I think that is a BIAB limitation! I run two keyboards over USB with Win 11, no problems. Also run a midi controller via USB at the same time. As well as my midi in and out via the MOTU Audio Express. So I never have issues with MIDI routing except back in the day when I tried to run Helicon Voicelive and use the Voicelive Editor software with BIAB.
