All I tried to say is that a fancy graphical touch UI on the hardware wouldn't be the solution to all problems.
Nothing beats dedicated knobs and buttons for quick adjustments.
I agree...a touch UI does not solve all problems.
But let’s take the output section of the KPA as an example. Currently on the hardware, in order to get to the output EQ’s, we need to press the Output button, the a number of other button presses are necessary (I don’t remember how many as I’m not in front of my KPA) to get to the EQ you want to adjust. One more button press to exit.
It works fine for the most part, but it is a lot of button presses, and just as big a distraction from playing the gig as anything.
If you look at the touchscreen on the QC, a simple swipe down gets you to the output section, (where you can see ALL the components) one touch selects the component you want to work on, and then the footswitches - which are also basically knobs - are used to make changes.
This is attractive to me. The fact that you have the option to adjust on the touchscreen itself OR use physical knobs is excellent.
The same goes for editing the stomp and FX parameters on The KPA. On some stops it’s rather simple as there are few controls and they all fit on the first page. On others, again you have to hit many buttons to access the control you’d like to adjust.
A more immediate way to access all the parameters, whether it’s a touchscreen or not, would be of great benefit to me.
