Aha. I think I know what is happening here. The tracks that render as stereo are coming out at the right level. The tracks that render as mono have a routing problem internal to BIAB that is doubling their level. I used _PROMSP which has 2 guitars that render mono, and those guitars are both double loud.

This is undoubtedly a bug. I'm sure it never worked like this before I have done dozens (maybe hundreds) of projects like this and would have noticed a doubling of the volume for sure.
