I use the Disaster Area DMC-6 to do what you’re wanting. Easy to set up and you don’t need to line up the presets “lined up” as you describe. For instance you can have one program to call up Preset 11 from the first H9 and Preset 87 from the second; then press another button and pull up preset 65 on first and 38 on the second…and so on. You have room to store about 400 preset combinations, I believe, but I’ve only got maybe 50 at the moment. The instructions were well written and straightforward, but when I ran into a question I got a very fast and helpful response from them.
