Debguy,
I have tried to work with pausing and the problem that I am encountering with pausing is that what ends up happening is the displaying of the disks is delayed and while the buttons are delayed they are not disabled, so it still allows that audio to become out of sync.

Speak["You have chosen three as the number to be used."]

I am not familiar at all with Dynamic, (I assume that it woks differently from Manipulate) so it may take me while to get acquainted with its operation. I would also assume that SetterBars and Buttons work differently, so that for instance I could not just set up my four buttons (Stat over, Less, More and ALL) as a Setter Bar. Many thanks for responding and for working on this, for the first time in a few days I have some hope that I may be able to get this working.*)
