I was able to test this. At first right out of the box Mr Quinn puts a lot of chords tone embellishments other than the triad in his groove based on the transcriptions. When I "disabled" natural selection AND "forced to simple arrangement [non-embellished]" I do see we lost all the major 7ths, however, he continued to still slip in the sixths and nineths.

I guess I have confirmed your observations. Sounds very nice, but I can appreciate that you may not want that extra flavor in your chord backing. This is simply the way BIAB RTs do what they do.

So let me just add. BIAB is not the only tool which can add a strum accompaniment. There are Kontact libraries which can provide an alternative backing.
