Basically, when I patch the CV of sequencer B into sequencer A's transpose port, it ALSO transposes sequencer C.  But it only transposes C by a half-step up or down total (in other words, it seems like the voltage transposing C where it shouldn't isn't as strong as normal, like it's getting a small amount of the voltage getting sent to sequencer A, if that's even possible! )

I have on of the new MIDI-transposing Komplexes  if that makes a difference. 

I'm only sending clock from Logic to Sequencer A in this case, so I have no idea why B is also sending CV to a second sequencer when it's only patched to A. 

Any help?

I tried resetting the Komplex and this didn't fix it.

While the patch is active and C is being transposed, gently wiggle the cable plugged into Sequencer A's transpose jack. If the half-step jump flickers on and off, it confirms a physical issue with that specific jack or the immediate surrounding circuit board.
