Muse sounds: Where is marching percussion featured in your website and the demo "Snow falling?"

So I'm LOVING Muse sounds! But where is marching percussion? It's featured on the website and it's not available yet? Is it cancelled? Or is it not done yet? There are also some articulations mentioned that don't work like: Bartok pizz for strings, Flutter tongue for winds & Pres de la table in harp. And brass is lacking articulations Those are off topic but are something that could be improved. I assume that there is a lot to work on and that in the future, Muse sounds will become better and more finalized.
