Do you have the Windows version of BIAB? If so, go to Windows menu, MIDI Chord Detection. Play the notes on your MIDI keyboard and BIAB will tell you the chord, giving you up to four choices in case it’s ambiguous.

This is perhaps my favorite function in BIAB, and it appears most users don’t seem to know about it.

For your example, BIAB calls it F#m11. There's a lesser chance it is a B4/F#. I don't particularly like either name, but then it's just all ascending fourths with F# in the root. The point is, unless it simply cannot form a chord in any traditional way out of the notes you feed it, BIAB will give you some good suggestions. I use this all the time doing transcriptions.
