I´ve been playing around a bit with the excellent sound framework made by Kei Mesuda called SiON

This example uses SiON in its simplest way, playing two jazzy chords when the user clicks the stage

Get the swc / source:

To get started you need to head over to SiON Spark

Example 1 – Jazz SiON non standard voice:

Click stage for sound:

// Sample for event trigger
package
{
	import flash.display.*;
	import flash.events.*;
	import org.si.sion.*;
	import org.si.sion.SiONData;
	import org.si.sion.SiONVoice;
	import org.si.sion.utils.SiONPresetVoice;

	public class Sion extends Sprite
	{
		public var composer:SiONDriver = new SiONDriver();
		public var melody:SiONData;
		public var presets:SiONPresetVoice;
		public var voice:SiONVoice;

		private var _on:Boolean = false;

		function Sion()
		{
			stage.addEventListener(MouseEvent.CLICK, playSound);
		}

		private function playSound(e:MouseEvent):void
		{
			var sheet:String;

			if (! _on)
			{
				sheet = "t100;";
				sheet +=  "%3@8 [b+2]1;";
				sheet +=  "%3@8 [f+2]1;";
				sheet +=  "%3@8 [c+2]1;";
				sheet +=  "%3@8 [g2]1;";
				sheet +=  "%3@8 [o2a2]1;";
			}
			else
			{
				sheet = "t100;";
				sheet +=  "%3@8 t100 [b2]1;";
				sheet +=  "%3@8 [e2]1;";
				sheet +=  "%3@8 [c+2]1;";
				sheet +=  "%3@8 [f+2]1;";
				sheet +=  "%3@8 [o3d2]1;";
			}

			presets = new SiONPresetVoice();;
			voice = presets['valsound.bells2'];

			melody = composer.compile(sheet);

			composer.play();
			composer.sequenceOn(melody, voice, 0, 0, 1, 1);

			_on = ! _on;
		}
	}
}
