Play multiple audio files at once visual basic

I'm making a virtual piano in Visual Basic, Visual Studio 2013. However I found a problem. I've been using the function "My.Computer.Audio.Play(My.Resources.C, AudioPlayMode.Background)" to play a certain note, but then if I want to play another note it just cuts the sound of the previous, when what I wanted was to play the two notes at the same time.

Isn't there any function that allows to play an entire audio file until the end?

Thanks in advance
