I am not using per-program amp settings. I have a 3 button AUX switch connected to the H90, with each switch configured to select a different amp on the switcher with a MIDI CC.

This is a smaller board, so the goal is to use the H90 partly as a simple MIDI controller for the amp switcher in lieu of a dedicated controller.

I mostly just use a single H90 program, and have a couple of other external effects in the inserts that I control with an additional 2 button aux switch.

It all works just how I want it, unless I need to make a tweak to the program “on the fly” and the “save” makes the amp switcher sad.
