This video on the feedback view will show how to enable and manipulate the inputs to execute functions.
In the Feedback view you have the center of the screen with boxes for each of the devices in your project plus a box called System events.
Enabling the auto feedback on any of the devices will only enable feedback if the sequence have been assigned to a button. In the view below you can see when the Feedback is in manual mode, where all conditions are visible, here it is possible to add more feedback elements.
On the left you have the same options as in the Functions view.
A top tip is not to use the Sequences as actions, but instead use "Press Button" on one of the keypad or UI buttons. Then you know that the button and feedback will be synced to each other.
