I think the 12ch looks neet. I mix in my daw, so this would be a nice thing to use while recording, - don´t you think?
I really would like the EQ to be like on the M4 though, and a possibillity to move the connections to the back like on the Mackies would help things look tidy. And maybe a talk-back - but all this would make it more expenicive so..
