I'm creating a piano type player and want to load different audio files at different times, then have the others stop. I have separate players player at different mouse coordinates, but they all continue to play. How can I achieve this?! Below is my code for reference:

//charlie silverman
//march 2010

float bright0 = 255;
float bright1 = 255;
float bright2 = 255;
float bright3 = 255;
float bright4 = 255;
float bright5 = 255;
float bright6 = 255;
float bright7 = 255;
float bright8 = 255;
float bright9 = 255;
float bright10 = 255;
float bright11 = 255;
float bright12 = 255;
float bright13 = 255;
float bright14 = 255;
float bright15 = 255;
float bright16 = 255;

import ddf.minim.*;
AudioPlayer player1;
AudioPlayer player2;
Minim minim;

void setup() {
 size(500,200);
 strokeWeight(2.0);
 minim = new Minim(this);
 player1=minim.loadFile("03 Barfly.mp3", 2048);
 player2=minim.loadFile("01 Homesick.mp3", 2048);

}

void draw() {
 // Draw the background
 background(255);

 // Depending on the mouse location, a
 // different rectangle is set to brightness 255
 if (mouseX>0 && mouseX < 50 && mouseY > 100) {
   bright0 = 0;
   player2.play();
 }
 else if (mouseX>50 && mouseX < 100 && mouseY > 100) {
