I have the S5000 control surface and noticed a small issue for a long time and it’s still present in v1.90.
To reproduce:
1) set the strip rotary mode to ‘pan’ instead of ‘gain’.
2) find a mono input channel and set the pan to +2 (right).
3) notice that the strip LCD graphical representation of the pan looks about correct.
4) change the fader bank to another layer and then back again.
5) notice that the strip LCD graphical representation of the pan now looks perfectly centered (which seems to be a bug).
Some other pan values also exhibit strange graphical differences.
