"H9 A & H9 B = Set the XMT CHannel and RCV CHannel to same number [1-16 pick one]

H9 A Output Mode = Transmit [XMT].  H9 B Output Mode = THRU.

H9A XMT CC = PED > CC 15 (arbitrary).  H9 B RCV CTL = PED > CC 15 (match to XMT)"

Yes, thanks those are exactly the settings I tried, as well as the General settings and Midi settings in H9 Control menu. I will experiment more with synching up via midi but the fact that you can't visually confirm anything in H9 Control while midi-ing kills it for me. I guess a Y cable to two units will do.
