AddMusicK is not mentioned here in this tutorial. In fact, what IS being mentioned is an outdated version of AMK, (called AddMusic 4 from what I can see).
Learn AMK from this tutorial instead.
Oh, and to answer your question, I'm pretty certain that ports made with AM4 will work with AMK.
EDIT: Actually, that tutorial I linked isn't a tutorial on how to use AMK, it's actually teaching how to port songs. Learning to use AMK is different from that. Read this
if that's what you wanted instead.
