Yeah, I got a MODX6!

Now I have to figure out what to do with it. I have no skills in playing or composing :D.
Watching yamahas' youtube helped my to make my purchase, so thanks Blake and Dom.

I can make sound out of it, which entertains me for hours, but what would be a good way to start/continue my journey to modx?
I suppose mastering the menus would be one! :p
