Update:

Not sure if this is good news or bad news.
I still have BIAB 2020 installed on a laptop, so I tried it there
AND IT WORKS!

The MIDI/Audio Driver set up window is IDENTICAL to what is shown above,
regarding the Input portion (Output is Coyote, not TTS-1).

I know that will "muddy the waters", but I'm glad to find out my memory isn't failing me! LOL

Still need help.
Any other ideas?
Thanks!
