it only registers Cmin7 in fingered, in pianist it registers AbM79 (and #11s).

It's all pretty academic anyway since with 8 tracks of backing playing and 2 tracks of a pad on top you won't hear the difference.

If you want to play jazz like this play bass and piano only with on-bass in pianist mode and use all the inversions properly. Then you'll get all the subtleties. Otherwise it's a waste of time with all the automatics going.

Let's face it, once your past 9ths there's usually 2 or 3 ways of naming the same chord anyway depending on root and other stuff...
