When we originally starting working on the H9, there were going to be two expression pedal patches, but when people saw how the UI would actually need to work to do that, they got angry and wanted only a single expression pedal patch. I think the problem is that when there were two patches there was one step to choose which patch you were looking at / modifying and then another step to make the actual assignments. Some people already find just making the actual assignments perplexing enough and adding another layer on top of that would break some people's brains unfortunately.
