After posting the above, I tried one other thing.

Initially, I had the output of the PitchFactor coming out of the Output 1 (mono) jack.  I took it out of Output 1 and put my cord into the Output 2 jack.  Once I did that, the Pitch B (or Pitch B and D) worked appropriately.  Pitch A (or Pitch A and C) was not happening.

Do both pitches only work with stereo?
