Something is seriously messed up. I have been using a workflow for years where I render individual tracks to WAV using the File -> Export Song as Audio File button. From there, I take the tracks into a DAW. I have done this workflow with nearly 100 songs in recent years. I have had no problems recently until about 3 months ago.

I am using BIAB 2021 with Windows 10. Now, in most cases when I try to render the tracks, the bass track comes out completely silent, and usually the guitar track as well. Piano and Drums always play normally.

If I render a full song mix, all the instruments play normally. And if I drag the bass or guitar into the little box that has WAV, MP3, MID, etc., it renders properly. It is only when using the File -> Export Song as Audio File button that these tracks come out silent.

I have completely reinstalled BIAB and all the styles. No good.

It seems to fail on multiple style files -- it is not just one bad style.

I tried substituting a different bass patch and it was still silent.

I created a new song file completely from scratch and it is still silent.

I don't know exactly when this went wrong. I worked on a bunch of songs from January through July of 2021. The past few months I was diverted onto some other work. I just returned to a song I had started in July and found I had generated silent tracks for bass and guitar, and never went any farther.

Since that time, I may have applied two patches to BIAB and am currently running the latest patch. There have been lots of Windows patches in that time.

Anybody have any ideas what might be going wrong here? Here is a test file that exhibits the problem on my system:
