I just saw that pic of new Casio board and decided to think out loud.

I'm thinking how nice it would be to have a controller with great action (of course.) But here's the thing I would like. A touch screen that would mimic the computer program like Kontakt, etc. Then I could have control of instruments without having to go to computer. Since we probably will never see a mainstream controller with a built-in computer, this would be the next best thing.

Future Controller? You can't control the future...

36251, I am sure all the big DP makers would like to ask you this: How much would you be willing to pay for it?

I think the VAX77 already does that to some degree, but minus the hammer action keyboard.

Here we are: VAX77 & MainStage

Well, I guess you want a much bigger screen, so you can do everything you can on the computer......

As tablets improve, DP makers would simply do well to integrate to an App as an workstation or stage interface, not just as a peripheral to connect to.

But the past... High Past Filter, Low Past Filter...

As its already been stated the vac kind of does that but I've been using a similar setup by using a iPad fixed to the stand to control various elements particularly Roland's Integra 7

I replaced the stand of my N1 with a 24" touch screen.... kind of doing what you want may be....
