I was away for a while and didn’t get to work on this more. However, I’ll be finishing this up as fast as possible and will post updated versions of the panel in this thread.
I have also updated my MKS70, so I will be able to test the editing of tone B as well.
I have been struggling with the dropdown lists. It seems they work when I set them up outside of a uiGroup, but only send one value once I drag them in a uiGroup. I still don’t know wether that is a ctrlr bug, or if it’s me doing it in a wrong way.
