I'm hoping someone can tell me if what I'm trying to do is possible (or not). I've got a MIDI soft synth, called Winlive Synth Driver, which is selectable as a MIDI Output device in BIAB. I can get it to play MIDI sounds when I am not using BIAB but not when BIAB is open. Here's my setup:

*BIAB 2020 for Windows
*Windows 10
*Input - External MIDI controller keyboard - via USB
*Two soundcards - a built in one from NVIDIA and an external one plugged in via a USB port. I normally use the one in the USB port.
*Audio Driver type is ASIO, using ASIO4All v2.14
*MIDI Output Driver has "Winlive Synth Driver WSD" selected from the list box.
*The boxes for "Use VSTI/Dxi Synth" and "Route MIDI Thru to MIDI Driver" are both checked
*The DxiSynth Settings shows CoyoteWT, but I don't use it
*Audio Settings box is set to "ASIO [Always]"

This setup works just fine for recording MIDI in from the keyboard using MIDI sounds, or using a VSTi plugin like Sforzando, or any of several others. If I choose any MIDI instruments, however, no matter what configuration I select, it uses the built in Microsoft GS Wavetable Synth sounds. If I try to select the Winlive Synth driver, there are no sounds from the MIDI thru, or from using the keys in the Pianos tab from the mixer for any MIDI instrument, or from the MIDI track within BIAB.

What I'm guessing is that the ASIO configuration is incompatible with using this MIDI out driver. I know that when ASIO is loaded, it controls the sound card output and no other program can play sounds through the card, and that is by design. I just thought that if the system could play the Microsoft MIDI sounds, it should be able to play sounds generated from another MIDI driver.

I've really spent a good chunk of time and effort on this, so if there's an easy answer, then I'll make a point to dig deeper next time.
