What about at least just a text-based UI for preset management? MIDI is cool and all, but my primary use for this is with a camera input and a DAWless modular system and have no plans to dedicate a controller to this (would I even be able to use MIDI and UVC input simultaneously?). . . so using MIDI to manage more than 3 presets becomes kinda impractical (for me) as it means plugging/unplugging things every time I want to manage presets beyond those 3, instead of doing it easily on the fly.
Perhaps a compromise could be exporting/importing presets to/from a PC? Still cumbersome and not ideal, but if I’m going to interrupt my workflow, I’d rather it just be plugging into a laptop and drag/drop some things, or click some buttons in a preset librarian, as opposed to fussing around with MIDI mappings (and needing to remember/reference those on top of everything else I already need to remember/reference for the rest of my gear).
