Sound only plays once, why?

  call rewind() before play(). the playhead needs to be pushed back to the start after you played it. rewind does this.

  and you can use sound.trigger() or you could when I last checked

  @mschi: The problem with rewind() ist that the sound keeps playing and overlays endless times so you only get to hear a mess. I would like to get the sound playing always one time when you move above the shape. Any ideas? :)
  And trigger() does not seem to work anymore?

  try pause(); rewind(); play();

  maybe just calling play(0); also does the job.

  Unfortounately this doesn't change anything. ^^
  I really don't know what's wrong here, that's the actual code:
  

  import ddf.minim.*;
  
  Minim minim;
  AudioPlayer Snare, Bass, Cymbal_Crash;
  
  
  void setup()
  {
    size(500, 250);
  
    minim = new Minim(this);
    Snare = minim.loadFile("Snare_Hit.wav");
    Bass = minim.loadFile("Bass_Drum.wav");
    Cymbal_Crash = minim.loadFile("Cymbal_Crash.wav");
  
  }
  
  void draw()
  {
    background(255);
  
    ellipse(120.5, 125, 47, 47);
    rect(250, 125, 47, 47);
  
  
    //Snare_Hit = Circle
    noFill();
    float mix1 = Snare.mix.level();
    println(mix1);
    float grau1 = map(mix1, 0, 0.5, 0, 255);
  
    stroke(grau1);
    ellipse(120.5, 125, mix1*200, mix1*200);
  
  
    //Bass_Drum = Rect
    noFill();
    float mix2 = Bass.mix.level();
    println(mix2);
    float grau2 = map(mix2, 0, 0.5, 0, 255);
  
    stroke(grau2);
    rectMode(CENTER);
    rect(250, 125, mix2*200, mix2*200);
  
  
    //Cymbal_Crash = Triangle
    noFill();
    float mix3 = Cymbal_Crash.mix.level();
    println(mix3);
    float grau3 = map(mix3, 0, 0.5, 0, 255);
  
    stroke(grau3);
    triangle(356.866, 148, 383.135, 102.5, 409.405, 148);
  
  
  
      if (mouseX > 97+8 && mouseX < 144+8 && mouseY > 101.5+8 && mouseY < 148.5+8)
      {
        Snare.pause();
        Snare.rewind();
        Snare.play();
      }
  
      if (mouseX > 225 && mouseX < 275 && mouseY > 100 && mouseY < 150)
      {
        Bass.pause();
        Bass.rewind();
        Bass.play();
      }
  
      if (mouseX > 356 && mouseX < 411 && mouseY > 101.5 && mouseY < 149)
      {
        Cymbal_Crash.pause();
        Cymbal_Crash.rewind();
        Cymbal_Crash.play();
       }
  
  }
  

  And that's a short demonstration of the repetitive sound:

  In setup just add player.loop();

  take your play trigger code out of draw() and insert it into a mousePressed function:

  void mousePressed() {
      if (mouseX > 97+8 && mouseX < 144+8 && mouseY > 101.5+8 && mouseY < 148.5+8)
      {
        Snare.pause();
        Snare.rewind();
        Snare.play();
      }
  
      if (mouseX > 225 && mouseX < 275 && mouseY > 100 && mouseY < 150)
      {
        Bass.pause();
        Bass.rewind();
        Bass.play();
      }
  
      if (mouseX > 356 && mouseX < 411 && mouseY > 101.5 && mouseY < 149)
      {
        Cymbal_Crash.pause();
        Cymbal_Crash.rewind();
        Cymbal_Crash.play();
       }
  }

  @mschi: Wow, that's really cool and does the job for me, thank you very much! :)
  Do you also know how to scale a triangle with it's ankerpoint centered? ^^

  you basically have to do something like that:

  draw(){
  pushMatrix();
    // define position where circle is supposed to sit
    translate(50, 50);
  
    // big is a boolean that is true as long as the circle is supposed to be big
    // you have to set it to true/false at some place
    if(big)scale(2.0);
    else scale(1.0);
  
    ellipseMode(CENTER);
    ellipse(0, 0, 40,40);
  popMatrix();
  
  pushMatrix();
  ... do the same with rect
  popMatrix();
  
  pushMatrix();
  ... do the same with triangle
  popMatrix();
  }

  yes .trigger works and it would be way easier. This is a processing example that I changed a little:

  import ddf.minim.*;
  
  Minim minim;
  AudioSample kick;
  AudioSample snare;
  
  void setup() {
    size(512, 200, P3D);
    minim = new Minim(this);
    kick = minim.loadSample( "kick.mp3", 512);
    snare = minim.loadSample("snare.mp3", 512);
  }
  
  void draw() {
    background(0);
    stroke(255);
    for (int i = 0; i < kick.bufferSize() - 1; i++) {
      float x1 = map(i, 0, kick.bufferSize(), 0, width);
      float x2 = map(i+1, 0, kick.bufferSize(), 0, width);
      line(x1, 50 - kick.mix.get(i)*50, x2, 50 - kick.mix.get(i+1)*50);
      line(x1, 150 - snare.mix.get(i)*50, x2, 150 - snare.mix.get(i+1)*50);
    }
  }
  
  void mousePressed() {
    if (mouseX < width/2) snare.trigger();
    if (mouseY > width/2) kick.trigger();
  }

  Hello, I think I know what the mousePressed is suppose to do but it is being used with width instead of height which does not seem to have the proper effect. I changed it to this and it seems to work better. Cool little mini drum pad BTW. DJ xSUBn ({-_-})

  void mousePressed() {
    if (mouseY < height/2) { snare.trigger(); } else { kick.trigger(); }
  }
