I believe the first 12 columns (1-12) are static and don't change regardless of which of the 4 extended pages (columns 13-16) is selected. So when you toggle between the 4 extended pages only the assigned modulation paths will be shown (blue buttons). Take for example the A05 patch, only page 1 of the extended 4 pages show modulation path assignments (columns 13-16), the remaining 3 pages show no assignments.
Is that what you mean?
EDIT: So in other words, toggling between the 4 extended pages will only reflect what's been assigned in columns 13-16.
