Its in the
documentation hereThe documentation should have pointed to project templates not track templates :)
Mix recall templates really is an extension added to project templates. When you save a project template file it will now additionally save any mix recall state that is present. i.e. the templates themselves can reference mix scenes and any project derived from this template will automatically inherit the mix scenes referenced by the template so
they’re ready to use.
For example you could have the template have scenes with different solo mute states, or even different combinations of effects that can be switched in via the mix scenes.
To save a mix recall template, you create a project with the desired mix scenes, then save the project as a template file. When you save, all the referenced mix scenes will be saved with the template.
There was a
thread here that requested a different use case for this. Here is
