80% well that's a no brainer then.
There's another reason for direct play, if Biab just loads the RT data from the selected style then plays back the inputted chord direct from the RT's on the hard drive.
Else as mention you could generate up up tracks in the key/chords you want to play in and Biab on chord change will go to those bars with smooth seek like Reaper. The smooth seek will also allow the Conductor to work.

I only need (literally) the same thing those casio keyboards do, where I can play a C maj chord, and the accompaniment instead switches to C maj. Then when I play an Fmaj chord (even in 2nd inversion) it will switch to that.

I'm planning to use this software for echo playing of rhythms and melodic passages to teach beginning band kids. I like to have the chords change with what I play, but there is no specific form to what I'm doing...so if say the kids mess up a measure that goes Bb, F7, then I want to be able to repeat that on the fly, and I can easily do that if I am at a keyboard and just hammering out the melody on the right hand and playing block chord changes on the left.

Summer break is coming, and if this is not something available, I am willing to fork and make it...

There is a slight delay (<1 sec) when you change the chord on the keyboard to get the backing track updated, so it's not pure real-time like vArranger, but it should not be a problem for your use case.
