Thanks for the quick reply video track (is this the new Video Real Tracks feature? ah! ah!)

so, yes, I have downloaded patch 505 (yesterday) and I am ready to try the "button" bb cleanup exe (although I am a bit "unsure"..) but what will it be good for if the demo for the style is not to be found anywhere in my order BiaB 2018??

Next question: do you have this style yourself (-UrbFlk+) and if yes, does the demo works? As already said, it is not one, but quite a lot of other (MGUs with midi instruments)files which return a "not found" when trying to open the corresponding demo.

I remember that, in older BiaB versions, you had to have the style AND the demo song with exactly the same name in the bb file (reason why the bb file was sooo big...)
