Are you loading the tuner with a MIDI CC or a MIDI program change? It is possible to load the tuner with a program change in the latest firmware release for the H9, but H9 Control doesn't show you that option. (We had some internal miscommunication about that feature…) The next release of H9 Control should show you that option.
You shouldn't need to do anything special here. The 2nd H9 needs to be configured to listen to the correct MIDI channel of course and that MIDI CC needs to be mapped to the correct pedal function. If that's set-up correctly, I'd plugin the MIDI cable into a computer and make sure that the expected MIDI message is actually being sent. You can use MIDI Monitor on Mac or MIDI Ox on Windows to do this.
The H9 triggers its pedal function when the CC value crosses 64. It sounds like when you press the switches on the MkIV pressing once toggles on to 127, pressing again toggles off to 0, pressing again toggles on to 127, and so on. So, every other press effectively does nothing. Is that behavior not configurable on the MkIV?
