ardour_ui.rc problem

Hello all… I’m new to ardour and I need help with this file: /etc/ardour/ardour_ui.rc

I can’t change the size of the ardour fonts. I tried to edit the file and change the font codes (used gtkfontsel to get these codes) with no success…

I found these posts on this site:
but none of the ardour_ui.rc files they suggest work for me. Some colors change but always the same font size…

Why is it so difficult to find sample ardour_ui.rc files anywhere?..
I really like this one: :wink:
Can I get it somewhere?

Am I missing something obvious?..
