I know, it looks incredible. It popped up on my YouTube feed and I got super excited, but then I thought "I bet this is going to be at least $800." I was wrong in the worst possible way.
Can't help but think if they could sell that for, idk, $300? even $400. You'd get all kinds of people using it in fun ways.
-- ON another note, a few months back some guy posted here how he made a very simple midi device for his young daughter with a raspberry pi or the like. I do wonder if you could make a pocked-sized EQ-mixer with crossfade with this kind of interface. Do you know of anything like that?
