I confirmed your assessment based on looking at the notation versus the chord chart. No surprizes here for me, especially since this falls into a Jazz category. The RT takes a lot of liberties. Many in this thread have acknowledged this.

How do you tell BIAB to play specific chords and not stray from them?
Is there a setting in BIAB for this?

By the way, the answer to your question is NO. grin

I do have my own personnal workaround for this. One way is to use the "Chord Track" to send to a VSTi which has more control over chord voicing and extra notes, as I indicated with the Toontrack sessions organ (but you have to be working in your DAW). Or I use Scaler which voices the chord exactly as I specify.

Good luck.
