HI George
Yes I get the same results ,
I notice that the audio track does not appear in the video render screen where you select what you want to render. So I guess that is why .
All other parts tracks are available even if they don’t contain video.
As in the case if you just substituted video drums for non video drums in any style if it fits.
You can have a video of the drummer playing but you still hear all the non video parts from the original style, in the finished video.
But like you I see no way of including the audio track.
Mike
