Oddly some people have version 16 of Music Maker. Version 15 is the latest I see on the sales sight. There is even a UTube advertisement for version 16 as well as people posting songs they have done and tutorials.
You either move to Europe, or wait like everyone else.
MMM-16 is only available in Europe at the moment, but probably not for long. That is why MAGIX has started a big push to sell off their stock of MM-15.
The question I have is....since MM-15 is so buggy...why would you be in such a rush to buy MM-16???
Personally, I'd wait to see if it is actually an improvement or more of the same @#%& relabeled.
