Make sure that you name the instance of the button on the stage.

Drag out more of the buttons until you have one for each sound. Name them appropriately mine were named

stairPlus6_btn stairPlus5_btn stairPlus4_btn stairPlus3_btn stairPlus2_btn stairPlus1_btn stairPlus0_btn stairMinus1_btn stairMinus2_btn stairMinus3_btn stairMinus4_btn stairMinus5_btn stairMinus6_btn

once you have all the named instances on stage it's time for some code.

add the folling to load the sound from the library

 
//Load sound from library
soundPlus0= new Sound();
soundPlus0.attachSound("ploor");

Now add the code to play the sound when the button is pressed

 
//Play sound when named button is released
stairPlus0_btn.onRelease = function() {
    soundPlus0.start(0,1); 
}

note: You can alos use onRollOver instead of onRelease if you want to make a lazier paino

Test then repeat with the rest of the buttons ie

 
//Load sound from library
soundPlus1 = new Sound();
soundPlus1.attachSound("ploorPlus1");
 
//Play sound when named button is released
stairPlus1_btn.onRelease = function() {
    soundPlus1.start(0,1); 
}

lastly here is some code that will play a specific 'stair' with the computer keyboard

 
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
   trace("The ASCII code for the last key typed is: "+Key.getAscii());
   if(Key.getAscii() == "113") //q key
   {
	   Minus6.start(0,1);
   }
   if(Key.getAscii() == "119") //w key
   {
	   Minus5.start(0,1);
   }
   if(Key.getAscii() == "101") //e key
   {
	   Minus4.start(0,1);
   }
   if(Key.getAscii() == "114") //r key
   {
	   Minus3.start(0,1);
   }
   if(Key.getAscii() == "116") //t key
   {
	   Minus2.start(0,1);
   }
   if(Key.getAscii() == "121") //y key
   {
	   Minus1.start(0,1);
   }
   if(Key.getAscii() == "117") //u key
   {
	   Plus0.start(0,1);
   }
   if(Key.getAscii() == "105") //i key
   {
	   Plus1.start(0,1);
   }
   if(Key.getAscii() == "111") //o key
   {
	   Plus2.start(0,1);
   }
   if(Key.getAscii() == "112") //p key
   {
	   Plus3.start(0,1);
   }
   if(Key.getAscii() == "91") //[ key
   {
	   Plus4.start(0,1);
   }
    if(Key.getAscii() == "93") //] key
   {
	   Plus5.start(0,1);
   }
    if(Key.getAscii() == "92") //\ key
   {
	   Plus6.start(0,1);
   }
};
 
Key.addListener(keyListener);

If you like you can also draw a larger box in the hit frame of the button to allow the button to be pressed easier.
