It's hard to see because the CS80 V3 GUI unfortunately is too fuzzy, but the CS80 V3 GUI do dispplay correct for both IL and AL. IL is shown as 0 to -5, and AL is shown as 0 to 5 on the CS80 V3 GUI. That's correct.
But in the value display that show the current parameter value, IL don't show the negative values, that it should.
It's a detail like other threads in the forum show, then CS80 V3 have much worse issues, that's much more important to be fixed. But fixing this detail should'nt take long i suppose.
It is important for the understanding of what the IL does, that it show negative values in the parameter value display. especially when it's hard to read the GUI.
