I agree that the Floorboard UI is a little bit rough. It has a “hand made” unpolished feel that I sorta like. I wish the fonts were a little larger as I find them hard to read on screen. I don’t yet understand all that it can do, especially the logic of how it manages storing and retrieving patch libraries. I think it makes a lot more sense in the context of the physical layout of the GT-100 processor; it’s been ported to work with the Katana. That said, it’s very useful and gives another window into how the “hidden” programming of the Katana works, and unlocks a lot of additional capabilities.
