Dear colleagues,
a greeting to all who have given me to my problem tips ...

I ran BiaB as an administrator and was able to easily play various songs from the bb directory. Then I loaded my self-created song, which is the problem. It's just a raw sketch of a new song. I would like to continue working on it, but as soon as the song is to be played, I try different Realtracks, which are known to be rendered before playing, immediately comes from the UA-101, the noise and BiaB the error message that I have already sent you in part. It seems only with this song! Should I send you the file? So it could be tried, if the file, my song-sketch, runs without problems.
My ROLAND UA-101 (audio / midi interface) with Windows 10 driver works well with CUBASE 9.5 PRO.

I have the same BiaB / Roland UA-101 problem on my other PC with Windows 7. I switched to Windows 10 and a new computer only a few days ago. I worked with the Windows 7 machine and BiaB for almost 8 years and never had a problem.

I've just received the tip from Kent - PG Music, I'll try it right now ---
