When enabling "Use auto feedback" in the feedback section, all of the available feedback, based on the sequences you have used in the project, e.g. Power, Source and Control (e.g. Mute) will be kept in-sync with the control system.
If a device driver has a lot of feedback sequences implemented like i.e. a mixer or a video matrix, then it will only ask for feedback on the sequences that is used in the Project. In example, if 3 sliders are added for controlling mixer input level 1-3, then the feedback processor will only ask for those channels.
