I was. Sorry if that was unclear. I assume your MC8 features are the same as the MC6 Pro here. My suggestion was to set the transmitting MC8 switch at maximum sensitivity. Then use that as a diagnostic to determine if the small delay is on the MC8 controller end, or on the H90’s reception of that MIDI CC.
I guess it could also be caused by a lot of unrelated MIDI messages being transmitted ‘simultaneously’ (serially) by the same switch. As the MC6 Pro can transmit up to 32, it’s worth mentioning as another possible cause.
