OK, here are some setup pics for you. Took me a while because midi was not working!! So I tried a different file and that one worked with these settings. Can you send us your file - it may be file specific.

Nevertheless, it did work. This is newest BIAB 2022. I added the midi test file. Just download and remove the .txt portion of the name.
