Essentially, the LEDs and trim around knobs would change color based on what's selected for editing.
Visually, it would look similar to changing the UI color in Proxima and The Legend HZ.
"All" could be red, "1" could be blue, "2" green, and so on. The voice editing buttons 1-8 could reflect the corresponding colors.
Global controls could always keep the "All" color.
I think this would make editing of layered patches less error prone without significantly altering the otherwise effective workflow.
Just an idea
