The effect I am talking about, should work on all sounds, and maybe even whole mixes...
One hit and note should be enough...to demonstrate the technique.
It must sound like the sound is always on the "edge" of time, like it is only moving "downwards" in space & time.
If you understand, I want the form of the sound to feel "elastic" like you are dragging the sound back and forth.
To manipulate early reflections and the tail length in an pattern...is probably a good start...
To use an stereo image balancing tool, to drag the sound towards the sides to the center might give the illusions of "falling".
Or that you get "sucked" into a black hole.
