It’s a common sentiment that manufacturing something like I’m suggesting would have to be priced way beyond what the market would accept. I disagree. In the pro sound space, there are many examples of control surfaces that are more technically advanced and less expensive than what’s available in the lighting controller space. Offerings from Behringer, Avid, PreSonus etc have virtual scribble strips and motorized faders for $500 - $1000. Slate Media’s Raven MTi Core Station at $3000 is another approach for a fully formed surface. Imagine Onyx with a surface like that one. Audio isn’t inherently less complex than dmx.
