[Q on MX] Need play,pause, scrub bar controlls

Hi,
Just wonding if someone knew of a tutorial etc. that could point me in the right direction.

I have a presentation with several slides.
The scenes play in order: slide1, slide2, slide3, slide4…
At the start of each “slidex”, I play its sound track.

Now, I would like to add controlls that would:
play, pause, mute, and a scrub bar. I suspect the scrub bar will be the hard part??

Any help appreciated.

Thanks!
