Thanks for the information.
Can you provide some more information about your setup? If your H90’s MIDI output is connected to the amp switcher, I would assume that the reason for this is you want to load Programs on the H90 and have corresponding amp settings, so you would need to configure this per Program.
If that is not the case, what is the goal of your setup and having the H90 transmit MIDI messages to the amp switcher?
