I was exploring in this post and discovered that the edit path originally stated above is incorrect for LPX 10.4.8.
The path is; Logic Pro X 10.4.8.app/Contents/Plugins/exs.res/Contents/Resources/esx24ii_back.png
Interestingly, ALSO, these are simple png pictures and editable using almost ANY graphic editor with layers.
I used a copy of Gimp and in minutes had some progress.
Yes, there are all the buttons, thumbs, and verts and it would be a serious graphicical project in itself, to get it all done.
Getting it from ValliSoftware, is probably a good route.
I don’t propose to take away any credit here from ValliSoftware or input from fisherking.
Just pointing out some specifics.
A really great innovation here.
Thanks Valli.
