Move SplineController in rhythm of song

[electricpunch]

I checked "00_SplineController" demo scene and as understood Speed is passed worldUnits per seconds (I'm using Absolute posiiton). If it's true - I can simplyfy the question: How to calculate Speed value of Controller to achieve the target position on spline using Position value. For example, controller Position = 0 and target position = 1, how to calculate speed of controller? Thanks in advance.
