Use actionscript to trigger independant sound loop and reset

Is it possible, with flash to put different sounds triggered by a set of a buttons into a track and play this track in a loop ?

I want to make it so when you press for example buttons A, then B, then C, it will play the sounds A, B and C respectively in an infinite loop. So when you click A, B, C, D, E, it will play ABCDE.

EDIT: I succeeded ! I had to use arrays to do that. But now I would like that instead of putting the sounds automatically into the array at the beginning (red part), I want to be able to put by clicking on different buttons. It means if I click "A" first it will put the A into index 0, then B and put into index 1, then C and put into index 2, and so on. Also loop it indefinitely. How can ?

var musicTrack = new Array(); var aNote:a = new a(); var bNote:b = new b(); musicTrack.push(aNote); musicTrack.push(bNote); musicTrack.push(aNote); var musicChannel:SoundChannel; var currentSongIndex:int; function  onPlayBtnPressed() {   currentSongIndex = 0;   playSongFromIndex(currentSongIndex); } function playSongFromIndex(songIndex:int) {   musicChannel = musicTrack[songIndex].play();   musicChannel.addEventListener(Event.SOUND_COMPLETE, songFinished);   currentSongIndex++; } function songFinished(e:Event) {   if (currentSongIndex < musicTrack.length) {        playSongFromIndex(currentSongIndex);   } else  {        currentSongIndex=0;   } }

onPlayBtnPressed();
