How to play blend track audio based on value?

Question

Hello,

I am trying to set up a blend track that plays the source sounds as the value increases or decreases. For example; a player interacts with a lever; instead of having a sound loop, it would play as the lever moves and would essentially move the playhead of the source forward/backward as the values change.  The idea is to prevent a noticeable loop as the player slowly interacts with said lever.

Can anyone provide an idea as to how to accomplish this, either with RTPCs or some other setup?

Thanks!
