I simply would like to have different assignable. Outs for drums and bass parts you can do it now but it is cumbersome if we could control bass and drums with its own dedicated outputs we could have a much better live mix and give it a band like flavor and allow the sound guy to mix like a band in larger Events even if it is dry that would be ok I could add a reverb to the post I would like that. It poss with the units now but if there was a button on board to control that that would be nice. it poss with the keyboard mixer to boost but what I am talking about a step line to the board for drums and bass.
