I add tracks to sessions recorded with drum machines but in the DAW they are never on the money.
Realband you can adjust to so many decimal points but not Biab.
If you have different tempos in a song you create a midi click track and drag that in the DAW first.

I generated a drum track in RB @121.896bpm (Top track)
and one in Biab @122bpm (Bottom track), then dragged them into Pro Tools & Reaper set to 122bpm.
See pics below.

Can you generate up a short 32bar drum track in Biab @122bpm and upload it.
