define an objects appearance:

void noteOn (Note note, int device, int channel) {
  for (int i=0; i < bubble.length; i++) {
      if (bubble[i].build == false) {
          bubble[i].button = true;
          bubble[i].noteToCheck = note;
          break;
      }
  }
}

The sketch works fine with one exception:

  if a chord is played (multiple notes at once) only one note variable is returned.

this seems to be because of the way the function is defined:

  void noteOn (Note note, int device, int channel) {

it has an Input of a single note rather than an Array of notes, this is peculiar because when the note is sent to the midi output via sendNote(); all played notes are heard:

  midiOut.sendNote(note);

How can I get the noteOn(); function to receive all played notes in a single frame, and/or get my objects to react to all notes played at once?

Can I get the noteOn function to receive an input of an Array of notes?

  void noteOn (Note [] note, int device, int channel) {
