Hello,
While the documentation isn't finished you could look at the Actions/Show control section of the CueCore & VisualDMX manual.
For example you want to start a playback on each workday at 18:00.
Using the 3 groups of 4 buttons on top of the program we goto Memories -> Action
You add a Scheduler action source to the list on the left.
Next you add an action (on the right) en select edit.
Some action sources have multiple type's of triggers, in this example we want "WeekdayAndTime"
Now change the trigger and select Monday thru Friday at 18:00:00
On the right we add a Action task of the type "Playback button"
The identifier is the index of the playback button.
