In my project, if I click on any of the rectangles (corresponding to the effects) in the left view, it will be in focus (pink) and the right view (the knobs) will display the settings corresponding to that effect. If I click on a tab in the right view, the rectangle corresponding to the effect of the tab will be in focus.
If I double-click on any of the rectangles, the view of the rectangles will hide and the view of the knobs will fill the entire screen (like image 2).
The justification for the right view is always being displayed on devices> + -900px is that after the initial setup work (choose effects, test, connect) I see that the person will spend more time changing the values of the knobs. At least that's the behavior I observed of myself.
For small screens I thought the tabs would make it easy to quickly select another effect without having to keep going and going back to the connections screen (rectangles view).
A usability study would be very important, but unfortunately it is out of my research focus today.
Thanks for your feedback
One suggestion for the Mod team is to do is do a split screen, where on one side would be the connections and another on an effect in focus. Example image:
In this mode, on the left side could disable parameter changes and footswitches to make it easier to reposition the effects on touch screens.
Bonus: I believe that replacing one effect with another - which is so important for testing purposes on a device with a wide range of audio plugins - is quite complicated (remove effect, add another effect, reconnect) compared to other equipment ( Zoom, rolland, line6). Maybe this idea of split-pane might simplify this a bit.
(At least I intend to do something like this in my project in the future)
