The C Dimished chord has only three notes. And the C Dimished Seventh chord has four notes. In either case please don’t use five fingers because it’s gonna hurt. (Grin)

Buddy, to the best of my knowledge the KN7 keyboard is receiving confusing chord messages so it does not understand what to do. I am with Rog on this one -- check, in your window, the chord recognition, if it’s fluttering you have your answer.

You know people do the same thing with the Bible, when a problem occurs it is the book and not themselves. Buddy, this is not meant for you.
