I have finally found a tutorial I can use to create my buttons slideshow, originally its meant for images slideshow but I decided to use the same technique just using buttons.

The tweaked technique consists by grouping buttons and creating an animation for each group to slide out, and then adding slide left trigger to activate the animation, of one group of buttons sliding out and next group of buttons sliding in, and then to get the animation to reverse I add a reverse play action by the swipe right trigger to the existing buttons on the screen.
I then animated the lines on top to get animating sound bar animation on top of the buttons by animating the clipping on the buttons.
