Issue: Dynamics and Vibration C4D R13

Hello,

I am attempting to create a scene where text is vibrating and falls off a central block onto a floor. Using Cinema 4D R13 I have been playing with dynamics and the vibrate tag to try and create this effect - to no avail. The important element is that the text vibrates itself off the block, so the movement and eventual topple off of block is caused by the vibration.

The issues I am having is that the Vibrate tag and the dynamics both work by altering the global position. For example: if both are applied to a letter in my text (motext object) it does not vibrate. If I force the position it does not fall correctly.

I have also tried using noise and Xpresso without success. I would be very grateful if anyone on here knew of a way to create this effect. The important things being the vibration, and the realistic fall off the block.

(The only other issues it the fall needs to be the same each time, as I may need to tweak elements. I have had issues with the vibration causing the letters to fall in a different place each time - which is not going to work.)

Any help would be greatly appreciated, Thanks guys.
