There is no democracy at the Casio Facebook group https://www.facebook.com/groups/Casio.MZ.X/
I posted "still no videos" and after 1 a 2 minutes my message was deleted and when I asked why my new post must be approved by admin. I mentioned this on the Casio forum and guess what , yes also deleted. So I think Nigel was right. The mz x doesn't sound that good otherwise why no promotion video like korg and Yamaha does. Yes there is one video but that doesn't show how the mz x really sound.
