I think you mean that adjusting any one hardware control would snap the screen view to the appropriate layer? As an Interaction Designer, I think this idea has legs, but there are some subtleties to it that may be good to think about:
– Would you want the display to “snap back” to the prior view that was selected via the screen? E.g. If you had the GEQ view up, then adjusted the PEQ (so now it shows that view), where would you want the view to land?
– Are there any scenarios you can envision where it would actually be helpful to have “double the real estate” by having soft controls on the screen for one parameter, but be using the hardware independently?
– If the view “stuck” on one channel by moving the hardware control, would you want every channel to have that same view?
There are probably more, but I gotta get to work.
