The state of the “direct out” routing after a reset does not appear to be documented anywhere in the SQ reference guide (at least of 1.6.0 issue 2). As it is on the “routing” page and not with the other global settings, one presumes that it is reset along with mix settings and so should be documented with the other “reset mix” settings in section 17.1 of the manual.
And if it’s not reset with mix settings reset, perhaps a better place for the direct out settings is with the other global mixer configuration instead of on the “routing” page.
Context behind this request can be found in Direct Out default rant
