Hi Dreeko.

As I understood, you have all Keyframes in the same Timeline. You want it to playback when pressing a button, and when releasing the button the Timeline should go back to the start. Correct me if I'm wrong.

From what you describe it seems you need to address several problems.

1- The mouth shapes are all visible at once.
One solution is to make them invisible by default, that is, while there's no Keyframe recording, switch OFF their Visibility from their Tweak Menu. Now create a Keyframe for each mouth shape that switches their visibility back ON.
This way the shapes won't be visible unless their respective Keyframe is powered ON, by the Timeline's Playhead or else.

2- To make the Timeline play and go back to the start:
Stamp a Timer. Wire the Timer's Output port into the Playhead. This can be done while the Timeline is open -when grabbing the wire a port at the bottom of the Playhead will appear.
Now tweak the Timer's duration to be equal to the Timeline's, and set it to be Positional. Wire the Controller Sensor output into the "Start Timer" port.
This method will keep the Timeline powered when no button is pressed, in turn powering ON the closed mouth Keyframe.
