Jim’s explanation about ASIO is exactly right and well stated.

ASIO drivers that support multiple devices are beginning to be used more frequently, but using MME for BIAB is generally a safe choice.

I’ve noticed that the timing between MIDI and audio tracks in BIAB needs to be adjusted when I change the audio driver, so I tend not to make that change unless I have a very good reason, like recording a keyboard in BIAB in real time. And since I’m not a keyboard player, that’s really rare!
