Got a slightly annoying issue. When I add a new track to a project, I find that my matrix settings, specifically port 7 (mic), 9+10 (keys), 13+14 (Octopre LE) become unchecked on the headphones and some times on the main monitor outputs and I have to check them again in order to route them. Obviously very time consuming. Never seem to have had this issue in the past (or not that I can recall). Any thoughts. Probably blindingly obvious and if so apologies.
