  dms91, I am doing a similar thing with the following code:

  // Create and load image & sound matricies
  // ---------------------------------------
  int i = 0;
  
  for (String animal : animalList) {
  imgName = "data/" + animal + ".jpg";
  images[i] = requestImage(imgName);
  //images[i].resize(width,height);
  sound = "data/" + animal + ".mp3";
  animalSound[i] = sound;
  aName = "data/say-" + animal + ".mp3";
  animalName[i] = aName;
  aList += animal.charAt(0);
  i ++;
  

  }

  and playing the sounds after a key press with this code:

  void keyPressed(){
  if (player.isPlaying()){player.pause();}
  
  col = color(random(255), random(255),random(255));
  background(col);
  int key1 = aList.indexOf(key);
  if (key1 == -1) {
  background(col);
  fill(#18ED76);
  text(Character.toUpperCase(key), width/2, height/2);
  return; }
  
  playName(key1);
  
  showImage(key1);
  
  playSound(key1);
  
  char letter = aList.charAt(key1);
  showLetter(letter, animalList.get(key1));
  }
  
  playName(key1);
  
  showImage(key1);
  
  playSound(key1);
  
  char letter = aList.charAt(key1);
  showLetter(letter, animalList.get(key1));
  }
  
  void playSound(int k) {
  player = minim.loadFile(animalSound[k]);
  player.play();
  }
  
  void playName(int k) {
  player = minim.loadFile(animalName[k]);
  player.play();
  }
  
  void showLetter(char letter, String animal) {
  col = color(random(255), random(255),random(255));
  fill(col);
  letter = Character.toUpperCase(letter);
  textAlign(LEFT);
  text(letter, 50, 110);
  textAlign(CENTER);
  text(animal, width/2 - (animal.length()/2), height -75);
  textAlign(RIGHT);
  text(letter, width-100, height-50);
  }
  
  void showImage(int k) {
  mage(images[k], width/2, height/2, 700,600);
  }
  

  The image and sound files are in the data folder. The trouble I have with Minim is that if I press keys too quickly the player quits with a null exception.

  Hope this helps.
