Hey there! Goldenboy came up with genius solution to some of the problems, and basically a solution for "chanting" sound. I am not 100% sure I fully know how, but he's got it right. He's working on a full conversion to german language, and meanwhile, I'm just trying to bring back old classics. Here's the solution mail :

I've been really REEEALLY busy (and not only because of GTA V as you can see in the mail), I'm gonna be in England for 1 month (basically Student Exchange) and I've got alot of things to do before leaving. So I can't promise anything but I'll look back into this soon. Have a nice day!
