Ok actually I think it works fine now, at first I saw the visual response and also had some other issues with the MIDI that made it look and sound like the program is loaded after a really long delay through MIDI.
But then I checked it further, and in fact the signal of the new loaded program (which is what matters the most) is already heard a while before the program is visually loaded on the H90 screen & leds, so the response itself is pretty much ok.
I want to test it a bit more to be sure, but for now seems like the H90 is doing the job also for live scenarios and programs switching through MIDI.
