Changing chords via midi CC message?

[RobertBeach00]

In the manual's Appendix, for MIDI CC (Control Change) Implementation, to change the chord it indicates CC # 26, values 1-6.   But, there are seven chords that can be chosen.    Same thing for the Chord Type on CC #27.    Are these supposed to be values 0 - 6 ?  See attached image
